    Language:English   Publishing type:Research paper (scientific journal)  

    PURPOSE: The frequency of pancreaticoduodenectomy is increasing in oldest old patients owing to population aging. We aimed to clarify the clinical significance of pancreaticoduodenectomy in patients aged ≥ 80 years with multiple underlying diseases. METHODS: A total of 649 consecutive patients who underwent pancreaticoduodenectomy from April 2010 to March 2021 in our institute were divided into two groups according to their age: ≥ 80 years (51) and ≤ 79 years (598). We compared mortality and morbidity between the groups. The age-related prognosis was analyzed in 302 patients who underwent pancreaticoduodenectomy for pancreatic ductal adenocarcinoma treatment. RESULTS: There were no significant differences in morbidity (Clavien-Dindo classification grade III or higher; P = 0.1300), mortality (P = 0.0786), or postoperative hospital stay (P = 0.5763) between the groups. Patients aged ≥ 80 years, who underwent pancreaticoduodenectomy for pancreatic ductal adenocarcinoma, had shorter overall survival than those aged ≤ 79 years (median survival time, 16.7 months vs. 32.7 months; P = 0.0206). However, the overall survival of patients aged ≥ 80 years who received perioperative chemotherapy was comparable to that of patients aged ≤ 79 years (P = 0.9795). In the multivariate analysis, the absence of perioperative chemotherapy was identified as an independent prognostic factor, while age ≥ 80 years was not. Perioperative chemotherapy was the sole independent prognostic factor in patients aged ≥ 80 years who underwent pancreaticoduodenectomy for pancreatic ductal adenocarcinoma. CONCLUSIONS: Pancreaticoduodenectomy is safe for patients aged ≥ 80 years. The survival benefits of pancreaticoduodenectomy for patients with pancreatic ductal adenocarcinoma aged ≥ 80 years might be limited to those who can receive perioperative chemotherapy.

    Language:English   Publishing type:Research paper (scientific journal)  

    PURPOSE: To investigate the utility of T1ρ and T2 relaxations for assessing the severity of liver fibrosis (F stage) and necro-inflammation (A stage) in patients with chronic liver disease (CLD). MATERIALS AND METHODS: We calculated T1ρ and T2 relaxations of the liver parenchyma in 82 patients who underwent liver surgery. F and A stages of enrolled patients were assessed by referring to surgically resected specimens. The relationships between T1ρ or T2 relaxation and F or A stage were assessed using one-way analysis of variance followed by Tukey's multiple comparison test, Spearman's rank correlation test and a receiver operating characteristic analysis. RESULTS: The T1ρ and T2 values of the liver parenchyma were significantly increased as the F and A stages progressed. The T1ρ and T2 values showed significant differences between F0 and F4, between F1 and F4, and between F2 and F4. In addition, T1ρ values showed a significant difference between F0 and F3 as well. The highest diagnostic ability for fibrosis was obtained when differentiating ≥F3 from ≤F2 using T1ρ: the sensitivity was 82.8%, the specificity 79.2% and the area under the curve (AUC) 0.87. The sensitivity and AUC of T1ρ relaxation (46.9% and 0.67) were significantly higher than those of T2 relaxation (29.7% and 0.60) for differentiating ≥A1 from A0. CONCLUSION: T1ρ and T2 relaxations have potential as a biochemical marker for assessing the severity of liver fibrosis and necro-inflammation. T1ρ relaxation may be slightly superior to T2 relaxation in terms of diagnostic ability for liver fibrosis and necro-inflammation.

    Purpose : The specific objectives of our study were to examine whether the visibility of hepatocellular carcinoma (HCC) lesions on early phase abdominal contrast-enhanced computed tomography (CT) images can be improved by optimal pseudo-colorization with a rainbow color map. / Methods : The chromaticity of grayscale and rainbow color maps displayed on a medical liquid-crystal display was measured using a colorimeter. The differences in the chromaticity, bE00, between the HCC lesion and liver parenchyma in 22 cases were evaluated. The rainbow color map was revised by changing only the window level (WL) to match the HCC lesion with a peak of bE00. Visual evaluation of the 22 cases was performed using Scheffeʼs paired comparison by ten observers. The average psychological measurement (a) was calculated using the grayscale, rainbow color map, and revised rainbow color map to examine the effectiveness of the proposed method. / Results : In all cases, the a measure was highest in the order of revised rainbow, grayscale, and rainbow. These results indicate that the visibility of HCC lesions in early phase abdominal contrastenhanced CT images could be improved by modifying the pseudo-color map with optimal colorization based on bE00. / Conclusions : The visibility of HCC lesions in early phase abdominal contrast-enhanced CT images was improved by shifting only the WL setting so that the HCC contrast would match the pixel range with higher bE00 on the rainbow color map. This method can be applied to various cases and color maps, and the visibility of the target lesion can be easily improved.

    【目的】本研究は、腹部造影コンピュータ断層撮影(CT)動脈相における肝細胞癌(HCC)病変の視認性が、rainbowカラーマップを使用した適切な疑似カラー画像化によって改善することを目的とした。【方法】医用画像表示用液晶ディスプレイに表示されるgrayscaleおよびrainbowカラーマップの色度を、色彩輝度計を使用して測定した。2017年4月から2019年12月までに腹部造影CT動脈相を撮影された22症例のHCC病変を対象とした。22症例において、HCC病変と肝実質の間の色度の違い(ΔE00)を評価した。適切なカラー画像化として、ウィンドウレベル(WL)のみを変更して、HCC病変のコントラストがRainbowカラーマップのΔE00の最も高いピクセル範囲に一致するようにRainbowカラーマップを修正した(revised rainbow)。10名の観察者によりScheffeの一対比較法を用いて22症例のHCC病変の視認性を評価した。提案した手法の有用性を調査するため、grayscale、rainbow、revised rainbowそれぞれにおいて、平均嗜好度(α)を求めた。【結果】すべての症例において(α)は、revised rainbow、grayscale、rainbowの順に高かった。これらの結果は、提案手法であるΔE00に基づいた適切な疑似カラー画像化によって、腹部造影CT動脈相におけるHCC病変の視認性を改善できることを示している。【結論】腹部造影CT動脈相におけるHCC病変の視認性は、HCC病変のコントラストがrainbowカラーマップ上のより高いΔE00のピクセル範囲と一致するようにWL設定のみをシフトすることによって改善された。本提案手法は、さまざまな症例やカラーマップに適用でき、標的病変の視認性を簡単に向上させることができる。(著者抄録)

    Hyperintense Liver Masses at Hepatobiliary Phase Gadoxetic Acid-enhanced MRI: Imaging Appearances and Clinical Importance.
    Gadoxetic acid, a hepatobiliary-specific contrast medium used for MRI, is becoming increasingly important in the detection and characterization of hepatic mass lesions. This medium is taken up by functioning hepatocytes, and the liver parenchyma is strongly enhanced in the hepatobiliary phase (HBP), during which hepatic mass lesions without functioning hepatocytes commonly show hypointensity. However, some hepatic mass lesions show hyperintensity in the HBP. Focal nodular hyperplasia (FNH) and FNH-like lesions show hyperintensity in the HBP owing to the uptake of gadoxetic acid by hyperplastic normal hepatocytes. The tumor cells of some types of hepatocellular adenoma (eg, β-catenin-activated type, inflammatory type) and hepatocellular carcinoma (eg, green hepatoma) can show uptake of gadoxetic acid. Retention of gadoxetic acid in the extracellular space can cause hyperintensity of fibrotic tumors or hemangiomas during the HBP owing to the extracellular contrast agent characteristics of gadoxetic acid. During the HBP, peritumoral retention is observed in some tumors, such as hepatocellular carcinomas, gastrointestinal stromal tumors, and neuroendocrine tumors. Gadoxetic acid is excreted into the bile; therefore, biliary tract enhancement can be observed in the cystic components of intraductal papillary neoplasms of the bile duct. Intratumoral bile ducts can be observed in malignant lymphomas. Knowledge of these specific mechanisms, which can cause hyperintensity during the HBP depending on the pathologic or molecular background, is important not only for precise imaging-based diagnoses but also for understanding the pathogenesis of hepatic mass lesions. ©RSNA, 2019 See discussion on this article by Lalwani.

    Imaging features of undifferentiated carcinoma of the pancreas.
    INTRODUCTION: The purpose of this retrospective study was to evaluate imaging features of undifferentiated carcinoma of the pancreas. METHODS: The study group included eight patients with surgically resected undifferentiated carcinoma of the pancreas. Multidetector-row computed tomography (MDCT, n = 8) and magnetic resonance imaging (MRI, n = 6) findings were retrospectively reviewed. RESULTS: On MDCT, all eight cases were hypovascular with upstream main pancreatic duct (MPD) dilatation, and only 1 showed exophytic growth. Five cases (62.5%) showed necrosis/cystic change, and calcification was observed in two cases (25%). Calcification reflected tumour osteoid components. On MRI, haemorrhage and hemosiderin were observed in 4 of 6 (66.7%) cases. In addition, tumour thrombus in the splenic vein (n = 1) and intraductal tumour growth in the MPD (n = 2) were pathologically identified, although imaging studies only revealed 1 of these latter cases. CONCLUSION: Undifferentiated carcinoma of the pancreas may present as a tumour with haemorrhagic necrosis. Coexistence of calcification, intraductal tumour growth in the MPD and tumour thrombus may support the imaging diagnosis of this entity.

    Superparamagnetic iron-oxide-enhanced diffusion-weighted magnetic resonance imaging for the diagnosis of intrapancreatic accessory spleen.
    PURPOSE: To evaluate the diagnostic performance of superparamagnetic iron-oxide (SPIO)-enhanced diffusion-weighted image (DWI) for distinguishing an intrapancreatic accessory spleen from pancreatic tumors. MATERIALS AND METHODS: Twenty-six cases of intrapancreatic accessory spleen and nine cases of pancreatic tail tumors [neuroendocrine tumor (n = 8) and pancreatic adenocarcinoma (n = 1)] were analyzed. Two blind reviewers retrospectively reviewed the SPIO-enhanced magnetic resonance imaging (MRI) scans. The lesion visibility grades were compared and the diagnostic performance of SPIO-enhanced DWI was compared to those of SPIO-enhanced T2WI and T2*WI with the use of a receiver operating characteristic (ROC) analysis. RESULTS: The grade of lesion visibility was the highest on DWI [mean ± standard deviation (SD): 2.8 ± 0.3] followed by T2WI (2.3 ± 0.7, p < 0.001) and T2*WI (2.1 ± 0.7, p < 0.0001). Reviewers 1 and 2 correctly characterized the presence or absence of SPIO uptake in 34 of 35 cases (97.1&#37;) on DWI, 24 (68.6&#37;) and 25 (71.4&#37;) cases on T2WI, respectively, and 16 (45.7&#37;) and 17 (48.6&#37;) cases on T2*WI. The area under the ROC curve (AUC) of DWI was 0.974 and 0.989 for reviewers 1 and 2, respectively. For Reviewer 1, the AUC of DWI was significantly higher than that of T2*WI (0.756, p < 0.01), although it was not significantly different from that of T2WI (0.868, p = 0.0857). For Reviewer 2, the AUC of DWI was significantly higher than those of T2WI (0.846, p < 0.05) and T2*WI (0.803, p < 0.01). CONCLUSION: The diagnostic performance of SPIO-enhanced DWI was better than those of SPIO-enhanced T2*WI and T2WI for the diagnosis of intrapancreatic accessory spleen.

    Papillary renal cell carcinoma with massive hematoma mimicking hemangioma.
    It is extremely rare that papillary renal cell carcinoma has a massive hemorrhage. We report a case of papillary renal cell carcinoma with a massive hemorrhage which showed hemangioma-like imaging findings such as a globular discontinuous enhancement on the corticomedullary phase with a gradual centripetal fill-in pattern on the excretory phase on computed tomography and heterogeneously hyperintensity on T2-weighted magnetic resonance imaging. We also discuss a plausible mechanism explaining such imaging findings, with reference to pathological findings.

    Usefulness of a Pretreatment CT-Based Modified RENAL Nephrometry Score in Predicting Renal Function After Cryotherapy for T1a Renal Mass.
    PURPOSE: We investigated the usefulness of the modified RENAL nephrometry (mRN) scoring system for predicting post-cryotherapy renal function in patients with T1a renal mass. PATIENTS AND METHODS: A total of 75 patients with a T1a renal mass were enrolled. The mRN score was determined based on the tumor size, the tumor's exophytic/endophytic properties, the tumor's nearness to the collecting system, and the anterior/posterior location of the kidney. The change in the estimated glomerular filtration rate (ΔeGFR) was calculated as follows: ΔeGFR = 100 × ([pretreatment eGFR - eGFR at 6 months after cryotherapy]/pretreatment eGFR). Based on the ΔeGFR results, we classified the patients into two groups: a preserved renal function group (ΔeGFR < 10&#37;) and an impaired renal function group (ΔeGFR ≥ 10&#37;). We then analyzed the relationships between the mRN score and ΔeGFR and between the mRN score and the chronic kidney disease (CKD) stage. RESULTS: The mean ΔeGFR for all patients was 5.5&#37;. The mRN scores of the preserved renal function group (5.8 ± 0.3) were significantly lower than those of the impaired group (7.4 ± 0.3) (p < 0.001). When the mRN score cutoff value was set at 7 points, the mRN had 67.7&#37; sensitivity, 72.7&#37; specificity, 61.8&#37; positive predictive value (PPV), 76.1&#37; negative predictive value (NPV), and 70.7&#37; accuracy for predicting impaired renal function. For predicting a deterioration of CKD stage, the mRN had 92.9&#37; sensitivity, 67.2&#37; specificity, 39.4&#37; PPV, 97.6&#37; NPV, and 72&#37; accuracy. CONCLUSION: Our newly proposed modified RENAL nephrometry score was suggested to be useful for predicting renal function after renal cryotherapy.

    Impact of body mass index on CT attenuation of adrenal adenoma.
    OBJECTIVE: To investigate whether lipid metabolism-related factors regulate unenhanced CT attenuation in adrenal adenoma (AA). MATERIALS AND METHODS: Thirty-six patients with surgically proven AAs were enrolled in this study. The patients' underlying diseases were the following: primary aldosteronism (n = 24), Cushing's syndrome (n = 8), subclinical Cushing's syndrome (n = 3) and non-functioning AA (n = 1). Unenhanced CT attenuation of AAs and liver was measured. Pathologically, clear cell ratio (CCR) constituting each AA was qualitatively assessed. Clinical data including tumor diameter, body mass index (BMI), hemoglobin A1c, triglyceride, total cholesterol, blood cortisol and plasma aldosterone levels were also obtained. Simple and multiple linear regression analyses were performed to evaluate the radiological and clinicopathological factors associated with CT attenuation of AAs for all patients and separately for 25 patients with primary aldosteronism or non-functioning AA. RESULTS: For all patients, there was a significant correlation between CT attenuation and each of CCR, BMI and blood cortisol levels (p < 0.05). For patients with primary aldosteronism or non-functioning AA, there was also a significant correlation between CT attenuation and CCR or BMI (p < 0.05). CONCLUSION: In addition to pathological factors, lipid-metabolism-related factors including BMI and blood cortisol levels can affect unenhanced CT attenuation of AA.

    Relationship Among Tumor Attenuation Value of Pre-contrast Computed Tomography (CT), Washout Rate and Constituent Cells in Adrenal Adenoma: Proposition of a New Approach for Diagnosing Adrenal Adenoma on Dynamic CT.
    AIM: To elucidate the relationship among tumor attenuation of pre-contrast-enhanced (TApre) computed tomography (CT), washout rate and clear cell ratio (CCR) in adrenal adenoma (AA) and propose a new approach for diagnosing AA on dynamic CT. MATERIALS AND METHODS: The training set consisted of 43 AAs and 15 non-AAs, while the validation set comprised 44 AAs and 11 non-AAs. Using the training set, the pairwise correlation between CCR, TApre and washout rate in AA was evaluated by linear regression analysis. A predictive formula for diagnosing AA was established by multiple logistic regression analysis using washout rate and TApre. Using the validation set, the diagnostic performance of this formula was investigated by comparing with the conventional diagnostic criteria: TApre ≤10 HU or washout rate ≥an optimal threshold calculated in the training set. RESULTS: Washout rate increased as CCR decreased, and as TApre increased. The formula predicting the probability of AA was: p(AA)=1/{1+exp(-1.5257+0.4923× TApre-0.3264×washout rate)}. Diagnostic performance of this formula was sensitivity of 93.2&#37; and accuracy of 89.1&#37;, while for the conventional diagnostic criteria, sensitivity was 81.8-86.4&#37; and accuracy 81.8-83.6&#37;. CONCLUSION: The diagnostic potential of dynamic CT for diagnosing AA may be improved by changing the threshold of washout rate based on substituting TApre for CCR.

    Amide proton transfer imaging to predict tumor response to neoadjuvant chemotherapy in locally advanced rectal cancer.
    BACKGROUND AND AIM: The amount of proteins and peptides can be estimated with amide proton transfer (APT) imaging. Previous studies demonstrated the usefulness of APT imaging to predict tumor malignancy. We determined whether APT imaging can predict the tumor response to neoadjuvant chemotherapy (NAC) in patients with locally advanced rectal cancer (LARC). METHODS: Seventeen patients with LARC who underwent a pretherapeutic magnetic resonance examination including APT imaging and NAC (at least two courses) were enrolled. The APT-weighted imaging (WI) signal intensity (SI) (&#37;) was defined as magnetization transfer ratio asymmetry (MTRasym ) at the offset of 3.5 ppm. Each tumor was histologically evaluated for the degree of degeneration and necrosis and then classified as one of five histological Grades (0, none; 1a, less than 1/3; 1b, 1/3 to 2/3; 2, more than 2/3; 3, all). We compared the mean APTWI SIs of the tumors between the Grade 0/1a/1b (low-response group) and Grade 2/3 (high-response group) by Student's t-test. We used receiver operating characteristics curves to determine the diagnostic performance of the APTWI SI for predicting the tumor response. RESULTS: The mean APTWI SI of the low-response group (n = 12; 3.05 ± 1.61&#37;) was significantly higher than that of the high-response group (n = 5; 1.14 ± 1.13&#37;) (P = 0.029). The area under the curve for predicting the tumor response using the APTWI SI was 0.87. When ≥2.75&#37; was used as an indicator of low-response status, 75&#37; sensitivity and 100&#37; specificity of the APTWI SI were obtained. CONCLUSION: Pretherapeutic APT imaging can predict the tumor response to NAC in patients with LARC.

    Imaging pitfalls of pancreatic serous cystic neoplasm and its potential mimickers.
    The aim of this article is to clarify diagnostic pitfalls of pancreatic serous cystic neoplasm (SCN) that may result in erroneous characterization. Usual and unusual imaging findings of SCN as well as potential SCN mimickers are presented. The diagnostic key of SCN is to look for a cluster of microcysts (honeycomb pattern), which may not be always found in the center. Fibrosis in SCN may be mistaken for a mural nodule of intraductal papillary mucinous neoplasm (IPMN). The absence of cyst wall enhancement may be helpful to distinguish SCN from mucinous cystic neoplasm. However, oligocystic SCN and branch duct type IPMN may morphologically overlap. In addition, solid serous adenoma, an extremely rare variant of SCN, is difficult to distinguish from neuroendocrine tumor.

    Clinical outcomes of symptomatic arterioportal fistulas after transcatheter arterial embolization.
    AIM: To evaluate the complications and clinical outcomes of transcatheter arterial embolization (TAE) for symptoms related to severe arterioportal fistulas (APFs). METHODS: Six patients (3 males, 3 females; mean age, 63.8 years; age range, 60-71 years) with chronic liver disease and severe APFs due to percutaneous intrahepatic treatment (n = 5) and portal vein (PV) tumor thrombosis of hepatocellular carcinoma (n = 1) underwent TAE for symptoms related to severe APFs [refractory ascites (n = 4), hemorrhoidal hemorrhage (n = 1), and hepatic encephalopathy (n = 1)]. Control of symptoms related to APFs and complications were evaluated during the follow-up period (range, 4-57 mo). RESULTS: In all patients, celiac angiography revealed immediate retrograde visualization of the main PV before TAE, indicating severe APF. Selective TAE for the hepatic arteries was performed using metallic coils (MC, n = 4) and both MCs and n-butyl cyanoacrylate (n = 2). Three patients underwent repeated TAEs for residual APFs and ascites. Four patients developed PV thrombosis after TAE. During the follow-up period after TAE, APF obliteration and symptomatic improvement were obtained in all patients. CONCLUSION: Although TAE for severe APFs may sometimes be complicated by PV thrombosis, TAE can be an effective treatment to improve clinical symptoms related to severe APFs.

    CT-guided radiofrequency ablation of osteoid osteoma in the long bones of the lower extremity.
    AIM: To present our initial experience with computed tomography guided radiofrequency ablation (RFA) of osteoid osteoma (OO) in our institution. METHODS: RFA was performed on eight patients (5 males and 3 females) with clinically and radiologically diagnosed OO (femoral neck, n = 4; femoral diaphysis, n = 2; tibial diaphysis, n = 1; fibular diaphysis, n = 1). Ablation was performed using an electrode with a 10-mm exposed tip for a total of 4-6 min at a targeted temperature of 90 degrees Celsius. No cooling system was used. The intervention was accepted as technically successful if the tip of the electrode could be placed within the center of the nidus. We defined clinical success as a disappearance within 2 wk after treatment of symptoms that had manifested at presentation. RESULTS: All procedures were technically successful. No major or immediate complications were observed. Clinical success was achieved in six of eight patients in the first procedure. A second procedure was performed for two patients who had recurrent or continued pain, and one of these cases was successfully treated. The overall rate of success was 87.5&#37; (7/8). No complication was observed. CONCLUSION: Our preliminary results indicate a favorable success rate and no complications and are compatible with the previous reports of RFA of OO.

    The prevalence of circumportal pancreas as shown by multidetector-row computed tomography.
    OBJECTIVE: To evaluate the prevalence of circumportal pancreas (CP) and any coexisting anomaly. In addition, three cases of surgically confirmed CP are presented. METHODS: The study group consisted of 317 consecutive potential liver transplant donor candidates who had undergone thin-section MDCT studies for the evaluation of vascular anatomy. MDCT images were retrospectively reviewed to assess the presence or absence of CP. If CP was present, the transverse diameter of the aberrant pancreatic tissue was measured on axial images, and the course of the main pancreatic duct (MPD) was classified into ante-portal (normal) or retro-portal. In addition, the prevalence of variant hepatic arterial anatomy was compared between cases with and without CP. RESULTS: Eight of 317 liver transplant donor candidates (2.5&#37;) were found to have CP at CT. The transverse diameter of the aberrant pancreatic tissue ranged from 5 to 18 mm (mean ± SD: 10 ± 4 mm). One of eight (12.5&#37;) showed the MPD to be retro-portal. A variant hepatic artery was noted in two of the of eight (25&#37;) patients, which was similar to the finding for those without CP [72 out of 309 (23&#37;)]. CONCLUSION: The prevalence of circumportal pancreas was 2.5&#37;.

    30歳、男性。急性膵炎の診断で前医に入院し、第2病日に低血糖が出現したが、第4病日より高血糖となりCTで膵全体にまだらな低吸収域が出現した。第8病日に当院に転院となり、ケトアシドーシス発症を契機に劇症1型糖尿病と診断されたが、その際のCTでは低吸収域は消失していた。膵生検では膵島は認められなかった。急性膵炎と低血糖が先行し、膵CT所見の経時的変化を観察しえた非常にまれな劇症1型糖尿病の1例を経験した。(著者抄録)

    腫瘤形成性膵炎は病態および病理組織学的な定義がいまだ明確にはされておらず、アルコール性慢性膵炎や原因不明な慢性膵炎が腫瘤を形成したもの、自己免疫性膵炎が腫瘤状を呈したものなどさまざまなものが含まれている。造影CTでは膵実質と等染を呈することが多い。Magnetic resonance imaging(MRI)、Endoscopic ultrasonography(EUS)、Endoscopic retrograde cholangiopancreatography(ERCP)でpenetrating duct signを認める場合もある。慢性膵炎や自己免疫性膵炎の典型的画像を呈していれば鑑別は比較的容易であるが、膵癌との鑑別が困難な場合も多く、画像所見や病理所見を総合的に判断することが必要である。(著者抄録)

    Groove pancreatitis(groove膵炎)のCT診断と鑑別診断、とくにgroove pancreatic carcinoma(groove膵癌)との鑑別上の問題点について概説した。Groove膵炎におけるCT診断の最も重要な役割は病変の存在診断であり、groove領域の異常所見を見逃さないように心掛けるべきである。Groove膵炎の病名は広く浸透しており、良性疾患としての側面が強調されてきた。Groove領域に病変を認めた場合、groove膵炎とgroove膵癌の両者の可能性を考慮する必要がある。Groove膵炎とgroove膵癌の画像診断上の鑑別点をいくつか紹介したが、両者の画像所見には重複が多く、鑑別困難例が少なくない。画像診断での鑑別に拘泥しすぎることなく、生検での確認を検討すべきである。(著者抄録)

    膵管内乳頭粘液性腫瘍(IPMN:intraductal papillary mucinous neoplasm)の3~10&#37;に通常型膵管癌を合併することが報告されており、IPMNを通常型膵癌のハイリスク群として重点的に精査し、経過観察を行うことで併存膵癌を早期に診断できる可能性がある。IPMNの初診時および切除時にはendoscopic retrograde pancreatograhpu(ERP)下膵液細胞診と術中膵管洗浄細胞診が、他の画像診断法では捉えられない早期の併存膵癌の同定に有用である。一方、IPMNの経過観察中に早期の併存PDACを診断するためのサーベイランス法とERPの位置づけは確立されておらず、今後急ぎ検討すべき課題である。(著者抄録)

    膵癌は診断時にすでに切除不能であることが多く,早期に診断し,切除可能例を増やすことが予後向上に重要であると考えられる.2009年版,膵癌診療ガイドラインでは膵癌の危険因子の1つとして糖尿病を挙げている.糖尿病の診療に際し,新規発症例(特に高齢発症例)や誘因のない血糖コントロールの急激な悪化例などに対しては膵癌を念頭に置き,積極的に腹部USや腹部造影CTなどを行う必要がある.小膵癌の場合,腫瘤自体の描出は困難であることもあるが,主膵管拡張や小嚢胞などの間接所見を見逃さずにEUSやERCPなどのさらなる精査を行うことで膵癌といえども早期発見につながる可能性がある.(著者抄録)

    multidetector-row CT(MDCT)が登場したのは十数年前であるが、その後MDCTは多列化し、現在では128~320列の検出器を持ったCTも臨床使用されている。多列MDCTの画像は、空間分解能が高く、isotropic imageのため三次元再構成が可能で、任意の方向から関心領域を観察できる利点がある。一方で、時間分解能にも優れており、呼吸性移動の影響を受けにくく、撮影タイミングの違いや遅れで診断が難しい病変にも対応が可能となった。これは、心・大血管領域だけでなく、腹部領域でも非常に有用と考えられる。本稿では、上腹部、特に肝臓領域における64列MDCTの有用性と、実際の臨床的な活用法について例を挙げて概説する。(著者抄録)

    Osteoid osteoma is a benign bone tumor traditionally treated nonoperatively or by operative excision. However, radiofrequency ablation (RFA) is being used increasingly for treatment of osteoid osteoma, as there are several reports supporting its effectiveness. We present a case of osteoid osteoma of femur in an 18-year-old boy. The patient complained of pain in right hip and knee joint. The osteoid osteoma lesion was successfully treated by percutaneous computed tomography (CT)-guided RFA using the cool-tip RFA system under general anesthesia. He had total pain relief within 24 hours following the procedure. No complications were recorded. He discharged on foot two days after RFA therapy. Complete regression of symptoms was observed at 2-year follow-up. CT-guided RFA for osteoid osteoma is a safe, effective and minimally invasive procedure with high success rate and lack of relapse.

    18歳男。9ヵ月前からの右股関節痛・右膝痛を主訴として近医を受診した。臨床所見および画像検査から、右大腿骨類骨骨腫と診断され、CTガイド下ラジオ波焼灼療法(RFA)目的で紹介受診した。ガドリニウム造影では増強効果を認め、類骨骨腫のnidusと考えた。MRIの脂肪抑制T2強調画像冠状断では、nidus周囲に高信号域を認め、周囲の浮腫性変化と考えた。CTガイド下RFAは全身麻酔下に仰臥位で施行した。術中術後に合併症を認めなかった。治療翌日より鎮痛剤の内服なしでVASは0点となり、治療2日後に独歩で退院した。治療3ヵ月後には臨床症状の再発は認めず、MRI上もnidusの増強効果はほぼ消失し、周囲の浮腫性変化も不明瞭化した。治療後2年経過後も症状の再発を認めていない。

    分枝型IPMNにはIPMNと離れた膵管より膵管癌が発生しうる(IPMN併存の膵管癌)。一方、IPMNは微小浸潤癌よりIPMN由来の浸潤癌へと進展する(IPMN由来の浸潤癌)。IPMN由来の浸潤癌ではIPMNより浸潤癌への移行像が認められることが必要である。IPMN併存の膵管癌が、IPMNと近接、もしくは一部接するとIPMN由来の浸潤癌との鑑別が困難となる。また、IPMN由来の浸潤癌も浸潤癌部が大きくなって、IPMN由来の根拠となっている移行像が破壊され、移行像が示されなくなった例も存在する。そうした例では移行像がないため、IPMN併存の膵管癌との鑑別が困難となる。IPMN併存の膵管癌とIPMN由来の浸潤癌とはその臨床病理学的特徴が明らかにされていないので、厳密な定義を満たす例に限って、検討を進めていく必要がある。(著者抄録)

    胆嚢癌の早期診断におけるdynamic MRの役割は,その高い濃度分解能を活かし,濃染パターンと形態学上の特徴を用いて行う鑑別診断と,隆起性病変の基部における漿膜下浸潤の有無を判定する深達度診断の2つに大別される.対象はUS等によって発見もしくは疑われた病変であり,精査として位置付けられる.具体的には,まず病変と胆嚢そのものの位置関係・オリエンテーションを把握し,病変を評価しやすい断面でdynamic MRを施行することが最も重要な技術的事項である.鑑別疾患においては,病変を隆起型と壁肥厚型にまず分類しそれぞれの鑑別対象疾患を想定して診断する.癌は,新生血管と間質両者を反映する遷延性濃染パターンを呈することで特徴づけられる.ただし,従来から言われている大きさによる因子も充分考慮する.深達度診断では隆起性病変基部での遷延性・遅延性濃染が漿膜下浸潤を示唆する.基部と病変全体が含まれる断面で撮像・評価することが肝要である(著者抄録)

    CTは非侵襲的に存在,質的,進展度の総合診断を行えるという点で,膵疾患の画像診断の中心的役割を果たしてきた.さらにMDCTの登場により,時間分解能と空間分解能は飛躍的な進歩をとげ,膵のCT画像も進歩した.高時間分解能は薄いスライス厚での多相性dynamic studyを可能にし,高空間分解能はMPR画像の画質の著明な向上をもたらした.これらのdynamic studyや高分解能MPR画像が膵領域におけるMDCTの最大の利点である.本稿では,膵実質相,門脈相,遅延相の三相撮像を基本とする膵のdynamic studyについて,造影剤の血行動態の観点から解説し,われわれの施設での撮影プロトコールを紹介した.MPR画像およびその発展形ともいえるCPR画像については,その臨床的有用性を強調し,最近のわれわれの試みについても簡単に述べた(著者抄録)
