Primary intraosseous carcinoma not otherwise specified (PIOC NOS) is a rare tumor assumed to arise from the epithelium, such as odontogenic cysts or benign tumors. Its clinical and imaging diagnoses are often challenging, especially in the early stages, as it mimics jaw cysts and benign tumors, and no specific findings have been identified. This report presents the case of a 66-year-old male patient with mandibular PIOC, highlighting the imaging findings over time. Magnetic resonance imaging (MRI) before symptom onset showed a cystic lesion in the right mandible with a soft tissue component. Both the fluid component and soft tissue exhibited low apparent diffusion coefficient values (1.0 × 10–3 mm2/s and 1.3 × 10–3 mm2/s, respectively). Subsequent MRI approximately 5 months later during symptom onset showed a slight increase in the soft tissue component. Based on the clinical and imaging findings, ameloblastoma was suspected, prompting a biopsy for confirmation. However, the histopathological findings showed squamous cell carcinoma (SCC). MRI performed approximately 1 month later exhibited significant tumor growth and extension beyond the jawbone, consistent with a malignant tumor. Histopathological examination identified areas with a basal layer in a palisading arrangement, indicating a pre-existing odontogenic cyst, and showed a transition from epithelial dysplasia to SCC. In addition, carcinoma cell invasion and proliferation into the cyst were observed. Based on these findings, PIOC of the right mandible was determined to be the definitive diagnosis.

Objective: To summarize the ultrasonography (US) and magnetic resonance imaging (MRI) findings of lymphoepithelial cysts (LECs) and dermoid cysts (DCs) and to discuss the hyperinternal echo in LECs based on histopathological findings. Methods: Patients who underwent US and MRI before resection and whose lesions were pathologically diagnosed as LECs or DCs were included (January 2010 to December 2023). Internal echo, convective flow, and Doppler signals were evaluated on US, while on MRI, we measured the apparent diffusion coefficient (ADC). Results: Surprisingly, all lesions (4 LECs and 7 DCs) had hyperinternal echoes. Convective flow and Doppler signals were observed in 2 of the 4 cases of LEC, and the ADC was high in these cases (2.4 × 10–3 and 2.0 × 10–3 mm2/s). In the two cases where they were not, the ADC was low (1.4 × 10–3 and 0.81 × 10–3 mm2/s). Various cells, such as lymphocyte cells, foam cells, erythroid cells, and keratin, have been found in the cystic cavity, which are thought to be the cause of hyperecho. Considering the ADC, the presence or absence of convection and Doppler signals is thought to reflect the ease of movement of the contents. In the DCs, neither internal convection nor obvious Doppler signals were observed. ADCs were quite low for cysts, which was a characteristic finding (1.1 ± 0.13–3 mm2/s). Conclusion: It is well known that DCs appear hyperechoic on US owing to the presence of keratin; however, it is necessary to recognize that some LECs are depicted as hyperechoic masses and have convective flow and Doppler signals depending on the content.

Objectives: The purpose of this study was to compare the image quality of ultra-high-resolution CT (U-HRCT) with that of conventional multidetector row CT (convCT) and demonstrate its usefulness in the dentomaxillofacial region. Methods: Phantoms were helically scanned with U-HRCT and convCT scanners using clinical protocols. In U-HRCT, phantoms were scanned in super-high-resolution (SHR) mode, and hybrid iterative reconstruction (HIR) and filtered-back projection (FBP) techniques were performed using a bone kernel (FC81). The FBP technique was performed using the same kernel as in convCT (reference). Two observers independently evaluated the 54 resulting images using a 5-point scale (5 = excellent diagnostic image quality; 4 = above average; 3 = average; 2 = subdiagnostic; and 1 = unacceptable). The system performance function (SPF) was calculated for a comprehensive evaluation of the image quality using the task transfer function and noise power spectrum. Statistical analysis using the Kruskal-Wallis test was performed to compare the image quality among the 3 protocols. Results: The observers assigned higher scores to images acquired with the SHRHIR and SHRFBP protocols than to those acquired with the reference (P < 0.0001 and P < 0.0001, respectively). The relative SPF value at 1.0 cycles/mm in SHRHIR and SHRFBP compared to the reference protocol were 151.5% and 45.6%, respectively. Conclusions: Through phantom experiments, this study demonstrated that U-HRCT can provide superior-quality images compared to conventional CT in the dentomaxillofacial region. The development of a better image reconstruction method is required to improve image quality and optimize the radiation dose.

OBJECTIVES: The objective of this study was to analyze the relationship between maxillomandibular characteristics and the severity of temporomandibular disc displacement in female patients with a skeletal class III (SKIII) pattern. METHODS: Fifty‑seven samples were included in the study. The evaluation of articular disc conditions was conducted using magnetic resonance imaging, while 25 cephalometric variables from lateral and postero‑anterior (P‑A) cephalograms were measured to determine their maxillomandibular characteristics. The samples were categorized into three groups based on the articular disc conditions: (1) normal disc position (NDP), (2) disc displacement with reduction (DDwR), and (3) disc displacement without reduction (DDwoR). The relationship between the maxillomandibular characteristics and disc conditions was examined through both basic statistical analysis and multivariate analysis using principal component analysis (PCA). RESULTS: The Kruskal–Wallis and Dunn–Bonferroni tests revealed a significant difference between the groups in terms of the deviation of mandibular characteristics observed on the P‑A cephalogram. The DDwoR group exhibited significantly larger menton deviation, ramal height asymmetry index, and total mandibular length asymmetry index compared to the NDP and DDwR groups. Moreover, the PCA successfully extracted all cephalometric variables into eight principal components. Among them, only the principal component related to mandibular asymmetry was able to differentiate the SKIII samples with DDwoR from the other groups. CONCLUSIONS: The findings of this study highlight a significant relationship between mandibular asymmetry and the severity of disc displacement, particularly DDwoR, in female patients with a SKIII pattern.

改良版cluster signal-to-noise(CSN)分析をデジタル口内法X線写真に適用してROC解析を行うことで、検者不要な画質分析法を開発できるか検討した。ステップ毎に深さが増すホール(0.05～0.35mm)をもつアルミニウムステップファントムとホールがないアルミニウムステップファントムを用いた。歯科用X線装置、輝尽性蛍光体イメージングプレート及びスキャナシステムを用いて様々な照射線量と画像キャプチャモード下でファントム画像を取得し、解析した。次に、ホールがあるファントム画像とホールがないファントム画像を解析し、真陽性率(TPR)と偽陽性率(FPR)を算出した。FPRに対してTPRをプロットしてROC曲線を作成して曲線下面積(AUC)を算出した。ホールがある同じファントム画像を用いて、8人の検者が検出可能なホールの数を調べ、検者の検出パフォーマンスとAUC値の相関を調べた。その結果、CSN分析により得られたAUC値は画質を反映し、画質に関する検者による検出パフォーマンステストを代替しうると考えられた。

Objectives: This study conducted a receiver operating characteristic (ROC) analysis by applying improved cluster signal-to-noise (CSN) analysis to digital intraoral radiographs and develop an observer-free method of analyzing image quality related to the observer performance in the detection task. Methods: Two aluminum step phantoms with a thickness interval of 1.0 mm were used for this study. One phantom had holes of increasing depth (from 0.05 to 0.35 mm) and the other had no holes. Phantom images were obtained under various exposure dose and image capture modes using a dental X-ray unit, a photostimulable phosphor imaging plate, and scanner system. These phantom images were analyzed using the FindFoci plugin in ImageJ software. Subsequently, true positive rates (TPRs) and false positive rates (FPRs) were calculated by analyzing phantom images with and without holes. We constructed ROC curves by plotting the TPRs against the FPRs and calculated the area under the ROC curve (AUC). Using the same phantom images with holes, eight observers assessed the number of detectable holes. Correlations between observer detection performance and AUC values were evaluated. Results: AUC values increased as the exposure dose increased and showed different tendencies depending on the image capture mode. The AUC values showed a high correlation with observer detection performance (r = 0.76). Conclusions: AUC values obtained from CSN analysis reflect image quality and replace the observer detection performance test of image quality.

CT画質や照射線量低減に対し、深層学習をベースとした画像再構成(DLR)がもたらす効果について検討し、歯科インプラント手術における術前画像診断として、低照射線量マルチスライスCT(MDCT)スキャンによるプロトコルを提案した。ヒト頭部モデル下顎ファントムを用いて、読影者評価には、Catphan phantom600とTOSファントムを物理特性分析に用いた。管電圧120kV、管電流120-60mA～40-30mAの条件下で、320列MDCT装置でスキャンし、DLR画像を再構成した。また、120mAで取得し、フィルタ補正逆投影(FBP)法で再構成した画像を参照画像として比較した。なお、再構成処理した画像は、読影者2名により、それぞれ盲検下で4点スケール法で画質を評価した。その結果、管電流40mAで取得しDLRで再構成した画像(40DLR)と、参照プロトコルによる取得画像の画質に有意差はみられなかったが、40DLRで取得した1.0cycles/minでのシステム性能関数(SPF)では、参照プロトコルで取得した画像に比べ、156.7%も改善が得られた。以上の実験結果から、今回提案したDLRプロトコルにより、照射線量が2/3低減することに成功し、歯科インプラント手術に際し、高速スキャンで最小侵襲の術前画像診断として、有用なMDCT画質が得られることが確認された。

Objectives: This study aimed to investigate the impact of a deep learning-based reconstruction (DLR) technique on image quality and reduction of radiation exposure, and to propose a low-dose multidetector-row computed tomography (MDCT) scan protocol for preoperative imaging for dental implant surgery. Methods: The PB-1 phantom and a Catphan phantom 600 were scanned using volumetric scanning with a 320-row MDCT scanner. All scans were performed with a tube voltage of 120 kV, and the tube current varied from 120 to 60 to 40 to 30 mA. Images of the mandible were reconstructed using DLR. Additionally, images acquired with the 120-mA protocol were reconstructed using filtered back projection as a reference. Two observers independently graded the image quality of the mandible images using a 4-point scale (4, superior to reference; 1, unacceptable). The system performance function (SPF) was calculated to comprehensively evaluate image quality. The Wilcoxon signed-rank test was employed for statistical analysis, with statistical significance set at p value < 0.05. Results: There was no significant difference between the image quality acquired with the 40-mA tube current and reconstructed with the DLR technique (40DLR), and that acquired with the reference protocol (3.00, 3.00, p = 1.00). The SPF at 1.0 cycles/mm acquired with 40DLR was improved by 156.7% compared to that acquired with the reference protocol. Conclusions: Our proposed protocol, which achieves a two-thirds reduction in radiation dose, can provide a minimally invasive MDCT scan of acceptable image quality for dental implant surgery.

歯科治療時の異物誤飲・誤嚥は完全に防ぐことができない。異物の物性によっては積極的な摘出にはならず、経過観察とする場合もあるが、その所在を確認する第一選択はX線検査である。パノラマX線撮影などでX線像として見慣れた修復物等なら比較的探しやすいが、器具など撮影対象と想定していないものが対象異物となることもある。の見慣れない歯科関係材料・器具の仮想誤飲・誤嚥時X線画像データベースを構築するとともに、dual energy subtraction等の技術を用いて、どのように描出が変化するかを評価する。

IgG4関連涙腺・唾液腺炎では顎下腺に特徴的な超音波像が認められる。
本研究では顎下腺超音波検査に精通した歯科放射線科中心の多施設で、診断者の標準化の必要性の有無、エラストグラフィやAI診断の導入による診断の簡便化の成否、パワードプラ法での血流の多寡による予後判定の成否などを検討し、顎下腺超音波診断の正診率をより一層向上させ、本邦のみならず、国際的なIgG4-DSの診断基準に非侵襲的な顎下腺超音波検査を導入する基盤を確立することを目的とする。 -

The ultimate goal of the project was to establish the basis for the introduction of sonography into the international diagnostic criteria for Sjogren's syndrome. We tried to achieve quantification/objectivity of the diagnosis through the application of ultrasound elastography.
Elastography images and measurements are affected by the pressure applied. In this study, to keep the pressure applied during examinations within a certain range, we attempted to develop a pressure sensor that can be attached to the probe. Elastic springs, slide resistors, and stainless steel movable plates were connected to a support surface. When the movable plate is moved, the spring extends and the resistance value increases. The amount of change was measured as a voltage by applying a constant voltage to the entire area. The force applied and the display on the digital panel were in a linear relationship. Therefore, the prototype of pressure sensor could be successfully developed. -
