Materials and Methods: We prepared solutions of 3 different ytterbium-based PARACEST agents at concentrations of 5, 10, 20, and 50 mM at a pH of 7.4 and at a concentration of 50 mM at pHs of 3.0, 5.0, 7.4, and 9.5. We acquired images with a turbo spin echo technique using a quadrature head coil and a clinical 3.0-tesla MR system in accordance with the safety limits of the specific absorption rate (SAR). We acquired CEST images with presaturation offset frequencies from -5,000 Hz (-39.1 ppm) to 5,000 Hz (39.1 ppm) with an interval of 500 Hz (3.9 ppm) for each condition. We repeated each scan 3 times and then calculated the mean and standard deviations of the magnitude of the CEST effect at different concentrations and pH values for each agent. We used one-way analysis of variance and Tukey's honestly significant difference post hoc test to compare mean values of the magnitude of the CEST effect obtained at different concentrations and pH values. P < 0.05 was considered significant.
Results: PARACEST agents showed a strong CEST effect at their specific presaturation offset frequencies. For each agent, the CEST effect showed significant concentration dependency (P < 0.05), increasing with agent concentration, and significant pH dependency (P < 0.05), with strong effect near physiological pH.
Conclusion: CEST imaging using ytterbium-based PARACEST agents might be feasible on a clinical MR scanner with further modifications, such as adjustments of the presaturation radiofrequency pulse and imaging protocols..

MATERIALS AND METHODS: This retrospective study consisted of 55 and 33 patients who underwent SPIO- and Gd-EOB-DTPA-enhanced MRI in addition to (99m)Tc-GSA scintigraphy, respectively. For each patient, we calculated Pre R2* and Pre R2, which are equivalent to R2* (=1/T2*) and R2 (=1/T2) values of the liver parenchyma; ΔR2* and ΔR2, which represent differences in R2* and R2 values of the liver parenchyma before and after administration of SPIO; and the increase rates of both the liver-to-spleen signal intensity ratio (LSR) and the liver-to-major psoas muscle signal intensity ratio (LMR) on the hepatobiliary phase compared with the precontrast image. For (99m)Tc-GSA scintigraphy, the receptor index LHL15 and the blood clearance index HH15 were recorded.
RESULTS: Regression analysis showed a moderate correlation between Pre R2* and LHL15 (P<0.05). Mild to moderate correlations were also obtained between any combination of ΔR2* and ΔR2 on the one hand, and LHL15 and HH15 on the other (P<0.05). There were moderate correlations between any combination of increase rates of LSR and LMR on the one hand, and LHL15 and HH15 on the other (P<0.05-0.001).
CONCLUSION: Pre R2*, ΔR2*, ΔR2 and the increase rates of LSR and LMR could be used as quantitative indicators of liver function.

Tsushima H, Okazaki K, Takayama Y, Hatakenaka M, Honda H, Izawa T, Nakashima Y, Yamada H, Iwamoto Y., Evaluation of cartilage degradation in arthritis using T1ρ magnetic resonance imaging mapping., Rheumatol International, 2011.09, T1ρ magnetic resonance imaging (MRI) can be used to map proteoglycan (PG) loss in cartilage. Here, we used T1ρ MRI to map cartilage degradation in osteoarthritis (OA) and rheumatoid arthritis (RA). Tissue samples were obtained from five RA patients and 14 OA patients following total knee arthroplasty (TKA). Three parameters were measured: First, macroscopic grading of cartilage sample tissues was performed on a 5-grade scale (G0: normal, G1: swelling, G2: superficial fibrillation, G3: deep fibrillation, G4: subchondral bone exposure). Second, semi-quantitative values of PG were assessed by measuring the optical density of Safranin-O-stained paraffin sections that had been digitally photographed. Third, cartilage was divided into superficial and deep layers and the T1ρ values were quantified. T1ρ values of OA and RA in the superficial layers showed significant differences between groups (G0/1 and G0/2 for OA; G0/2 and G1/2 for RA). In the deep layers, T1ρ values of OA and RA also differed significantly between groups. In both the superficial and deep layers, there was a significant correlation between the mean T1ρ values and macroscopic grading (P < 0.01 for OA, P < 0.001 for RA). We found a negative correlation between the score of Safranin-O staining and T1ρ values (r = -0.61 for OA, r = -0.79 for RA). In addition, RA subjects had significantly higher T1ρ values than OA subjects of similar morphologic grade. In conclusion, T1ρ MRI is able to detect and map the early stages of cartilage degradation in OA and RA. This method is reliable and useful for the evaluation of macromolecular changes in arthritic cartilage..

MATERIALS AND METHODS: A total of 25 knees in 11 men and 12 women with knee injuries were imaged using whole knee joint proteinCEST MRI sequence at 3 T. The joint synovial fluid was segmented and the asymmetric magnetization transfer ratio at 3.5 ppm MTR(asym) (3.5 ppm) was calculated to assess protein content in the synovial fluid. The 85th percentile of synovial fluid MTR(asym) (3.5 ppm) distribution profile was compared using the independent Student's t test. The diagnostic performance of the 85th percentile of synovial fluid MTR(asym) (3.5 ppm) in differentiating OA and non-OA knee joints was evaluated.
RESULTS: The 85th percentile of synovial fluid MTR(asym) (3.5 ppm) in knee joints with OA was 8.6%±3.4% and significantly higher than that in the knee joints without OA (6.3%±1.4%, P<.05). A knee joint with an 85th percentile of synovial fluid MTR(asym) (3.5 ppm) greater than 7.7% was considered to be an OA knee joint. With the threshold, the sensitivity, specificity and overall accuracy for differentiating knee joints with OA from the joints without OA were 54% (7/13), 92% (11/12) and 72% (18/25), respectively.
CONCLUSION: proteinCEST MRI appears feasible as a quantitative methodology to determine mobile protein levels in synovial fluid and identify patterns characteristic for OA disease.

T1ρマップを用いて肝機能障害を評価できるか検証すること。
【方法】
健常男性9名(平均年齢=31.4才)、肝腫瘍を有するもしくは疑われた患者43名(男/女=25/18、平均年齢=64.8才)を対象とした。肝臓T1ρマップはフィリップス社製3TMRI装置で、32ch Torso Cardiac Coilを用い横断像で撮像した。Time of spin lock pulse(TSL)は1,10,20,40,80msを使用し、ブロック波にて照射した。T1ρマップは自作ソフトを用いて計算した。T1ρマップはα)TSL=1,10,20,40msとβ)TSL=1,10,20,80msの、それぞれのTSLより撮影した画像を用いて2種類作成した。肝実質のT1ρ値計測は、マップ上に脈管組織を含まないように関心領域を3箇所設定した後に、平均値と標準偏差を算出した。各患者の肝機能は、画像所見及びMRI撮影前後1週間以内の血液検査データを用いてChild-Pugh分類を用いて判定した。対象を病歴や肝機能評価に応じて、a)健常者、b)Child-Pugh分類Aで慢性肝障害の病歴なし、c)Child-Pugh分類Aで慢性肝障害の病歴あり、d)Child-Pugh分類 B,Cに分類した。各グループの平均T1ρ値は一元配置分散分析と Tukey HSD ポストホックテストを用いて比較し、T1ρマップと肝機能の関係を検証した。また、2種のマップ間でも平均T1ρ値をpaired t-testを用いて対比した。
【成績】
各グループの対象者数はa)9名、b)8名、c)22名、d)13名であった。平均T1ρ値と標準偏差は、方法α)のT1ρマップではa)35.5±2.7ms、b)41.5±4.5ms、c)41.8±5.0ms、d)44.2±6.2msであった。方法β)のT1ρマップではa)41.6±1.7ms、b)46.7±4.3ms、c)47.0±4.4ms、d)49.8±6.1msであり、肝機能障害が進行するにつれ、T1ρ値は上昇する傾向が見られた。平均値の比較では、方法α)とβ)いずれにおいても、a)とc)およびa)とd)の間に有意差を認めたが(p<0.05)、他の2群間には有意差はなかった。また、方法α)とβ)いずれでも同様の結果が得られたが、両者の平均T1ρ値には有意差が認められた(p<0.05)。
【結論】
T1ρマップは肝機能の評価に利用できる可能性がある。.
