Assessment of XXXX with Diffusion-Weighted Magnetic Resonance Imaging Using Different b-values in @entity3619 .

@entity1575 @entity1 @entity3619 @entity202
OBJECTIVE: To examine the effectiveness of apparent diffusion coefficient (ADC) values and to compare the reliability of different b-values in detecting and identifying significant @entity1575 . SUBJECTS AND METHODS: There were 44 @entity1 with @entity3619 ( @entity3619 ) in the study group and 30 healthy @entity1 in the control group. Diffusion-weighted magnetic resonance imaging (DWI) was performed before the liver biopsy in @entity1 with @entity3619 . The values of ADC were measured with 3 different b-values (100, 600, 1,000 s/ @entity202 ). In addition, @entity1575 was classified using the modified Ishak scoring system. @entity1575 stages and ADC values were compared using areas under the receiver-operating characteristic (ROC) curve. RESULTS: The study group's mean ADC value was not statistically significantly different from the control group's mean ADC value at b = 100 s/ @entity202 (3.69    0.5 * 10-3 vs. 3.7    0.3 * 10-3 @entity202 /s) and b = 600 s/ @entity202 (2.40    0.3 * 10-3 vs. 2.5    0.5 * 10-3 @entity202 /s). However, the study group's mean ADC value (0.99    0.3 * 10-3 @entity202 /s) was significantly lower than that of the control group (1.2    0.1 * 10-3 @entity202 /s) at b = 1,000 s/ @entity202 . With b = 1,000 s/ @entity202 and the cutoff ADC value of 0.0011 @entity202 /s for the diagnosis of @entity1575 , the mean area under the ROC curve was 0.702    0.07 (p = 0.0015). For b = 1,000 s/ @entity202 and the cutoff ADC value of 0.0011 @entity202 /s to diagnose significant @entity1575 (Ishak score = 3), the mean area under the ROC curve was 0.759    0.07 (p = 0.0001). CONCLUSION: Measurement of ADC values by DWI was effective in detecting @entity1575 and accurately identifying significant @entity1575 when a b-value of 1,000 s/ @entity202 was used.
