BACKGROUND: Limited data are available regarding the role of magnetic resonance imaging (MRI), particularly the new generation 3 Tesla technology, and especially diffusion-weighted imaging (DWI) in predicting @entity1575 . The aim of our pilot study was to assess the clinical performance of the apparent diffusion coefficient (ADC) of liver parenchyma for the assessment of @entity1575 in @entity1 with @entity1561 ( @entity1561 ). METHODS: 18 @entity1 with biopsy-proven @entity1561 underwent DWI with 3 Tesla MRI. DWI was performed with single-shot echo-planar technique at b values of 0-500 and 0-1000 s/mm(2). ADC was measured in four locations in the liver and the mean ADC value was used for analysis. Staging of @entity82 was performed according to the METAVIR system. RESULTS: The median age of @entity1 was 52 years (range 23-73). The distribution of @entity1 in different @entity82 stages was: 0 (n=1), 1 (n=7), 2 (n=1), 3 (n=5), 4 (n=4). @entity82 stage was poorly associated with ADC at b value of 0-500 s/mm(2) (r= -0.30, P=0.27). However it was significantly associated with ADC at b value of 0-1000 s/mm(2) (r= -0.57, P=0.01). For this b value (0-1000 s/mm(2)) the area under receiver-operating characteristic curve was 0.93 for @entity82 stage >= 3 and the optimal ADC cut-off value was 1.16 *10(-3) mm(2)/s. CONCLUSION: 3 Tesla DWI can possibly predict the presence of advanced @entity82 in @entity1 with @entity1561 .
