The apparent diffusion coefficient (ADC) value, image quality and diagnostic performance of diffusion-weighted imaging (DWI) of the prostate at 3 T were compared with those at 1.5 T in forty patients. The ADC values at 3 T were almost equivalent to those at 1.5 T, and statistically significant correlation was seen between them. Image quality of DWI at 3 T was significantly superior to that at 1.5 T. Diagnostic performance of DWI at 3 T was superior to that at 1.5 T, but the difference was not significant.
