PURPOSE:To investigate the diagnostic accuracy of 3.0-T diffusion-weighted imaging (DWI) for detection of prostate cancer by using different b-values.
METHODS: Seventy-three patients underwent magnetic resonance imaging (MRI) at 3.0 T. Three MRI sets were reviewed by two radiologists: MRI and DWI (b=500s/mm2) (protocol A), MRI and DWI (b=1000s/mm2) (protocol B), and MRI and DWI (b=2000s/mm2) (protocol C). Areas under the receiver operating characteristic curve (AUCs) were calculated.
RESULTS:The mean of the AUCs in protocol C was larger than those in protocol A and in protocol B (P< .05).
CONCLUSION: DWI (b=2000s/mm2) at 3.0 T can improve the diagnostic accuracy for detection of prostate cancer.
