Early and accurate diagnosis of prostate cancer (Pca) recurrence is very important. Some modalities have been used in the diagnosis of Pca recurrence such as PET, MRS and PWI. We also though that DWI and ADC should play their roles in this field. The purpose of this study is to investigate the difference of ADC values between recurrent and non-recurrent Pca after endocrinotherapy. Twenty-eight Pca patients with or without cancer recurrence were recruited and the ADC values of recurrent and non-recurrent regions were measured. Statistically significant difference could be detected between them.
