DCE-MRI is widely used for cancer detection, and is a part of PIRADS v2 guideline for scoring prostatic lesions. Diagnostic accuracy of DCE-MRI may depend on the rate of temporal sampling. In this study we have investigated the relationship between the rate of temporal sampling of DCE-MRI and the accuracy of detection of prostatic carcinoma. We have acquired and analyzed DCE-MRI data from 15 patients. Our results show that the accuracy of DCE-MRI in detection of prostatic carcinoma is not affected by sampling rates between 3.4 to 13.6 seconds.
