The value of dynamic MR imaging for hypointensity lesions of the peripheral zone of the prostate.
The aim was to evaluate the role of dynamic magnetic resonance (MR) imaging for prostatic carcinoma. Forty-two men with clinical suspicion of a prostatic carcinoma underwent MR imaging. Dynamic MR was performed, followed by postcontrast T1-weighted imaging with fat suppression. Histologic diagnosis was 21 prostatic carcinomas (in 19 patients), 21 benign tissues, and 2 chronic prostatitis. The diagnostic accuracy was 75% for T2-weighted images, and 79% for dynamic images. The accuracy of the combination of dynamic MR images with postcontrast T1-weighted images was 82%. It was concluded that dynamic MR imaging was useful in differentiation of low intensity lesions in the peripheral zone.
