Magnetic resonance imaging of the prostate

Twenty-two normal volunteers and 32 patients with either benign prostatic hypertrophy or prostatic carcinoma were examined by magnetic resonance imaging (MRI). The images were of high quality and clearly demonstrated the prostate gland and the surrounding anatomy but were of limited value in differentiating between benign and malignant prostatic disease. Using a specific pulse sequence, the authors were able to visualize what they believed to be the periprostatic venous plexus and suggest that the demonstration of this venous plexus may be of value in showing extraglandular spread of carcinoma of the prostate.
