What Is a Prostate MRI?

A prostate MRI can help find tumors because they act differently than normal tissue. It uses a combination of non-contrast and dynamic contrast enhanced MRI. Contrast is injected though an IV, and the exam measures how your body absorbs it. Most exams take 45 minutes at most. 

Contrast helps improve the clarity of images to make a more accurate diagnosis. The benefits of using contrast typically outweigh any potential risk. We carefully asses your risk before giving you contrast.
