When is magnetic resonance imaging (MRI) used in prostate screening?

Marc B. Garnick, MD
Hematology & Oncology
The magnetic resonance imaging (MRI) exam is not used for routine prostate screening, but it can be helpful in certain situations. For example, if the prostate-specific antigen (PSA) -- proteins made by cells in the prostate -- continues to rise but a biopsy doesn't detect cancer, MRI may pinpoint a suspicious area for a more targeted biopsy. It can also help show tumors in the front of the prostate, the size and stage of a tumor, and whether it has spread beyond the gland. If cancer is diagnosed, MRI may offer guidance about where to target radiation therapy.
