Magnetic resonance imaging (MRI) of the prostate uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within a man’s prostate gland.
It is primarily used to evaluate the extent of prostate cancer and determine whether it has spread. It also may be used to help diagnose infection, benign prostatic hyperplasia (BPH) or congenital abnormalities. Exams may be performed using an endorectal coil – a thin wire covered with a latex balloon – that is inserted a short distance into the rectum.
Prostate MRI does not use ionizing radiation, and it provides images that are more clear and more detailed than other imaging methods.
