The Magnetic Resonance Imaging (MRI) of the pelvis is a painless and simple procedure that provides excellent images of pelvic area including bladder, reproductive organs such as the uterus and ovaries in females and the prostate gland in males, blood vessels and lymph nodes. There are many indications for this test including tumours in the ovaries, uterus, prostate, rectum, and anus. It also can be used to look for an anal fistula which is a tube-shaped passage from the anal canal to a hole in the skin near the anus and look for the cause of pelvic pain in women, such as endometriosis.
