Pelvic Ultrasound and Pelvic MRI

Pelvic Ultrasound

Ultrasound, also called “sonography”, is a technique that uses sound waves to map out targeted areas of the body. This map creates an image that your radiologist can use to detect tissue abnormalities, rule out or diagnose disease, and even check up on the health of a growing baby inside the womb. Ultrasound is safe and painless. Your physician may apply ultrasound gel to the skin prior to the procedure. Then a wand is used, gently gliding across the skin over the area in question, and at the same time transmitting the image to a monitor for viewing.

Why is Pelvic Ultrasound Used?

Women and Men:

  • Detect and monitor unnatural growths or lumps in the pelvic area.
  • View the bladder, kidneys and determine the cause of blood in the urine.
  • Diagnose other urinary problems.
  • Detect or monitor colorectal cancer.


  • Investigate the cause of irregular bleeding or pain such as endometriosis.
  • Measure the size of the ovaries and uterus, or the length of the cervix.
  • Confirm pregnancy and rule out ectopic pregnancy.
  • View uterine fibroids.


  • Detect prostate cancer.
  • View and check prostate.

Pelvic MRI

In some cases, a Pelvic MRI may be advised by your physician in addition to or as a replacement for ultrasound. MRI (Magnetic Resonance Imaging) uses radio waves and a magnetic field to create images of the pelvic area for your radiologist to view and use as a diagnostic tool. MRI is a safe and painless procedure, lasting less than an hour in most cases. An IV contrast agent may be administered prior to the procedure to enhance visualization.

Why is Pelvic MRI Used?

Pelvic MRI is used for the same diagnostic purposes as ultrasound, however MRI offers more detail. Therefore, your physician may recommend a pelvic MRI procedure if the results of an ultrasound or other tests were inconclusive, or in the case that more detailed information is needed about your case. In addition to that, MRI is especially useful in use on post-menopausal women.
