Definition

A pelvic (transabdominal) ultrasound is an imaging test. It is used to examine organs in the pelvis.

How the Test is Performed

During the procedure, you will lie on your back on the table. Your health care provider will apply a clear gel on your abdomen.

Your provider will place a probe (transducer), over the gel, rubbing back and forth across your belly:

  • The probe sends out sound waves, which go through the gel and reflect off body structures. A computer receives these waves and uses them to create a picture.
  • Your provider can see the picture on a TV monitor.

Depending on the reason for the test, women also may have a transvaginal ultrasound during the same visit.

How the Test will Feel

The test is painless and easy to tolerate. The conducting gel may feel a little cold and wet.

How to Prepare for the Test

A pelvic ultrasound may be done with a full bladder. Having a full bladder can help with looking at organs, such as the womb (uterus), within your pelvis. You may be asked to drink a few glasses of water to fill your bladder. You should wait until after the test to urinate.

Normal Results
