Ultrasound or sonography involves the transmission of sound waves into the body. Those sound waves are reflected off the internal organs. The reflections are then recorded by special instruments that subsequently create an image of anatomic parts. No ionizing radiation (x-ray) is involved in ultrasound imaging.
For women, pelvic ultrasound is most often used to examine the uterus and ovaries and, during pregnancy, to monitor the health and development of the embryo or fetus. In men, a pelvic ultrasound usually focuses on the bladder and the prostate gland. Ultrasound images are captured in real-time, so they can show movement of internal tissues and organs, such as the flow of blood in arteries and veins.
Pelvic Ultrasound Preparation
These instructions are IMPORTANT. Please follow them.
- You should wear comfortable, loose-fitting clothing for your ultrasound exam.
- For transabdominal imaging of the pelvis, you will be asked to drink up to six glasses of water one hour prior to your exam, so that your bladder is full when the scan begins. A full bladder helps with visualization of the uterus, ovaries and bladder wall. For transvaginal examinations, no bladder filling is required.
- Please let us know before your exam begins if you may be pregnant.
