Ultrasound Info

See "pre-register" link for prep and consent information

An ultrasound test is a radiology technique, which uses high-frequency sound waves without radiation to produce images of the organs and structures of the body. The sound waves are sent through body tissues with a wand-like device called a transducer.  Ultrasound examinations can be used in various areas of the body for a variety of purposes. These purposes include examination of the chest, abdomen, blood vessels (such as to detect blood clots in leg veins) and the evaluation of pregnancy.

HOW IS THE PROCEDURE PERFORMED

The transducer is either placed directly on top of the skin, which has a gel applied to the surface or inside the vagina for more detailed imagery. The sound waves that are sent by the transducer through the body are then reflected by internal structures as "echoes." These echoes return to the transducer and are transmitted electrically onto a viewing monitor.  The echo images are then recorded on a plain film and can also be recorded on videotape.

Who interprets the results and how do I get them?

NWDC Diagnostic Imaging has an agreement with a group of board-certified radiologists to facilitate our procedures and interpret the results.  A diagnostic report will be sent to your doctor within forty-eight (48) hours of your procedure.  In the event of an abnormal test result, the radiologist will contact your doctor's office by telephone.

PREPARING FOR THE PROCEDURE

Preparation for ultrasound is minimal. Generally, if internal organs such as the gallbladder are to be examined, patients are requested to avoid eating and drinking with the exception of water for six to eight hours prior to the examination. This is because food causes gallbladder contraction, minimizing the size, which would be visible during the ultrasound. In preparation for examination of the baby and womb during pregnancy, it is recommended that mothers drink at least four to six glasses of water approximately one to two hours prior to the examination for the purpose of filling the bladder. The extra fluid in the bladder moves air-filled bowel loops away from the womb so that the baby and womb are more visible during the ultrasound test.
