Ultrasound

Ultrasonography, which is sometimes called sonography, uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood blow through various vessels. Ultrasound procedures are often used to examine many parts of the body such as the abdomen, breasts, female pelvis, prostate, scrotum, thyroid and parathyroid, and the vascular system. During pregnancy, ultrasounds are performed to evaluate the development of the fetus.

Having a successful exam

Ultrasound exams of the pelvic area require that you have a full bladder at the beginning of the exam.  Ultrasound uses sound waves to image parts of the body. A warm gel is applied to the probe and pressed into the skin near the area of interest. You may need to change into a gown or lift, remove clothing covering the skin in the area of interest.

Exam Preparation

Please wear comfortable clothing. Avoid wearing pants with metal snaps, zippers, or belts. If you must, then you will be required to change into a gown prior to the exam.  Certain exams require specific preparation such as refraining from eating or coming with a full bladder.  The SDI scheduler will let you know if you have such a preparation which is essential to obtaining an optimal exam.
