About Testicular Ultrasounds
Ultrasound is frequently used to diagnose lumps and pain originating in the scrotum. Testicular ultrasound, also referred to as scrotal ultrasound, is safe and pain free. Unlike x-ray and computed tomography (CT), ultrasound does not expose the body to radiation. Since there is no bowel or fat accumulation---two factors that hinder ultrasound---in the scrotum, high-frequency ultrasound can be used to obtain images of the greatest detail. Ultrasound is considered to be the gold standard for scrotal imaging.

Preparation
-
No preparation is necessary preceding the exam. Once you arrive at the ultrasound room, you will be asked to undress. Many sonographers use several towels for patient position. One is used to hold the penis against the belly---out of the way. Another is used to rest to scrotum on, creating a flat surface for the camera. Another may be used as a general cover.
Procedure
-
Warm gel will be placed on the scrotum. The sonographer will use a small, hand-held camera to acquire a series of images of both testicles. After the general images are acquired, you may be asked to indicate where the pain or lump is.
Results
-
In most health-care facilities, the sonographer cannot give you any results. The ultrasound will be read by a radiologist, who will dictate a report. The report will be sent to your doctor within a few days.
