Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses low power sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and directing treatment for a variety of diseases and conditions. Gel is applied to your skin over the area being examined. A trained technician (sonographer) presses a small, hand-held device (transducer) against the area being studied and moves it as needed to capture the images. The transducer sends sound waves into your body, collects the ones that bounce back and sends them to a computer, which creates the images. When your exam is complete, a radiologist analyzes the images and sends a report to your doctor. Your doctor will share the results with you. You should be able to return to normal activities immediately after an ultrasound.
