Ultrasound is a diagnostic test that uses high-frequency sound waves instead of radiation to create images of structures in your body including organs, blood vessels, and soft tissues. Because there is no radiation exposure, ultrasound is the preferred imaging method for monitoring the progress of a pregnancy, but it can also be used to identify and diagnose conditions impacting soft tissues and organs in the body.
Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is usually a painless medical test and can be used for a wide variety of studies, including breast, abdominal, pelvic, obstetric, arterial, venous and cardiac. Breast ultrasound is non-invasive and often used as a follow-up test after an abnormal finding on a mammogram or other breast exam.
