Ultrasound imaging (Sonography) is a safe and painless study that uses high-frequency sound waves to produce pictures of soft tissues, such as muscles and internal organs. During your examination, a hand-held device (transducer) sends out sound waves that bounce off of various body structures. The returning sound waves, or echoes, are recorded by a sensitive microphone in the transducer and changes in pitch/direction are displayed as real-time images on a monitor. These live images are usually recorded on videotape and one or more frames of the moving pictures are typically captured as still images.
*Note* There is zero radiation exposure with this test.
Doppler ultrasound, a more specific ultrasound application, measures the direction and speed of blood cells as they move through vessels. The movement of blood cells causes a change in pitch of the reflected sound waves, which is known as the Doppler Effect. A computer collects and processes the sounds and creates images that represent the flow of blood through the blood vessels.
Most people associate ultrasound with a pregnancy, but it is commonly used for diagnosing diseases of the thyroid, abdomen and pelvis, as well as vascular abnormalities. When you have an ultrasound, the test is used to visualize muscles, tendons, and many internal organs with respect to their size, structure, and any pathological lesions with real time tomographic images.
Preparation: Be sure to wear comfortable, loose-fitting clothing. You will need to remove clothing and jewelry in the area that is being examined. You also may be asked to wear a gown during the procedure. For some scans, doctors may instruct patients not to eat or drink for as many as 12 hours before their appointment. For other scans, you may be asked to drink up to six glasses of water two hours prior to your exam and avoid urinating so that your bladder is full when the scan begins.
