Ultrasound uses reflected sound waves to image inside the body. Similar to an echo from a canyon wall, the ultrasound machine sends out high-frequency and inaudible sound waves that reflect off body structures. A computer receives the reflected waves and reconstructs images of tissues and fluid. This exam uses no radiation.
A small handheld transducer that both sends and receives the sound waves will be placed against your body in the area to be imaged. You may be asked to change your position depending on the area being examined.
Preparation for the procedures will depend on the body region being examined.
