CARE AND PREPARATION
FOR PROCEDURES

preparation for ultrasound

Ultrasound is a diagnostic test that uses ultrasound to evaluate organs or structures in the body. In ultrasound, equipment called an ultrasound machine is used, which together with an instrument called a transducer, emits and receives echoes to and from the area of interest. The echoes received are converted into images suitable to be evaluated by the doctor and help with diagnoses.
