What is an Ultrasound Scan?

 Also called sonography or ultrasonography, this extremely accurate diagnostic imaging procedure uses sound waves to produce images of soft tissues which can not be duplicated with x-ray.

A sound wave passes into the body and strikes various organs sending back echoes which are interpreted by a transducer, a hand held instrument placed against the body and passed over a specific area during the exam.

Transducers are placed inside the body for some exams, such as the endovaginal test where a transducer slightly larger than a tampon is inserted into the vagina.

How do I prepare for an ultrasound?

Before certain exams, your physician may ask you to drink fluids or to empty your bladder. Avoid gas-producing foods for 1-2 days prior to the exam. No other preparation is needed.
