Ultrasound
An ultrasound or sonogram is a safe and painless test utilizing sound waves to produce images of the internal structures of the body. A clear, non-staining gel is applied to the skin. Sound waves are transmitted and received by a transducer moved back and forth over the area being examined.
Ultrasound can also be used to examine other parts of the body including the abdomen, pelvis, prostate, scrotum, thyroid, parathyroid and vascular system. It is frequently used to evaluate fetal growth and movement during pregnancy, and to determine the due date of a baby.
