Principles of Ultrasound
Ultrasound is the most common and first-line imaging study performed in the genitourinary tract in children. It is used for screening and monitoring children even before birth. We provide a primer for the reader to understand the pertinent physics of ultrasonography by reviewing the physical properties of sound waves and their ability to capture images. Artifacts created by these physical properties are sometimes of diagnostic utility. The indications for performing ultrasound studies are described followed by a discussion of the technique and expected finding of normal ultrasound studies of the kidney, bladder, and testis in children.
