Ultrasound imaging, also called ultrasound scanning or sonography, involves imaging various parts of the body with high-frequency sound waves that produce pictures of the inside of the body. Ultrasound examinations are painless and do not use ionizing radiation (as used in x-rays or CT scans). Ultrasound images are captured in real-time and can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels and internal organs.

Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Conventional ultrasound displays the images in thin, flat sections of the body. Ultrasound exams are typically requested to evaluate the organs inside the abdomen (most frequently the liver, gallbladder or kidneys), the blood vessels of the neck or abdomen, fluid within various regions of the body as well as evaluation of structures such as the breast, scrotum/testicles, thyroid gland and other portions of the body. Ultrasound can also be used to guide a needle biopsy where the radiologist places a small needle into a portion of the body utilizing ultrasound’s real time viewing capabilities. Most ultrasound exams take about 15-30 minutes to complete.
