Ultrasound (Sonogram)

Ultrasound imaging & 3D ultrasound imaging in St. Louis


Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small probe and ultrasound gel placed directly on the skin. High-frequency sound waves are transmitted from the probe through the gel into the body. The probe collects the sounds that bounce back and a computer then uses those sound waves to create an image. Ultrasound examinations do not use ionizing radiation (as used in x-rays), thus there is no radiation exposure to the patient. Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.  Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions.  Conventional ultrasound displays the images on computer monitors for interpretation by a radiologist.  We have the most advanced ultrasound technology including three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images.
