We evaluated the ability of color Doppler ultrasound to improve the sensitivity of compression ultrasound in the detection of asymptomatic DVT in high-risk orthopedic patients. Ultrasound uses a transducer that emits ultrasonic sound waves that bounce off the organs like an echo and return to the transducer, converting the echo into an electronic image of the organs. Prevention and treatment information (HHS). 1993 Mar;23 Suppl 1:61-71. doi: 10.1159/000216911. During a Doppler ultrasound, a technician trained in ultrasound imaging (sonographer) presses a small hand-held device (transducer), about the size of a bar of soap, against your skin over the area of your body being examined, moving from one area to another as necessary.

A single copy of these materials may be reprinted for noncommercial personal use only. • More sensitive than color flow (not clear why, potentially due to frame averaging). Color Doppler ultrasonography does not increase the detection rate for asymptomatic DVT over compression ultrasound and thus cannot be recommended as a screening test in this setting. Perform a complete duplex ultrasound exam of the cervical carotid and vertebral artery system; record and present all measurements of image and Doppler data. The CT is a modality that sends x-rays to the body every time the scanner rotates and so the x-ray image is taken. 76700 Ultrasound, abdominal, real time with image documentation; complete. The echo, usually 2 dimensional, just takes images of the heart structures and valve mobility. Another functional form of ultrasound is elastography, a method for measuring and displaying the relative stiffness of tissues, which can be used to differentiate tumors from healthy tissue.
