Ultrasonic B-scan echoarteriographic imaging of experimentally induced thrombi in dogs. 1979

L N Sekhar, and J F Wasserman, and J van der Bel-Kahn, and C P Olinger

Ultrasonic echoarteriography is a noninvasive method of visualizing extracranial arteries in health and disease. The real-time echoscanning device developed at the University of Cincinnatti utilizes a 5-MHz (center frequency) pulse-echoimaging system. B-mode pictures of the tissues studied are obtained and displayed on a video screen, real-time operation being provided by the scanning mechanism operating at 30 frames per second. In our experiments internal arterial damage produced by surgically scraping the intima induced experimental thrombosis in nine carotid in nine carotid and three femoral arteries in dogs. Where pathologically demonstrated, the thrombi were demonstrated by ultrasonic echoarteriography in every instance. Echoarteriography seemed more sensitive than contrast arteriography in the detection of a partially occlusive thrombus.

UI	MeSH Term	Description	Entries
D002341	Carotid Artery Thrombosis	Blood clot formation in any part of the CAROTID ARTERIES. This may produce CAROTID STENOSIS or occlusion of the vessel, leading to TRANSIENT ISCHEMIC ATTACK; CEREBRAL INFARCTION; or AMAUROSIS FUGAX.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.

D014465	Ultrasonics	A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.	Ultrasonic
