Doppler color imaging. Carotid and vertebral arteries. 1992

E I Bluth, and C R Merritt

Duplex sonography and DCI have now become standard modalities for imaging of the extracranial carotid and vertebral arteries. They are equivalent in accuracy to arteriography in the evaluation of flow-limiting stenosis. In addition, the newest scanners all appear to have high-resolution imaging systems capable of characterizing plaque properly. DCI currently leads to more rapid scanning and greater ease in evaluating more difficult patients. The most important advance with DCI will come in the future, when there is better understanding of the significance of the Doppler color-flow patterns now being observed. At present, duplex sonography and DCI remain the only imaging modalities that can evaluate the complete spectrum of abnormalities of the extracranial carotid and vertebral vessels, from minimal stenosis to complete occlusion. As a result, they are valuable tools in the diagnosis of disease.

UI	MeSH Term	Description	Entries
D002339	Carotid Arteries	Either of the two principal arteries on both sides of the neck that supply blood to the head and neck; each divides into two branches, the internal carotid artery and the external carotid artery.	Arteries, Carotid,Artery, Carotid,Carotid Artery
D002537	Intracranial Arteriosclerosis	Vascular diseases characterized by thickening and hardening of the walls of ARTERIES inside the SKULL. There are three subtypes: (1) atherosclerosis with fatty deposits in the ARTERIAL INTIMA; (2) Monckeberg's sclerosis with calcium deposits in the media and (3) arteriolosclerosis involving the small caliber arteries. Clinical signs include HEADACHE; CONFUSION; transient blindness (AMAUROSIS FUGAX); speech impairment; and HEMIPARESIS.

D003116	Color	The visually perceived property of objects created by absorption or reflection of specific wavelengths of light.	Colors
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
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
D014711	Vertebral Artery	The first branch of the SUBCLAVIAN ARTERY with distribution to muscles of the NECK; VERTEBRAE; SPINAL CORD; CEREBELLUM; and interior of the CEREBRUM.	Vertebral Arteries,Arteries, Vertebral,Artery, Vertebral
D016893	Carotid Stenosis	Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX).
