| ultrasonography, doppler, duplex | Ultrasonography applying the doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the doppler shift frequency. (12 Dec 1998) |
|---|---|
| ultrasonography, doppler, pulsed | Ultrasonography applying the doppler effect, with velocity detection combined with range discrimination. Short bursts of ultrasound are transmitted at regular intervals and the echoes are demodulated as they return. (12 Dec 1998) |
| ultrasonography, doppler, transcranial | A non-invasive technique using ultrasound for the measurement of cerebrovascular haemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum. (12 Dec 1998) |
| foetal doppler study | <radiology> Non-stress test (NST), external monitoring for 20 minutes; poor specificity, greater than4 foetal heart accelerations (greater than15 bpm over baseline for 15 seconds) following foetal movement in foetus greater than34 weeks, no heart accelerations in immaturity, sleep, maternal sedation contraction stress test (CST), external monitoring after oxytocin or maternal breast stimulation, greater than 3 uterine contraction in 10 minutes; 50% specificity uterine and umbilical artery waveform, elevated systolic:diastolic ratio = increased vascular resistance foetal aortic flow volume, 185-246 ml/kg/min see also: biophysical profile, intrauterine growth retardation (IUGR) (12 Dec 1998) |
| laser-doppler flowmetry | A method of non-invasive, continuous measurement of microcirculation. The technique is based on the values of the doppler effect of low-power laser light scattered randomly by static structures and moving tissue particulates. (12 Dec 1998) |
| artery, carotid | A key artery located in the front of the neck that carries blood from the heart to the brain. (12 Dec 1998) |
| basal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the base of the tentorium. Synonym: ramus basalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| ganglionic branch of internal carotid artery | <anatomy, artery> Branch to trigeminal ganglion; a small branch of the cavernous part of the internal carotid artery to the trigeminal ganglion. Synonym: ramus ganglii trigeminalis. (05 Mar 2000) |
| marginal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the free margin of the tentorium. Synonym: ramus marginalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| carotid | Pertaining to the carotid artery. (12 Dec 1998) |
| carotid arteries | <anatomy> Paired large calibre vessels that pass on either side of the neck supplying oxygenated blood to the brain. Occlusive disease (atherosclerosis) of the vessels can lead to stroke. (27 Sep 1997) |
| carotid artery | <anatomy, artery> A key artery located in the front of the neck that carries blood from the heart to the brain. Cholesterol plaques on the inner wall of the carotid artery can lead to stroke. (12 Dec 1998) |
| carotid artery bruit | <radiology> Differential diagnosis: Atherosclerotic plaque or stenosis in common carotid artery or major vessels., Normal vessel. Asymptomatic bruits are a risk factor for stroke, and 75% of strokes occur in the carotid circulation. The majority of patients with bruits will have stenosis of 50% or more. The vast majority (90%) of strokes occur without prior symptoms. REF: MacNeil BJ, Abrams HL. Brigham and Women's Hospital Handbook of Diagnostic Imaging. Chapter 27. (12 Dec 1998) |
| carotid artery, common | The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (carotid artery, external) and internal (carotid artery, internal) carotid arteries. (12 Dec 1998) |
| carotid artery, external | Branch of the common carotid artery which supplies the exterior of the head, the face, and the greater part of the neck. (12 Dec 1998) |
