Assessment of MR angiography versus arteriography for evaluation of cervical carotid bifurcation disease.
PURPOSE To assess the accuracy of MR angiography alone in screening for vascular stenosis of the common carotid bifurcation. METHODS Two hundred two common carotid bifurcations in 101 patients were evaluated with MR angiography and selective contrast arteriography. A two-dimensional time-of-flight pulse sequence was used to obtain sequential transverse images through the common carotid bifurc...
متن کاملMorphological variation of carotid artery bifurcation level in digital angiography.
Knowing of the level of carotid artery bifurcation (CB) is important for vascular surgery in the neck, radical neck dissections, carotid sinus baroreceptor stimulation, catheterisations, and aneurysms. The aim of this study was to determine the CB level in relation with the cervical vertebral levels, compare them on the right and the left sides, and investigate the relation of CB level with the...
متن کاملContrast-enhanced MR angiography of the carotid and vertebrobasilar circulations.
BACKGROUND AND PURPOSE Contrast-enhanced MR angiography (CE MRA) is a proven diagnostic tool in evaluation of the carotid arteries; however, few studies have addressed its accuracy in the vertebrobasilar system. The purpose of this study was to assess the sensitivity and specificity of CE MRA compared with digital subtraction angiography (DSA) for detection of vertebrobasilar disease. METHODS...
متن کاملMR angiography of an aberrant internal carotid artery.
Pulsatile tinnitus with or without a vascular-appearing retrotympanic mass has a number of possible causes (1]. Previous reports (1-4] have stressed the use of CT for evaluation when the masses are vascular appearing. In addition, Remley et al. [1] concluded that MR imaging has only a secondary role in the evaluation of pulsatile tinnitus because it cannot detect vascular variants such as an ab...
متن کامل3DFT MR angiography of carotid and basilar arteries.
Three-dimensional Fourier transform (3DFT) time-of-flight and two-dimensional Fourier transform (2DFT) projection phase-contrast MR angiography was performed in eight healthy volunteers and in 14 patients with known carotid artery or basilar artery occlusion, stenosis, or dissection. Comparative angiography was available in 13 cases (although in some cases the studies were separated by a number...
