MATERIALS AND METHODS We retrospectively reviewed MRAs of 2866 patients obtained by using a standard noncontrast MRA protocol and two 1.5T MR imaging units and reviewed the English language literature to...

Quantifying Intracranial Internal Carotid Artery Stenosis on MR Angiography.

BACKGROUND AND PURPOSE Intracranial atherosclerosis is a common cause of ischemic stroke. Intracranial stenosis is most commonly quantified by the Warfarin-Aspirin Symptomatic Intracranial Disease method, which involves calculating a ratio of luminal diameter measurements on conventional angiography. Our purpose was to determine whether a single linear measurement of the narrowest caliber of th...

MR 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...

Carotid Artery Stenosis: Comparison of 3D Time-of-Flight MR Angiography and Contrast-Enhanced MR Angiography at 3T

Purpose. The aim of this study was to assess the correlation of 3D time-of-flight MR angiography (TOF MRA) and contrast-enhanced MR angiography (CEMRA) for carotid artery stenosis evaluation at 3T. Material and Methods. Twenty-three patients (5 f, 18 m; mean age 61 y, age range 45-78 y) with internal carotid artery stenosis detected with ultrasonography were examined on a 3.0T MR system. The MR...
