Simultaneous Visualization of the Carotid and Subclavian Arteries Using Non-Contrast-Enhanced MR Angiography With a 3D Fast Field Echo Sequence and Time-Spatial Labeling Inversion Pulse: A Comparison With 3D Time-of-Flight MR Angiography.

ABSTRACT:

Background

Carotid artery stenosis is a major cause of stroke. Non-contrast MR angiography (MRA) using time-spatial labeling inversion pulse (Time-SLIP) may offer potential advantages over 3D time-of-flight (TOF)-MRA for simultaneous visualization of carotid, vertebral, and subclavian arteries, but remains uninvestigated.

Purpose

To determine optimal black blood inversion time (TI) for visualizing the carotid and subclavian arteries using three-dimensional (3D) fast field echo (FFE) Time-SLIP MRA, and to compare its image quality with 3D TOF-MRA.

Study type

Prospective.

Subjects

11 healthy adults (23-57 years, five females) and 4 patients (76-93 years, three females) with cervical vascular abnormalities. All patients had ICA stenosis. One patient exhibited ECA
