Whole-body magnetic resonance angiography at 3.0 Tesla.

Abstract

The quality of magnetic resonance (MR) angiography could be substantially improved over the past several years based on the introduction and application of parallel imaging, new sequence techniques, such as, e.g., centric k-space trajectories, dedicated contrast agents, and clinical high-field scanners. All of these techniques have played an important role to improve image resolution or decrease acquisition time for the dedicated examination of a single vascular territory. However, whole-body MR angiography may be the application with the potential to profit most from these technical advances. The present review article describes the technical innovations with a focus on parallel imaging at high field strength and the impact on whole-body MR angiography. The clinical value of advanced whole-body MR angiography techniques is illustrated by characteristic cases.
