Purpose of the Study:

To review recent advancements in peripheral MRA.
To guide effective utilization of these new techniques.
To highlight common pitfalls and their avoidance in peripheral MRA.

Main Methods:

Time-resolved MR angiography.
Stepping table bolus chase 3D MR angiography.
Fluoro-triggering and parallel imaging.
Sub-systolic thigh compression for venous suppression.
