We evaluated the peripheral MR angiography (MRA) of 8 healthy volunteers using conventional and enhanced acceleration-selective arterial spin labeling (cAccASL, eAccASL), and Background suppressed single shot TFE-TRANCE (BASS TRANCE). In eAccASL, additional 180°refocusing pulses and motion sensitized gradients (MSGs) will compensate for B₁ inhomogeneity and eddy current effects at 3.0 Tesla. Contrast ratios for BASS TRANCE was the highest values, compared to cAccASL and eAccASL. However, qualitative assessment showed eAccASL could provide more robust visualization than cAccASL and similar visualization to BASS TRANCE. Therefore, eAccASL can provide the more robust peripheral MRA without any gating.
