Quiescent-interval single-shot (QISS) has proven to be an accurate and robust alternative to contrast-enhanced MRA and CT angiography for the evaluation of peripheral arterial disease, but scan time is longer than with these other imaging tests. In this work, we demonstrate a pulse sequence modification that cuts QISS scan time in half while maintaining image quality.
