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.
