MRA of the forearms and hands is particularly challenging. There is a renewed interest in non contrast-enhanced (NCE) MRA techniques given the concerns of nephrogenic systemic fibrosis in patients with chronic kidney disease. Recently, QISS MRA technique has been implemented for imaging of the lower extremities and demonstrated to be rapid, easy to use, and insensitive to patient motion, heart rate and flow patterns. The purpose of this study was to investigate the feasibility of high resolution NCE-MRA of the hand and forearm arteries using the QISS technique.
