High-resolution 3D non-contrast-enhanced, ECG-gated, multi-step MR angiography of the lower extremities: Comparison with contrast-enhanced MR angiography

Abstract: We demonstrated that 3D non-ceMRA represents a very promising technique in patients with lower extremities PVD and could be used as an alternative if gadolinium-based contrast agents cannot be administered.

“…In this initial study, the authors report a sensitivity of 85% and specificity of 76% for grading of stenoses in comparison to CE-MRA. A recent study by Mohrs et Tables 4 and 5 extremities without covering the feet [13]. Their data corroborate our results with similar sensitivity and specificity values of 94% and 86% for the pelvic and femoral arteries, and 93% and 87% for the popliteal and calf arteries, respectively.…”

“…Moreover, their inclusion criteria were less strict than ours as they enrolled patients with "a clinically suspected PVD" instead of proven and clinically relevant stenoses planned for enrolment in PTA, as in our population. Higher numbers of stenoses bear a higher risk of image deterioration, but the exact figures for PVD and its severity were not specified in this previous study [13], while in our study collective all patients presented with symptomatic PVD. Only a few clinical studies exist comparing CE-MRA with DSA as a reference standard.…”

“…The arterial vascular tree was divided into 32 segments for analysis of image quality and diagnostic performance: abdominal aorta (1), pelvic vessel segments including right and left common iliac artery (2, 3), right and left external iliac artery (4,5), and right and left common femoral artery (6,7), thigh vessel segments including right and left deep femoral artery (8,9), right and left proximal and distal superficial femoral artery (10-13), right and left proximal, middle, and distal popliteal artery (14)(15)(16)(17)(18)(19), and calf vessel segments including right and left proximal and distal anterior tibial artery (20)(21)(22)(23), right and left tibiofibular trunk (24,25), right and left proximal and distal posterior tibial artery (26)(27)(28)(29), and right and left proximal and distal fibular artery (30-33). Two blinded readers (M.W.…”
