Comparison of 3D contrast enhanced magnetic resonance angiography and conventional arteriography in iliofemoral arteries

Twenty-three patients underwent conventional arteriography and 3D contrast enhanced magnetic resonance angiography explorations. The study was limited to the iliofemoral arteries (13 segments for each patient). Each segment w as classified as having 0-49 %, 50-99 % or 100 % stenosis. Overall results were excellent with K = 0.822, sensitivity 92 % and specificity 93 %. Segme nt by segment analysis corroborated the overall results except for the inte rnal iliac arteries and the deep femoral arteries, demonstrating the limita tions of this technique in this serie.
