Table 2 Intermodality agreement between CTA and MRA in rating stenosis. The arterial stenosis degree: 0, normal; 1, minimal stenosis of less than 50 %; 2, one lesion with 50 % or greater stenosis; 3, more than one lesion with 50 % or greater stenosis; 4, occlusion

From: The diagnostic value of non-contrast enhanced quiescent interval single shot (QISS) magnetic resonance angiography at 3T for lower extremity peripheral arterial disease, in comparison to CT angiography
