“…However, these segments were situated at the edge of the MRA FOV, which may have decreased the possibility to evaluate the region proximal or distal to the stenosis. Overestimation of stenosis by MRA could in the calf be due to the limited spatial resolution and signal‐to‐noise ratio of body coil imaging in agreement with other reports (26) (Fig. 4).…”

Purpose: To determine whether contrast‐enhanced 3D MR angiography (CE MRA) could replace digital subtraction angiography (DSA) for the evaluation of atherosclerotic peripheral vascular disease of the lower leg and foot. Material and Methods: Thirty‐five patients with symptoms of atherosclerotic disease of the leg were examined prospectively with CE MRA of the foot and the lower legs as well as with DSA from the aorta to the pedal arches. The MRA technique was focused on optimal imaging of the arteries of the foot. Results: The agreement between CE MRA and DSA for grading of stenosis was moderate to good (weighted κ‐values 0.48–0.80). The sensitivity of CE MRA for detection of significant stenosis (≥50%) was 92% and the specificity was 64% with DSA as gold standard. Conclusion: CE MRA is a fairly accurate method for the demonstration of atherosclerotic disease below the knee including the pedal arches. It can replace DSA for the assessment of distal arteries in patients with impaired renal function. However, image quality and resolution still needs to be improved before CE MRA can become the method of choice in all patients.

“…In our opinion, a possible explanation is the natural course of the iliac vessels crossing the partition in the z-axis; additional kinking in elderly patients aggravates this problem. 32 In conclusion, our prospective comparison shows that MRA is a noninvasive imaging modality that has a diagnostic accuracy comparable to DSA for the detection of significant stenotic lesions in patients with PAOD. Several technical reasons explain potential disagreements concerning the exact grading of stenoses; however, basing the therapeutic strategy solely on the results of MRA has the potential to withhold DSA without any therapeutic consequence in the majority of cases.…”

“…48 Most MRAs are performed using contrast, most commonly gadolinium. 53 Similar benefits and limitations exist in the imaging of bypass grafts. Contrast-enhanced TOF MRA is useful as a noninvasive imaging test to define lower-extremity vascular anatomy.…”
