“…However, the incidence of angiographically occult patent vessels varies between centers. 57 Moreover, in a multicenter trial, arteriography and MRA were equally accurate compared with intraoperative angiography or post-PTA arteriography, 57 while in other studies arteriography was even more accurate than MRA. 60,61 Not until randomized trials are performed that compare outcomes of distal bypass surgery based on arteriography and MRA will it be clear which modality is to be preferred.…”

“…Several studies compared treatment plans made by different observers based on arteriography and MRA. 10,20,25,36,41,[57][58][59][60][61][62][63][64] When MR angiograms were technically adequate, the concordance in proposed interventions exceeded 85%. Studies designed as such remain hypothetical because clinical decision making is subject to interindividual variability.…”

“…Magnetic resonance (MR) angiography is emerging as a reasonable adjunct or alternative to the conventional approach of catheter angiography (11). The lower degree of invasiveness and smaller likelihood of complications with MR angiography are well received by patients and thus contribute to arguments promoting the cost-effectiveness of this examination (12).…”

Objective: The aim of this study was to compare the diagnostic accuracy of contrastenhanced (CE) three-dimensional (3D) moving-table magnetic resonance (MR) angiography with that of selective digital subtraction angiography (DSA) for routine clinical investigation in patients with peripheral arterial occlusive disease. Methods: Between April 2012 and May 2013, the lower extremities of 30 patients with suspected peripheral vascular disease performed both conventional digital subtraction angiography and three-dimensional contrast-enhanced MR angiography MRA with the automatic table movement technique (MoBI-trak). DSA and MR angiographic images were interpreted prospectively, one vascular radiologist interpreted the digital subtraction angiographic images and the second vascular radiologist interpreted the MR angiographic images; both interpreters were unaware of the clinical history and the results of the other examination. Results: The MRA and DSA studies in the 30 study patients produced 870 arterial segments for interpretation. The sensitivity of MRA for the detection of mild stenotic, hemodynamically severe stenotic and occlusions were 86.1%, 90.5% and 93.9%, respectively. Corresponding specificity was 90.1%, 96.1% and 97.5%, respectively. Conclusion: Our prospective comparison shows that three-dimensional contrast-enhanced automatic moving-table MRA is a noninvasive imaging modality that has a diagnostic accuracy comparable to DSA for the assessment of peripheral arterial occlusive disease.

“…The reference standard, however, is not flawless in helping distinguish individuals with disease from those without. For example, intraarterial x-ray angiography (an invasive procedure involving arterial catheterization) is generally considered to be the reference standard for vascular disease but has been shown to result in missed patent runoff vessels (16,17). Because computed tomographic (CT) angiography and MR angiography (18 -20) provide three-dimensional information, they may surpass intraarterial angiography.…”
