Primary Outcome Measures:
- Intra-patient Accuracy (Percent Agreement), On-site Data [ Time Frame: up to one month ]intra-patient accuracy (percent agreement) of each type of MRA examination (Dotarem® or Gadovist®-enhanced MRA) in assessing the lesions of the concerned territory as compared with the gold standard, X-ray angiography.
Secondary Outcome Measures:
- Intra-patient Accuracy, in Off-site Readings [ Time Frame: up to one month ]• Intra-patient accuracy (percent agreement) of each type of MRA examination (Dotarem® or Gadovist®-enhanced MRA) in assessing the lesions of the concerned territory as compared with the gold standard, X-ray angiography, in off-site readings, using the same methodology as that used for the primary criterion
- Specificity [ Time Frame: up to one month ]Specificity of Dotarem® and Gadovist®-enhanced MRA examinations at the segment and the patient levels (gold standard = x-ray angiography) in on-site readings; no stenosis and non significant stenosis were grouped as one class (non significant stenosis = negative segment).
- Sensitivity [ Time Frame: up to one month ]sensitivity of Dotarem® and Gadovist®-enhanced MRA examinations at the segment and the patient levels (gold standard = x-ray angiography) in on-site; moderate, severe stenosis and occlusion were grouped as one class (significant stenosis = positive segment).

Criteria
Inclusion Criteria:
- Male or female, aged ≥ 18 years.
- Patient with infrarenal aorta or chronic lower limb ischemia with various clinical signs of gravity (stages II-IV according to the classification of Leriche and Fontaine) or/and Doppler ultrasonography indicating abdominal or lower limb arteriopathy.
