Exclusion criteria
Exclusion criteria: Patient with a contraindication to MRI (e.g., pacemaker, aneurysm clip, severe claustrophobia, metallic joint replacement or others according to the imaging laboratory's standard practice). Patient with known severe adverse drug reaction or contraindication to one of the investigational products (Dotarem® or Gadovist®). Patient having received any contrast media within 48 hours prior to administration of investigational product for the enhanced-MRA. Patient planned to undergo therapeutic intervention in abdominal or lower limb vessels between the time of MRA and X-ray Angiography will be performed. Patient who had a major cardiovascular event within 30 days prior to the inclusion. Patient treated with unilateral hip replacement, abdominal aortic or iliac graft or stent. Patient having participated in any investigational drug study within 30 days prior the study enrolment. Any condition which, based on the investigator's clinical judgement, would prevent the patient from completing all trial assessments and visits. Patient under guardianship and/or Inability or unwillingness to cooperate with the requirements of this trial. Pregnant or breast-feeding patient. Patients already included in this trial

| Measure | Time frame |
|---|---|
| Main Objective: To demonstrate the clinical equivalence (statistical non-inferiority) in terms of global diagnostic performance of DOTAREM®-enhanced MRA as compared to GADOVIST® - enhanced MRA by comparing the degree of agreement at the patient level of each MRA method when using X-Ray Angiography (DSA) as a gold standard.;Secondary Objective: To compare diagnostic criteria (Se, Sp, PPV, NPV) of DOTAREM®-enhanced MRA and GADOVIST®-enhanced MRA using X-Ray Angiography as a gold standard. To compare DOTAREM®-enhanced MRA versus GADOVIST®-enhanced MRA in terms of : o artery visualization, o number of significant stenosis depicted, o number of technical failures (not assessable segment), o duration of examination, o collateral circulation visualization, o pedal vessel and smaller branches visualization, o diagnostic confidence o patient clinical management o venous overlap To compare the clinical tolerance (AE) of both contrast media from inclusion and up to the last visit performed. ;Primary end point(s): The primary criterion is the 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. This criterion will be evaluated at the patient level from the result of site reading. On site readers will be differents and blind from results of the other imaging procedures (MRA and DSA). | — |
