Further study details as provided by Guerbet:

Primary Outcome Measures:
  • Intra-patient Accuracy (Percent Agreement), On-site Data [ Time Frame: up to one month ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    • 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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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.
  • Patient scheduled for a conventional X-Ray angiography (intra-arterial Digital Substraction Angiography = DSA) within 30 days of MRA with a minimum time interval of at least 24 hours between the 2 examinations.

Exclusion Criteria:

  • 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.
