Efficacy Evaluation of Dotarem Compared to Gadovist in the Diagnosis of Peripheral Arterial Disease - Full Text View

Purpose

This study is an efficacy evaluation of Dotarem®-enhanced magnetic resonance angiography (MRA) compared to Gadovist®-enhanced MRA in the diagnosis of clinically significant abdominal or lower limb arterial diseases.

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.
