Last updated: August 18, 2009
Last verified: August 2009
To investigate the diagnostic performance of whole body magnetic resonance angiography (WB-MRA) using subsystolic venous compression of the thigh.

Condition Intervention
Atherosclerosis Intermittent Claudication Procedure: Whole body magnetic resonance angiography

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Whole Body Magnetic Resonance Angiography in Patients With Symptomatic Peripheral Ischemia. Experience With Venous Compression.

Further study details as provided by Copenhagen University Hospital at Herlev:

Primary Outcome Measures:
  • Vascular diagnostic quality on the WB-MRA. Degree of arterial stenosis on the WB-MRA [ Time Frame: 1 month ]

Estimated Enrollment: 36
Study Start Date: June 2008
Study Completion Date: March 2009
Intervention Details:
    Procedure: Whole body magnetic resonance angiography
    Magnetic resonance angiography using a paramagnetic contrast agent.Venous compression performed with a blood-pressure cuff around both thighs.
Detailed Description:
WB-MRA is an examination that can evaluate the arteries from head to feet. Timing of the injected bolus of contrast medium can be difficult, especially in the legs. As the result of the WB-MRA depends on the contrast medium only being in the arteries at the time of examination, the use of venous compression is a possible way of overcoming the problem of early venous filling, that can hamper the diagnostic value of the examination. Venous compression is performed with a blod pressure cuff around the thighs. It is inflated to subsystolic pressure (45 mm Hg). This elevated pressure leads to filling of the lower leg arteries and late venous filling.
