Comprehensive Magnetic Resonance of Peripheral Arterial Disease - Full Text View

Purpose

The purpose of this study is to develop new ways of imaging fatty blockages in the leg arteries to improve upon techniques used now and to develop new ways of understanding how new treatments may affect the disease.

Primary Outcome Measures:

We hypothesize that multi-modality magnetic resonance can test the efficacy of lipid lowering therapy therapy on the vessel wall, atherosclerotic plaque, and skeletal muscle perfusion and energetics in PAD [ Time Frame: 2 years ] [ Designated as safety issue: No ]
