Left Example images for multi-contrast plaque characterization for a normal femoral artery (top row) and different types of wall abnormalities. Time-resolved (CINE) 2D phase-contrast MRI with 3-directional velocity encoding at the same anatomic location was used to derive wall shear stress along the femoral artery lumen circumference. Right: The polar plots show the segmental distribution of peak systolic wall shear stress for patients with femoral wall abnormalities (wall thickening or plaque, red squares) compared to patients with normal femoral walls (patients with no femoral wall abnormalities, black circles). * = significant difference, P< 0.05.
