Feasibility of Image Fusion for Concurrent MRI Evaluation of Vessel Lumen and Vascular Calcifications in Peripheral Arterial Disease

摘要

OBJECTIVE. With MR angiography of peripheral arterial disease, calcifications are unapparent, so a separate calcification-sensitive pulse sequence (proton density-weighted inphase 3D stack-of-stars [PDIP-SOS]) is needed for complete assessment. We hypothesized that, despite being acquired separately, MR angiography and PDIP-SOS images could be coregistered and fused without loss of significant diagnostic information.
