Despite the benefits of SWI vessel wall imaging, namely blood flow independence, three dimensional coverage, and sensitivity to calcification, the accuracy of SWI in morphological measurement has yet to be addressed. Here we compared SWI with the reference method, single slice DIR turbo spin echo (TSE), on measuring femoral artery lumen and wall size.
