Large coverage peripheral artery 3D vessel wall MRI using SUper-Resolution for Psf-Restored Isotropic turbo Spin Echo (3D SURPRISE)

Vessel wall MRI for peripheral artery disease (PAD) atherosclerotic lesions requires large coverage due to diffuse distribution of lesions, and high-resolution due to smaller plaque components. However current large coverage PAD approaches uses gradient echo sequences that may not be optimal for highly calcified PAD lesions. Therefore we developed and evaluated a large coverage 3D femoral MRI using SUper-Resolution for Psf-Restored Isotropic turbo Spin Echo (3D-SURPRISE) that provides shorter scan times with higher SNR and CNR than an existing large coverage gradient echo femoral vessel wall MRI (3D-MERGE).
