CMR measurements correlate well with DSCT for TAVI annulus sizing; leaves open whether it can replace DSCT without affecting prosthesis selection or outcomes.
Prior to transcatheter aortic valve implantation (TAVI), dual-source computed tomography (DSCT) is currently the preferred imaging modality for correct prothesis selection by accurate analysis of aortic annulus and ascending aorta. However, DSCT is associated with the need for contrast administration and radiation exposure.
