In this work, slice following capabilities were added to a pre-existing CSPAMM bSSFP tagging sequence and tested on a 3T clinical scanner. Validation in static and moving phantoms plus SNR and tag-CNR comparisons was performed. Subsequently, and because of systolic base-to-apex long axis shortening in vivo, we tested the hypothesis that there exist significant differences in quantitative short axis strain and rotation measurements between slice-followed and non-slice-followed CSPAMM acquisitions.
