In this study, we used blipped-CAIPIRINHA simultaneous multi-slice (SMS) technique to 1) extend bSSFP coverage to 3 simultaneous slices and 2) apply it to cardiac T1 mapping. Tests were conducted on phantom and in six healthy volunteers. SMS blipped-CAIPIRINHA-bSSFP sensitivity to slice gap, slice thickness and pixel bandwidth was successfully established in terms of SNR. Native T1 quantification values over three levels of the heart (base, mid and apex) were reliable, accurate, and in line with the ones obtained with a regular single slice acquisition.
