SENC MRI is an important technique for myocardium strain quantification. We proposed a modified SENC EPI sequence to only acquire about half of the total cardiac phases in order to get higher SNR strain images. The minimum strains can still be calculated with better SNR from LT/HT images. With the imaging time kept the same at one heartbeat, the SNR of the images is higher and strain calculation is more accurate. The timing of the end-systole stage can be determined by running a CINE scan prior to the SENC protocol.
