Current MRI methods used to measure left ventricular strain, including tissue tracking or phase-based methods, require onerous post-processing or specialty pulse sequences. We propose an alternative method for the determination of peak systolic global circumferential, longitudinal and radial strains that does not rely on tissue tracking and is based on basic SSFP cines and left ventricular volume analysis. The purpose of this study is to compare this new method to conventional tissue tagging-derived strains.
