Myocardial deformation imaging with strain imaging using speckle tracking Echocardiography (STE) and Cardiovascular Magnetic Resonance tagging now has been applied for assessment of myocardial deformation. Recently, feature tracking on standard steady state free precession imaging (SSFPFT) has been developed for the assessment myocardial deformation. The purpose of this study was to compare circumferential and radial strain by feature tracking on SSFP cine CMR images as compared to SPAMM tagging technique and speckle tracking echocardiography. The result support that the radial and circumferential strain with SSFP-FT has a good agreement with tagging and Echocardiography methodologies.
