Cardiac strain quantification is important in the assessment of regional myocardial function, and has many different clinical applications. The current gold standard for non-invasive myocardial strain measurement is cardiac magnetic resonance (CMR) tagging. It is also possible to estimate global and regional strain from standard (non-tagged) steady-state free precession (SSFP) cines using non-rigid registration , thereby removing the need to acquire additional sequences. We report an in-line implementation providing numerical and graphical strain measurements without user interaction as part of the standard SSFP acquisition.
