Cardiac magnetic resonance feature-tracking (CMR-FT) has emerged as a reference standard for the evaluation of cardiac morphology and function. But, the performance of CMR-FT may be affected by data undersampling as done in several real-time cardiac MRI techniques. In our study, we evaluated the performance of CMR-FT for myocardial strain quantification from real-time cardiac cine MRI when compared to standard cardiac cine in cardiac disease patients. We found that even though there is good agreement between the values derived from the real-time and standard cine MRI, care should be taken as measures from the real-time cine can be underestimated.
