“…The measurement of LV and right ventricular strain by using cine cardiac MR has been reported in a few previous studies (28,29). It has been suggested that the measurement of LV strain by using tissue tracking with cine cardiac MR imaging was as useful as tagged MR imaging and speckle tracking echocardiography (28,30,31). The interobserver reproducibility for tissue tracking was similar to echocardiography in the measurement of longitudinal LV global strain (28).…”

).q RSNA, 2014 Purpose:To investigate the association between left atrial (LA) function and left ventricular myocardial fibrosis using cardiac magnetic resonance (MR) imaging in a multi-ethnic population. Materials and Methods:For this HIPAA-compliant study, the institutional review board at each participating center approved the study protocol, and all participants provided informed consent. Of 2839 participants who had undergone cardiac MR in 2010-2012, 143 participants with myocardial scar determined with late gadolinium enhancement and 286 age-, sex-, and ethnicity-matched control participants were identified. LA volume, strain, and strain rate were analyzed by using multimodality tissue tracking from cine MR imaging. T1 mapping was applied to assess diffuse myocardial fibrosis. The association between LA parameters and myocardial fibrosis was evaluated with the Student t test and multivariable regression analysis. Results:The scar group had significantly higher minimum LA volume than the control group (mean, 22.0 6 10.5 [standard deviation] vs 19.0 6 7.8, P = .002) and lower LA ejection fraction (45.9 6 10.7 vs 51.3 6 8.7, P , .001), maximal LA strain (S max ) (25.4 6 10.7 vs 30.6 6 10.6, P , .001) and maximum LA strain rate (SR max ) (1.08 6 0.45 vs 1.29 6 0.51, P , .001), and lower absolute LA strain rate at early diastolic peak (SR E ) (20.77 6 0.42 vs 21.01 6 0.48, P , .001) and LA strain rate at atrial contraction peak (SR A ) (21.50 6 0.62 vs 21.78 6 0.69, P , .001) than the control group. T1 time 12 minutes after contrast material injection was significantly associated with S max (b coefficient = 0.043, P = .013), SR max (b coefficient = 0.0025, P = .001), SR E (b coefficient = 20.0016, P = .027), and SR A (b coefficient 20.0028, P = .01) in the regression model. T1 time 25 minutes after contrast material injection was significantly associated with SR max (b coefficient = 0.0019, P = .016) and SR A (b coefficient = 20.0022, P = .034). Conclusion:Reduced LA regional and global function are related to both replacement and diffuse myocardial fibrosis processes.Clinical trial registration no. NCT00005487q RSNA, 2014

“…Cine shortaxis midventricular images were used for global circumferential strain ( εcc) measurement as described previously. 22 The assessment was performed using the TomTec Diogenes ® software (TomTec Imaging Systems, Munich, Germany), which is a vector-based analysis tool, intended for the quantification of myocardial deformation and movement using dynamic 2-dimensional cMRI data. Diogenes ® magnetic resonance feature tracking takes advantage of an approach whereby features are not "detected", rather they are "tracked"; that is, followed in time, starting from a reliable existing instantaneous trace that is manually drawn by the operator over a single frame.…”

“…The complexity and time taken for acquisition and analysis of tagging has made the transition of this technique from a research tool into everyday use very challenging. We however note that with the recent availability of feature-tracking CMR, some of the limitations of myocardial tagging are easily overcome and the former may become an integral part of CMR examination to detect abnormal strain and strain rate patterns in amyloid patients [3].…”

Comparison of Magnetic Resonance Feature Tracking for Strain Calculation With Harmonic Phase Imaging Analysis

Abstract: FT-based assessment of epsilon(cc) correlates highly with epsilon(cc) derived from tagged images in a large DMD patient population with a wide range of cardiac dysfunction and can be performed without additional imaging.
