Assessing regional left ventricular thickening dysfunction and dyssynchrony via personalized modeling and 3D wall thickness measurements for acute myocardial infarction

“…To date, tagging MRI is still considered the gold standard for wall deformation analysis, as it is known to accurately assess intramyocardial motion and distinguish the extent of myocardium deformation between normal and infarcted myocardium with the use of tag lines. However, it has been noted that motion analysis has often been restricted within systole using tagging MRI due to tag fading . Although this can be countered with the utilization of more advanced imaging sequences, such as the CSPAMM sequence at the cost of doubling the acquisition time, other concerns such as the lack of fully automated tagged MRI‐based strain measurement acquisition and the resulting need for skilled user input necessary to correct errors due to semiautomated processes such as tag line tracking have limited this method from entering mainstream diagnostics .…”
