Feature-tracking cardiovascular magnetic resonance as a novel technique for the assessment of mechanical dyssynchrony

Comparison of strain measurement from multimodality tissue tracking with strain-encoding MRI and harmonic phase MRI in pulmonary hypertension

“…Prior studies comparing other feature tracking software and tagging analysis of CMR images have been limited largely to only LV strain [26][27][28]. There are no reports comparing feature tracking to SENC or other methods of RV strain analysis.…”

Prognostic value of myocardial deformation imaging by cardiac magnetic resonance feature-tracking in patients with a first ST-segment elevation myocardial infarction

“…useful for the prediction of all-cause death, hospitalization for heart failure and adverse arrhythmic cardiac events. [1][2][3] Due to its high spatial resolution and signal-to-noise ratio images, CMR imaging permits highly reliable tracking of myocardial deformation and evaluation of LV strain, as well; [4,8,14] consequently, CMR assessment of LV strain (which has been demonstrated to be more closely related to myocyte metabolism and contractility than LVEF) may result useful in the risk stratification of STEMI patients. [4] Historically, LV strain in CMR has been evaluated using the tagging technique; however, myocardial tagging (in which virtual markers in the myocardium are obtained with magnetization saturation bands) requires complex and time-consuming data acquisition and postprocessing.…”

Prediction of functional recovery by cardiac magnetic resonance feature tracking imaging in first time ST-elevation myocardial infarction. Comparison to infarct size and transmurality by late gadolinium enhancement

“…In the present study, we used the (feature tracking imaging) FTI algorithm, which can be applied to cine sequences from different vendors and field strengths and obviate the need for dedicated pulse sequences [12][13][14][15][16]. Using FTI we sought to investigate whether quantification of circumferential and longitudinal strains can be used to estimate infarct size by late gadolinium enhancement (LGE) and clinical outcomes in patients with first time STEMI.…”
