Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue [PDF]

, 2010
Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Myocardial T2*effects 3D MRI myocardial strain in patients with transfusion-induced haemochromatosis

, 2007
Early detection of transfusion-induced myocardial iron loading and its intervention with aggressive chelation therapy may delay or reverse heart failure. Myocardial T2* relaxometry has been proposed as a sensitive measure of myocardial iron accumulation.

Myocardial Strain for the Differentiation of Myocardial Involvement in the Post-Acute Sequelae of COVID-19—A Multiparametric Cardiac MRI Study

Tomography
Myocardial involvement was shown to be associated with an unfavorable prognosis in patients with COVID-19, which could lead to fatal outcomes as in myocardial injury-induced arrhythmias and sudden cardiac death.

Increased myocardial extracellular volume assessed by cardiovascular magnetic resonance T1 mapping and its determinants in type 2 diabetes mellitus patients with normal myocardial systolic strain

Cardiovascular Diabetology, 2018
Background Cardiac magnetic resonance (CMR) T1 mapping and tissue-tracking strain analysis are useful quantitative techniques that can characterize myocardial tissue and mechanical alterations, respectively, in patients with early diabetic cardiomyopathy.

Spatially resolved imaging of myocardial function with strain-encoded MR : comparison with delayed contrast-enhanced MR imaging after myocardial infarction.

, 2004
Strain-encoded magnetic resonance (MR) imaging was prospectively evaluated for direct imaging of systolic myocardial strain and compared with cross-registered delayed contrast material-enhanced MR imaging in five healthy volunteers and nine patients with
