Myocardial T1 mapping: modalities and clinical applications

Christine L Jellis et al. Cardiovasc Diagn Ther. 2014 Apr.

Abstract

Myocardial fibrosis appears to be linked to myocardial dysfunction in a multitude of non-ischemic cardiomyopathies. Accurate non-invasive quantitation of this extra-cellular matrix has the potential for widespread clinical benefit in both diagnosis and guiding therapeutic intervention. T1 mapping is a cardiac magnetic resonance (CMR) imaging technique, which shows early clinical promise particularly in the setting of diffuse fibrosis. This review will outline the evolution of T1 mapping and the various techniques available with their inherent advantages and limitations. Histological validation of this technique remains somewhat limited, however clinical application in a range of pathologies suggests strong potential for future development.

Keywords: T1 mapping; extracellular volume; modified Look Locker inversion recovery (MOLLI); myocardial fibrosis.

MOLLI technique: pre-contrast (A) and post-contrast (B) T1 maps of the mid left ventricle left ventricle in short-axis view with the epicardium (white circle), endocardium (large red circle) and blood-pool (small red circle) outlined. An exponential recovery curve of signal intensities at different inversion times (TI) determines the myocardial (green line) and blood-pool (red line) T1 values which can then be used (with hematocrit) to determine the extracellular volume.
