Abstract
Background MMeasurement of myocardial T1 mapping is possible with most of the clinically used magnets using sequences based on modification (MOLLI) or shortening (shMOLLI) of the Look-Locker (LL) sequence. However, the robustness of T1 post-processing approaches has not been systematically examined for these sequences, nor for different field strengths, in native and post-contrast T1 maps. Moreover, repeatability of measurements in conditions with altered geometric relations of cardiac chambers and wall thickness commonly observed in clinical settings remains unknown.
Highlights
MMeasurement of myocardial T1 mapping is possible with most of the clinically used magnets using sequences based on modification (MOLLI) or shortening of the Look-Locker (LL) sequence
T1 times derived in septal myocardium showed excellent intra and inter-observer repeatability at both field strengths and in all diagnosis categories (CoV=1.5- 4.1)
We evaluated T1 maps obtained in 82 consecutive subjects referred for clinical cardiac magnetic resonance (CMR)
Summary
Standardization of myocardial T1 time measurements in clinical setting using MOLLI, shMOLLI and LL at 1.5T and 3T - the CONSEPT study. From 16th Annual SCMR Scientific Sessions San Francisco, CA, USA. From 16th Annual SCMR Scientific Sessions San Francisco, CA, USA. 31 January - 3 February 2013
