Key result
CSPAMM tagged CMR demonstrated good interstudy reproducibility for circumferential strain (CoV 3.7-5.5%) and LV twist (CoV 9.8-12.2%), but poorer reproducibility for radial strain (CoV 13.8-23.4%).

What is the reproducibility of myocardial strain and LV twist measured using CSPAMM tagged CMR in healthy volunteers?
CSPAMM tagged CMR provides reproducible measurements of circumferential strain and LV twist, but not radial strain, in healthy volunteers.
Swoboda et al. (2013) conducted an observational in Healthy volunteers (n=12). Complementary spatial modulation of magnetization (CSPAMM) tagged CMR was evaluated on Reproducibility of myocardial strain and left ventricular twist. CSPAMM tagged CMR demonstrated good interstudy reproducibility for circumferential strain (CoV 3.7-5.5%) and LV twist (CoV 9.8-12.2%), but poorer reproducibility for radial strain (CoV 13.8-23.4%).
