From: Myocardial involvement characteristics by cardiac MR imaging in neurological and non-neurological Wilson disease patients

Parameters	Intra-observer		Inter-observer
Parameters	ICC	95% CI	ICC	95% CI
Native T1 (ms)	0.99	0.98–0.99	0.97	0.93–0.99
T2 (ms)	0.96	0.92–0.98	0.92	0.89–0.96
GRS (%)	0.95	0.92–0.98	0.89	0.86–0.94
GCS (%)	0.94	0.92–0.97	0.90	0.86–0.95
GLS (%)	0.97	0.96–0.98	0.92	0.89–0.97

GRS Global radial strain, GLS Global longitudinal strain, GCS Global circumferential strain
