Late gadolinium enhancement quantitative results at best time-delays for different gadobutrol doses and its relative comparison

Gadobutrol Dose	0.1 mmol/kg	0.2 mmol/kg		0.2 mmol/kg (at 20 min) vs. 0.1 mmol/kg (at 10 min)
Time delay	10 min	20 min	COMPARISON	p-value	ICC*	mean difference (LOA)
LGE mass (all patients)	11% (16.4)	12% (14.5)		0.059	0.957	0.9% (7, −5.2)
LGE mass (CAD patients only)	19% (17)	19.8% (20.2)		0.248	0.967	0.2% (6.3, −5.8)
LGE mass (HCM patients only)	7% (6.7)	10.3% (8.4)		0.244	0.876	1.6% (7.6, −4.4)
