Table 3. Comparison of left ventricular quantitative parameters between the CAD group and non-CAD group (stenosis ≥50% on CAG as the case standard).

Quantitative parameters	Participant level (n=49)					Vessel level (n=147)
	Non-CAD group (n=16)	CAD group (n=33)	t	P		Non-CAD group (n=73)	CAD group (n=74)	t	P
LV-rMBF (mL/min/g)	1.07±0.26	1.00±0.20	1.03	0.31		1.04±0.24	1.01±0.22	0.81	0.42
LV-sMBF (mL/min/g)	2.35±0.77	1.41±0.41	4.56	<0.05*		2.05±0.80	1.30±0.46	7.08	<0.05*
