TABLE 1.

Timing of the BGS pulses for PCASL and FT‐VSI ASL sequences used in this study ^a

Methods	PLD (s)	Timing (s) of BGS pulses
		Pulse 1	Pulse 2	Pulse 3
PCASL	2.00	0.31	1.53	N/A
VSASL (FT‐VSI)	0.60	0.27	0.28	0.30
	0.90	0.06	0.09	0.58
	1.20	0.52	0.91	1.08
	1.50	0.65	1.25	1.44
	1.80	0.74	1.47	1.72

^aThe timing is defined as the delay from the end of the labeling module to the center of the BGS pulses.
