Relative contrast (mean ± standard deviation) for CBD, cRHD and cLHD in Nav-MRCP, BH-CS- and BH-PI-MRCP

	Nav	BH-CS	P (CS vs Nav)	BH-PI	P (PI vs Nav)
CBD	0.889 ± 0.039	0.845 ± 0.053	<0.001	0.834 ± 0.061	<0.001
cRHD	0.894 ± 0.045	0.849 ± 0.050	<0.001	0.838 ± 0.058	<0.001
cLHD	0.892 ± 0.034	0.844 ± 0.052	<0.001	0.833 ± 0.057	<0.001

CS, compressed sensing; PI, parallel imaging; SI, signal intensity; RC, relative duct-to-periductal contrast ratio; CBD, common bile duct; cRHD/cLHD, central right hepatic duct/left hepatic duct.
