Scoring criteria for image diagnostic quality, where we abbreviate hepatic veins as HV, and portal veins as PV.

Score	overall quality	portal veins	hepatic veins
nondiagnostic (1)	no structures assessed	PV blurred	RHV blurred
limited (2)	limited assessment of several structures	lst-order branches of PV blurred	lst-order branches of RHV blurred
diagnostic (3)	all but 1–2 structures assessed	sharp first order branches of PV	sharp first order branches of RHV
good (4)	all structures assessed	sharp 2nd-order branches of PV	sharp 2nd-order branches of RHV
excellent (5)	sharp delineation of all structures	braches seen to within lcm of periphery	braches seen to within lcm of periphery
