Most common methods to assess future liver remnant size

Formula	Method to calculate	Strengths	Limitations
FLR/TLV	(FLR ml/TLV ml)×100	Accurate	Complicated, time-consuming
sFLR	(FLR ml/TELV ml (794–1267×BSA)) ×100	Easy to perform, widely used currently	Potentially inaccurate for large tumours
FLR/BW-ratio	FLR in ml/BW in kg	Easy to perform	Rarely used

FLR; future liver remnant; TLV, total liver volume; sFLR, standardized FLR; TELV, total estimated liver volume; BSA, body surface area; BW, bodyweight.
