Preoperative FRL-F Parameter in Relation to Actual Postoperative Remnant Liver Function (^ActualRL-F) Measured by Gmean Dataset

Preoperative parameter	Postoperative parameter	Pearson r	Difference	P
^Gmean FRL-F	^Actual RL-F^*	0.96	−0.62%/min/m²	0.009^†
^SPECTFRL-F	^Actual RL-F^*	0.94	−0.47%/min/m²	0.068
^CTFRL-Function	^Actual RL-F^*	0.96	−2.56%/min/m²	<0.0001^†

↵* Measured by Gmean.
↵† P < 0.05.
Although all parameters demonstrated strong correlation with ^ActualRL-F, only ^SPECTFRL-F demonstrated no significant difference in actual values between preoperatively estimated and actual remnant liver function.
