Abstract:

Objective To explore the value of residual liver volume in evaluation of liver reserve function on liver mass CT virtual imaging. Methods A retrospective analysis on 63 patients with liver mass was performed. Preoperative CT virtual imaging of liver mass，indocyanine green excretion test，and Child⁃Pugh score were conducted. As ICGR15 less than 10% was considered to be normal，the patients were divided into < 10% group（group A） and ≥ 10% group（group B）. The general condition，laboratory indexes，LV，TV，VSV and RLV were statistically analyzed in both groups，and the correlation between RLV and other indexes was analyzed. ROC curve was used to evaluate the efficacy of RLV for predicting liver dysfunction. Results Ascompared with those in group A，the patients in group B had greater age and higher TBIL level，higher Child⁃Pugh score，lower ALB level and smaller RLV（P < 0.05）. Spearman correlation analysis showed that RLV was negatively correlated with ICGR15，and the difference was statistically significant（P < 0.05）. The ROC curve showed that the AUC of RLV value for predicting liver dys⁃ function was 0.659（P < 0.05），and the sensitivity was 0.767. Conclusions Residual liver volume can be calculat⁃ ed by CT virtual imaging of liver space occupying lesion，which can further assess liver reserve function.
