Abstract:
Objective To evaluate the accuracy of multi-detector spiral CT (MSCT) semiautomated volumetric measurement of right lobes and its value in living donor liver transplantation (LDLT). Methods Fifty-six donors underwent four phases MSCT. Pre-operative liver volumes of two measurements [IQQA(R)-liver semi-automated (Vs) and manual volume (Vm) measurements] in portal vein phase were compared with intra-operative measurement (Vio) by means of water displacement. Results Correlation analysis and Bland-Altman tests were used for statistical analysis.Results Pre-operative measurements of grafts resulted in a mean Vs, Vm, Vio of (818. 60 ± 161.43)cm3 , (880. 16 ± 169. 92) cm3 and (669. 84 ± 141.37) cm3 respectively. All corresponding pre-and intra-operative data were correlated significantly with each other. There was a good correlation between Vs and Vio(r= 0. 778, P＜0. 05), so did Vm and Vio(r= 0. 746, P＜0. 05). The equations of linear regression were Vio = Vs × 0. 681 + 112. 26, and Vio = Vm × 0. 620 + 123. 81 respectively. Exact 95 % CIs and the extent of concordance were 121.57-175. 95 cm3, -354. 135-56. 62 cm3 for semiautomated measurements, and 180. 09-240. 56 cm3 , - 438. 66-18. 01 cm3 for manual measurements,respectively. Conclusion Semi-automated method for the volumetric measurements of the right liver lobes in LDLT is more accurate than the manual method.
