Preliminary study of the accuracy of hepatic volume measurement by 3D + medical imaging visualization processing system / 肿瘤研究与临床

ABSTRACT

Objective To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the 3D + medical imaging visualization processing system. Methods Thirty patients who were clinically diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016. Preoperative thin-slice CT images were transferred into the 3D + medical imaging visualization processing system for hepatic volume measurement, the predictive resection volume were measured and statistically analyzed with that of intraoperative specimen according to water measurement method. Results All patients had complete resection of tumor, the average volume of predictive resection calculated by the 3D software was (408.84 ± 177.07) ml, the average volume of intraoperative specimen measured by the water test was (399.95 ± 176.15) ml, the difference was not statistically significant (t=1.502, P=0.144), and the average percentage error was (6.21 ± 4.73) %. Pearson correlation analysis showed that there was significant correlation between them (r=0.983, P<0.05). Conclusion 3D+medical image visualization processing system is a simple, intuitive and accurate method for liver volume measurement, which can provide the basis for the accurate measurement of liver volume and the implementation of complex hepatectomy, and guide the precise hepatectomy.
