摘　　要：目的 探讨应用3D＋医学影像可视化处理系统测量原发性肝细胞癌行精准肝切除时肝脏体积的准确性.方法 选取2016年1月至11月临床拟诊断为原发性肝细胞癌并术前评估后可行手术切除的患者30例,术前均行薄层CT扫描,然后应用3D＋医学影像可视化处理系统测量肝体积,与术中切除的实际体积比较并进行相关性分析.结果 30例患者肿瘤均完整切除,经上述3D软件计算的预计切除平均体积为（408.84±177.07）ml,手术中经水测法测得实际平均体积为（399.95±176.15）ml,两者差异无统计学意义（t=1.502,P=0.144）,测量误差率为（6.21±4.73）%.Pearson相关性分析结果提示两者呈正相关（r=0.983,P〈0.05）.结论 3D＋医学影像可视化处理系统是一种较为简便、直观、准确的肝脏体积测量方法,可为临床准确测定肝脏体积及实施复杂肝切除手术提供依据,指导精准肝切除.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.
