IQQA(R)-Liver分析系统对精准肝切除术术前评估的意义

The significance of IQQA(R)-Liver analysis system for preoperative evaluation of precise liver resection

目的探讨IQQA(R)-Liver影像分析系统评估肝静脉对精准肝切除术的指导作用。方法选择62例接受精准肝切除术的患者(年龄40～60岁)为研究对象。每根肝静脉分支都用IQQA(R)-Liver影像分析系统和GEAW4.4工作站显示结果进行评估,所有肝静脉图像成像质量被划分成差、一般、较好和好4个层次,分别采用0、1、2、3分的形式计量。并对两者制作肝静脉过程所消耗的时间进行对照。结果两种后处理系统都可以观察到肝静脉的主要分支,两者之间图像质量没有显著性差异(P>0.05)。肝右静脉单独汇入下腔静脉,肝左静脉和肝中静脉先汇合后再注入下腔静脉占84.7%(50/59);肝右静脉、肝中静脉及肝左静脉分别单独汇入下腔静脉占15.3%(9/59)。重建肝静脉所消耗的时间IQQA(R)-Liver分析系统和GEAW4.4工作站分别为(3.3±0.8)min和(38.6±6.2)min,两者之间差异有统计学意义(P<0.001)。结论 IQQA(R)-Liver分析系统较传统AW4.4工作站在肝静脉图像后处理方面能非常明显提高效率。而在肝静脉主要分支显示能力上没有差异。这项新技术对于精准肝切除术术前评估有意义。

Objective To assess the guiding effect of the IQQA （R） -Liver image analysis system used for evaluating hepatic vein on the precise liver resection. Methods Sixty-two patients （ aged 40-60 years） received precise liver resection were selected as research objects. All hepatic vein branches were post-processed and evaluated with IQQA （R） -Liver image analysis system and GE AW4.4 workstation. The images of the hepatic veins were divided into four levels based on the image quality： poor, general, good and excellent respectively, which were respectively counted by 0,1,2,3 points. The time consumption of the post-processing was Compared between IQQA（ R）-Liver image analysis system and GE AW4.4 worksta- tion. Results The main branches of hepatic veins can all be observed by the two pest-processing system. There was no significant difference in the image quality between the two post-processing system （ P 〉 0. 05 ）. The number of right hepatic vein alone importing inferior vena cava and left hepatic vein and middle hepatic vein converging before importing the inferior vena cava accounted for 84.7% （50/59） ,and the number of right hepatic vein,middle hepatic vein and left hepatic vein respectively importing inferior vena cava accounted for 15.3% （9/59）. There was significant difference between IQQA （R）-Liver analysis system and GE AW4.4 workstation in the time consumption of hepatic vein reconstruction [ （ 3.3 ±0.8） rain and （38.6 ±6.2 ） min,P 〈 0.01 ]. Conclusions IQQA （R）-Liver analysis system can significantly promote the efficiency in the post-processing of hepatic vein reconstruction compared with AW 4.4 workstation, but there is no difference in the image quality between the two methods. IQQA（ R）-Liver analysis system would be helpful for the preoperative evaluation of the precise liver resetion.
