摘　　要：目的探讨采用心脏专用软件包（Argus）测量肝脏体积的可行性。方法回顾性分析32名肝移植供体行术前常规MR扫描及钆贝葡胺增强后容积内插值体部检查（VIBE）序列扫描，容积数据传入后处理工作站并行MPR。首先在媒体浏览器模式下诸层绘出肝脏外形轮廓并分别计算出全肝体积、含肝中静脉（MHV）右半肝体积及不含MHV右半肝体积，并计算时间。然后将相同数据导入Argus软件计算全肝体积、含MHV右半肝体积及不含MHV右半肝体积，并计算所用时间。采用直线相关分别对比手工测量、Argus测量与术中测量肝右叶体积的相关性；采用配对t检验对比2种检查方法所需时间的差异。结果32名供肝者右半肝体积手工测量、Argus测量和术中测量结果分别为（813±187）、（807±181）和（713±137）mm^3，手工测量、Argus测量和术中测得的右半肝体积间均有相关关系（r值分别为0．884和0．897，P值均〈0．05）。手工和采用Argus测量所需时间分别为（44．3±2．7）和（12．2±1．0）min，差异有统计学意义（t=76．39，P〈0．05）。结论Argus软件与手工测量相比，准确性高，并且省时、简便，具有很高的临床应用价值。Objective To investigate the feasibility of measuring liver volume with Argus method. Methods Thirty-two healthy liver transplant donor candidates underwent liver MRI on a 3.0 T MR unit. Volume interpolated body examination （VIBE） was performed after the administration of gadobenate dimeglumine. The VIBE data was transferred to the diagnostic workstation, and then multiple planar reconstruction （MPR） images were acquired. Firstly, two observers manually drawn the liver shape and calculated three volumes： the whole liver volume and right lobes volumes include middle hepatic vein （MHV） and exclude MHV, respectively. Secondly, the same data was transferred to Argus software, calculated that three volumes. Each measurement time was recorded. Actual graft volume（ the right lobe）was measured during surgery. The correlation between right lobes volume of two measurements and actual graft volume was analyzed. The time needed for Argus and that needed for manual method were compared with paired t test. Results The right lobe volumes measured by Argus, manually and surgery method were （813 ± 187）, （807 ± 181 ） and （713 ± 137） mm^3, respectively. Argus method and manual method showed good correlation with surgery method, and the correlation coefficients were 0. 897 （ Argus method ） and 0. 884 （manual method）, respectively. The time for manual method and Argus method were （44. 3 ± 2. 7 ） and（ 12. 2± 1.0）min, respectively. There was significant difference between Argus and manual methods （t =76. 39,P 〈 0. 05 ） . Conclusion Compared with manual method, use of the Liver volumetric measurement by Argus software not only correlated well with Actual graft volume, but also saves time. Argus has potential clinical value for volumetric measurement in living liver transplant donors.
