The increase in liver surgery and the proportion of resections done on the margin to postoperative liver failure make preoperative calculations regarding liver volume important. Earlier studies have shown good correlation between calculations done with ImageJ and specimen weight as well as volume calculations done with more robust systems. The correlation to actual volumes of resected liver tissue has not been investigated, and this was the aim of this study.
A total of 30 patients undergoing well-defined liver resections were included in this study. Volumes calculated with ImageJ were compared to volume measurements done after the retrieval of resected liver tissue.
A strong correlation between calculated and measured liver volume was found with sample concordance correlation coefficient (ρc) = 0.9950. The knowledge on the nature of liver resections sets liver surgeons in a unique position to be able to accurately predict the volumes to be resected and, therefore, also the volume that will remain after surgery. This becomes increasingly important with the evolvement of methods to extend the boundaries of liver surgery. ImageJ is a reliable tool to preoperatively assess liver volume.
肝脏手术数量的增加以及在切缘进行的切除术占术后肝衰竭的比例，使得术前计算肝脏体积变得重要。早期研究表明，使用ImageJ进行的计算与标本重量以及使用更强大系统进行的体积计算之间具有良好的相关性。与切除的肝组织实际体积的相关性尚未得到研究，而这正是本研究的目的。
本研究共纳入30例接受明确肝脏切除术的患者。将使用ImageJ计算的体积与切除的肝组织取回后进行的体积测量进行比较。
计算的肝脏体积与测量的肝脏体积之间存在很强的相关性，样本一致性相关系数（ρc）=0.9950。肝脏切除术性质的相关知识使肝脏外科医生处于独特的地位，能够准确预测要切除的体积，从而也能预测手术后剩余的体积。随着扩展肝脏手术边界方法的发展，这一点变得越来越重要。ImageJ是术前评估肝脏体积的可靠工具。
