Healthy and pathological hepatic volumetry can be of great interest in Liver pathology and treatment. We studied the hepatic segmentation in order to verify if it is possible to estimate the volume of one lobe, when the volume of the other lobe or the total liver is known.
We studied 50 normal hepatic angiotomographies. For each exam and using the Couinaud classification, we measured the total hepatic volume, the right lobe, the left lobe and the caudate lobe volumes. We used a software called "Hepato" developed in order to quantify automatically CTScan images of the liver. We performed a linear regression analysis (least squares method) and calculated the determination coefficient to study the correlation between the different volumes.
The mean total hepatic volume was 1497 cm3. We obtained for the right lobe 1231 cm3, 226 cm3 for left lobe, and 39 cm3 for the caudate lobe. Moreover there was a weak correlation between these volumes.
Exact volume estimation of an hepatic lobe in one patient can not be obtained from the total hepatic volume. However, theses volumes can only be measured from three-dimensional images. Since classical image editing tools are time request, it becomes impossible to utilize them in a clinical routine to get the different volumes of the Liver. Thus, a software dedicated for liver parenchyma recognition is necessary.
健康肝脏和病变肝脏的体积测量在肝脏病理学及治疗中具有重要意义。我们研究肝脏分段，以验证当已知另一叶或全肝体积时，是否有可能估算某一叶的体积。
我们研究了50例正常肝脏血管造影。对于每次检查，使用库尼亚德分类法，我们测量了全肝体积、右叶、左叶和尾状叶的体积。我们使用一款名为“Hepato”的软件，该软件专为自动量化肝脏CT扫描图像而开发。我们进行了线性回归分析（最小二乘法）并计算决定系数，以研究不同体积之间的相关性。
全肝平均体积为1497立方厘米。右叶体积为1231立方厘米，左叶为226立方厘米，尾状叶为39立方厘米。此外，这些体积之间存在弱相关性。
无法从全肝体积准确估算某一患者肝脏一叶的体积。然而，这些体积只能从三维图像测量。由于传统图像编辑工具耗时，在临床常规中利用它们获取肝脏不同叶的体积变得不可能。因此，需要一款专门用于肝实质识别的软件。
