利用数字图像处理系统和“三维信息提取与三维图像重建”的方法,通过肝脏 CT 断层影像,成功地重建了活体肝脏三维图像,并测出活体肝脏体积。为排除体格差异,再根据体表面积,求出每单位体表面积的肝脏体积。临床应用42例,其中非肝硬化组8例,均值为773.88±69.17cm~3/m~2;肝炎后肝硬化组34例,均值为493.72±102.50cm~3/m~2。两组均值的差异显著(P<0.001)。肝炎后肝硬化组中,各级肝功能的肝体积无统计学差异(P>0.05)。肝体积大于400cm~3/m~2者与小于400cm~3/m~2者的术后顺利康复率差异显著(P<0.01)。
Using the digital image processing system and the “three-dimensional information extraction and three-dimensional image reconstruction” method, three-dimensional images of living liver were successfully reconstructed by liver CT tomography, and living liver volume was measured. To exclude physical differences, the liver volume per body surface area was determined based on the body surface area. Clinical application of 42 cases, including 8 cases of non-cirrhosis group, the average was 773.88±69.17cm~3/m~2; 34 cases of posthepatitic cirrhosis group, the mean value was 493.72±102.50cm~3/m~2. The difference between the two groups was significant (P < 0.001). In the post-hepatitis cirrhosis group, there was no significant difference in liver volume at all levels of liver function (P>0.05). There was a significant difference in the recovery rate of patients with liver volume greater than 400cm~3/m~2 and less than 400cm~3/m~2 (P<0.01).
