目的：利用放射性核素肝胆动态显像对肝胆系统的定量分析指标研究，定量地反映肝细胞、胆道系统的病理改变。方法：使用ＳＰＥＣＴ仪对２６例胆道手术病人术前后作９９ｍＴｃ－亚氨基二乙酸（ＥＨＩＤＡ）肝胆动态显像，并与正常对照组４３例对比研究。结果：肝胆动态图像经处理后可得到以下各参数：肝射胆分数，肝摄胆Ｔ１／２、排胆Ｔ１／２、肠道显影时间，从而可评价手术的效果，而且根据肠显影时间和图像观察，可评价吻合口状态，利于并发症的诊断。结论：９９ｍＴｃ－ＥＨＩＤＡ肝胆动态显像将图像和各参数结合起来，大大地提高了对肝胆系统疾病的诊断的准确性
OBJECTIVE: To quantitatively analyze the pathological changes of hepatocytes and biliary tract by quantitative analysis of liver and gallbladder system using radionuclide dynamic imaging of liver and gallbladder. Methods: Twenty-six patients with biliary tract surgery underwent 99mTc-iminodiacetic acid (EHI-DA) dynamic imaging of liver and gallbladder with SPECT before and after operation, and compared with 43 normal controls. Results: After treatment of liver and gallbladder dynamic images, the following parameters were obtained: hepatobiliary fraction, liver gallbladder T1 / 2, gall bladder T1 / 2, intestinal development time, which can evaluate the effect of surgery, and according to intestinal development time and Image observation, can evaluate the anastomotic state, which will help the diagnosis of complications. Conclusion: 99mTc-EHIDA dynamic imaging of liver and gallbladder combined the images and parameters, greatly improving the diagnostic accuracy of hepatobiliary diseases
