本文介绍以Bayes判别为基础的最大似然法,对普通医院较常见的肝硬化、胆管结石、肝癌、壶腹癌和胰腺癌五种肝胆胰疾病,进行电子计算机辅助诊断的研究。 方法 一、病例选择 从医院无选择地收集肝硬化、肝癌、胆管结石各50例,壶腹癌39例和胰腺癌54例,共计243例。除部分肝硬化病例外,全由手术、活检或尸检病理证实。临床诊 This article describes the maximum likelihood method based on Bayesian discriminant, and conducts computer-aided diagnosis of common liver cirrhosis, bile duct stones, liver cancer, ampullary carcinoma and pancreatic cancer. Methods I. Case selection There were 50 cases of liver cirrhosis, liver cancer and bile duct stones, 39 cases of ampullary carcinoma and 54 cases of pancreatic cancer. There were 243 cases. Except for some cases of liver cirrhosis, all were confirmed by surgery, biopsy or autopsy pathology. Clinical diagnosis
