本文用灰阶、彩阶、彩色多普勒和彩色能量图检查３７例胆道系统肿瘤，按解剖部位分肝内胆管肿瘤、肝外胆管肿瘤和胆囊肿瘤，详细描述超声特征和手术所见等特点并进行分析。胆系肿瘤的早期诊断是较难的，熟悉胆道系统的解剖、仪器的使用、检查方法和临床医学知识，有助于提高超声诊断正确率。 In this paper, 37 cases of biliary system tumors were examined by gray-scale, color-grading, color Doppler, and color energy imaging. Intrahepatic bile duct tumors, extrahepatic bile duct tumors, and gallbladder tumors were divided according to anatomical locations. Features such as ultrasound characteristics and surgical findings were described in detail. And analyze it. The early diagnosis of biliary tumors is difficult. Being familiar with the anatomy of the biliary system, the use of instruments, examination methods, and clinical medical knowledge will help improve the accuracy of ultrasound diagnosis.
