胆管内超声诊断胆管细胞癌的研究进展

Research progress on intraductal ultrasonography in the diagnosis of cholangiocarcinoma

对胆管癌尤其早期胆管癌的诊断仍是当前临床诊疗中的难题。传统的US、CT、MRI、MRCP不能确定胆管扩张的病因、病灶的位置或病灶的范围。胆管内超声(IDUS)对胆管癌的诊断具有重要价值,已逐渐被应用于对胆管狭窄性疾病的诊断。

The diagnosis of bile duct carcinoma, especially early bile duct carcinoma, remains a challenge. Traditional US, CT, MRI, and MRCP can not determine the cause of bile duct expansion, position or range of the lesion. Intraductal ultrasonography （IDUS） is important to the diagnosis of cholangiocarcino- ma, having gradually been applied to the diagnosis of bile duct stricture disease.
