CT、MRI对胆囊癌转移途径的评价与分析

Evaluation of CT and MRI Imaging on the Metastasis Routes of Gallbladder Carcinoma

目的:探讨原发性胆囊癌及其转移途径的CT、MRI表现,评价CT结合MRI诊断胆囊癌转移途径的优势及价值。方法:回顾性分析经手术病理证实的36例胆囊癌并伴有转移的患者,将其CT、MRI表现总结分析,研究两者相结合对胆囊癌转移途径的诊断价值。结果:胆囊癌转移途径主要分为直接侵犯、淋巴转移、血行转移、胆管内转移及腹腔内种植转移。CT、MRI的结合应用对其原发灶及转移灶的诊断有极高的准确性。结论:CT、MRI相结合能较为准确地对原发灶及转移灶进行诊断及分型,并能准确地描述和评价胆囊癌的扩散程度及浸润范围。

Objective：To evaluate the effects of CT and MR imaging in assessing the metastasis routes of primary Gallbladder carcinoma,especially in assessing the advantages of combining CT with MRI in diagnosis.Methods：Retrospectively studied 36 patients with metastasis of primary Gallbladder carcinoma confirmed pathologically. All patients were examinated with CT and MRI,and the imaging results were jointly evaluated,and assessed in the carcinoma metastasis routes. Results：The diagnosis of primary gallbladder carcinoma and metastasis lesions was improved by combining CT with MRI. The metastasis routes of gallbladder carcinoma were found and divided into direct invasion,lymph metastasis,hematogenous metastasis,metastasis inside bile duct and metastasis inside abdomen. Conclusion：The CT combined with MR imaging improve the diagnosis of primary gallbladder carcinoma and metastasis as well as assess the proliferation and infiltration of cancer lesions.
