磁共振胰胆管造影联合弥散加权成像在恶性胆道梗阻中的诊断价值研究

Study on the diagnostic value of magnetic resonance cholangiopancreato-graphy combined with diffusion weighted imaging in malignant biliary obstruction

目的探究磁共振胰胆管造影(MRCP)联合弥散加权成像(DWI)在恶性胆道梗阻中的诊断价值。方法选取2021年4月至11月河北省涿州市医院收治的100例疑似恶性胆道梗阻患者,分别采用MRCP、MRCP联合DWI进行诊断,以病理结果为金标准,评估两种诊断方案的准确性。结果100例患者中恶性59例,良性41例。59例恶性病变中包括壶腹癌11例,胰头癌23例,胆管癌25例。MRCP诊断结果的准确性、灵敏度、特异度分别为91.00%、84.75%、95.12%;MRCP联合DWI诊断的准确性、灵敏度、特异度分别为98.00%、96.61%、100.00%。结论相较于单纯MRCP检查,MRCP联合DWI在恶性胆道梗阻诊断中有着更高的应用价值,可作为恶性病变鉴别诊断的参考指标。

Objective To explore the diagnostic value of magnetic resonance cholangiopancreatography(MRCP)combined with diffusion weighted imaging(DWI)in malignant biliary obstruction.Methods A total of 100 patients with suspected malignant biliary obstruction treated in Zhuozhou City Hospital of Hebei Province from April to November 2021 were selected.MRCP and MRCP combined with DWI were used for diagnosis respectively.The pathological results were used as the gold standard to evaluate the accuracy of the two diagnostic protocols.Results Among the 100 patients,59 were malignant and 41 were benign.The 59 malignant lesions included 11 cases of ampullary carcinoma,23 cases of pancreatic head carcinoma,and 25 cases of cholangiocarcinoma.The accuracy,sensitivity,and specificity of MRCP were 91.00%,84.75%,and 95.12%respectively;the accuracy,sensitivity,and specificity of MRCP combined with DWI were 98.00%,96.61%,and 100.00%respectively.Conclusion Compared with MRCP alone,MRCP combined with DWI has higher application value in the diagnosis of malignant biliary obstruction,and can be used as a reference index for the differential diagnosis of malignant lesions.
