摘　　要：目的:探讨磁共振扩散加权成像对诊断胆管癌的临床应用价值。方法:选取2019年10月—2020年10月河南大学第一附属医院收治的60例疑似胆管癌患者作为研究对象,均行磁共振扩散加权成像诊断和胰胆管水成像诊断。以病理诊断为“金标准”,统计磁共振扩散加权成像、胰胆管水成像诊断胆管癌的诊断结果和诊断效能。结果:60例疑似胆管癌患者,术后确诊阳性33例,阴性27例;采用磁共振扩散加权成像诊断出真阳性32例,真阴性26例;采用胰胆管水成像诊断出真阳性25例,真阴性23例。磁共振扩散加权成像诊断灵敏度96.97%(32/33)、准确度96.67%(58/60),较胰胆管水成像的75.76%(25/33)、80.00%(48/60)高,漏诊率3.03%(1/33),较胰胆管水成像的24.24%(8/33)低,差异有统计学意义(χ^(2)=4.632、0.713、8.086、4.632、0.866,P<0.05)。结论:磁共振扩散加权成像诊断胆管癌诊断,可提高诊断灵敏度、准确度,降低漏诊率,应用价值较高,对指导临床治疗采取针对性干预措施具有积极意义。Objective:To investigate the clinical application value of magnetic resonance diffusion-weighted imaging for the diagnosis of bile duct cancer.Methods:60 patients with suspected bile duct cancer in hospitals from October 2019 to October 2020were selected and all were diagnosed with magnetic resonance diffusion-weighted imaging and pancreaticobiliary water imaging.The pathological diagnosis was taken as the“gold standard”,the diagnostic results and diagnostic efficacy of magnetic resonance diffusion-weighted imaging and pancreaticobiliary water imaging for the diagnosis of bile duct cancer were calculated.Results:In60 patients with suspected bile duct cancer,the diagnosis was confirmed positive in 33 cases and negative in 27 cases after surgery.32 true-positive cases and 26 true-negative cases were diagnosed using magnetic resonance diffusion-weighted imaging,and25 true-positive cases and 23 true-negative cases were diagnosed using pancreaticobiliary water imaging.The diagnostic sensitivity of magnetic resonance diffusion-weighted imaging was higher than that of pancreaticobiliary water imaging,and the leakage rate was lower than that of pancreaticobiliary water imaging,and the difference was statistically significant(χ^(2)=4.632,0.713,8.086,4.632,0.866,P<0.05).Conclusion:Magnetic resonance diffusion-weighted imaging diagnosis of bile duct cancer diagnosis can improve the diagnostic sensitivity,accuracy and reduce the rate of missed diagnosis,which has high application value and is of positive significance to guide clinical treatment with targeted interventions.
