目的 探讨磁共振成像对胆管内乳头状肿瘤的诊断价值。方法 收取我院72例胆管内乳头状肿瘤患者，收取时间在 2014年5月10日直至2015年5月1日，并将胆管内乳头状肿瘤患者分为两组，对照组(36例患者实施CT诊断)，观察组 (36例患者实施磁共振成像诊断)，将两组胆管内乳头状肿瘤患者的诊断结果进行对比。结果 观察组胆管内乳头状 肿瘤患者中，阴性患者有5例(其中误诊患者有3例、误诊率为8.33%；漏诊患者有2例、漏诊率为5.56%)、阳性患者 有31例、检出率为86.11%(P＜0.05)。结论 磁共振成像对胆管内乳头状肿瘤患者具有较高的诊断价值，值得应用。

Objective To investigate the value of magnetic resonance imaging in the diagnosis of bile duct papillary tumor. Methods 72 cases of intraductal papillary tumor patients from May 10, 2014 to May 1, 2015 were divided into two groups.The control group (36 patients with CT diagnosis), and the observation group (36 cases underwent magnetic resonance imaging diagnosis),The results of the two groups of patients with intraductal papillary tumors were compared. Results The observation group of intraductal papillary tumor patients, 5 cases of negative patients (of which 3 cases were misdiagnosed, the misdiagnosis rate was 8.33%. 2 cases were misdiagnosed, the misdiagnosis rate was 5.56%), 31 cases of patients, the positive detection rate was 86.11% (P<0.05). Conclusion Magnetic resonance imaging is of high diagnostic value for bile duct papillary tumor and deserves to be applied.
