CT和MRI诊断肝内胆管内乳头状肿瘤的价值观察

Diagnostic Value of CT and MRI for Intrahepatic Papillary Neoplasm

目的 探讨并观察计算机断层扫描(CT)和磁共振成像(MRI)诊断肝内胆管内乳头状肿瘤(IPNB)的价值。方法 选取2016年3月~2022年3月在本院收治的65例疑似IPNB患者,对所有患者行CT及MRI检查,分析其影像学特征表现。以术后病理检查结果作为金标准,采用kappa一致性对比分析CT与MRI对IPN的诊断效能。结果 经术后病理检查证实IPNB阳性12例,阴性53例。CT诊断IPNB的灵敏度、特异度、准确率、阳性预测值、阴性预测值和kappa系数值分别为58.33%、96.23%、89.23%、77.78%、91.07%和0.604;MRI诊断IPNB的灵敏度、特异度、准确率、阳性预测值、阴性预测值和kappa系数值分别为75.00%、96.23%、92.31%、81.82%、94.44%和0.736。结论 CT和MRI对IPNB均有较好的诊断价值,影像学特征较为明显。但相较于CT检查,MRI对IPNB的诊断价值更高,值得在临床广泛推广应用。

Objective To explore and observe the diagnostic value of computed tomography(CT)and magnetic resonance imaging(MRI)for intrahepatic papillary neoplasm(IPNB).Methods A total of 65 patients with suspected IPNB admitted to the hospital were enrolled between March 2018 and March 2022.All underwent CT and MRI examinations.The imaging characteristics were analyzed.Taking the results of postoperative pathological examination as the golden standard,the diagnostic efficiency of CT and MRI for IPNB was analyzed by kappa consistency test.Results It was confirmed by postoperative pathological examination that there were 12 cases with IPNB positive and 53 cases with negative.The sensitivity,specificity,accuracy,positive predictive value,negative predictive value and kappa coefficient values of CT and MRI in the diagnosis of IPNB were(58.33%,96.23%,89.23%,77.78%,91.07%,0.604) and(75.00%,96.23%,92.31%,81.82%,94.44%,0.736),respectively.Conclusion Both CT and MRI have good diagnostic value for IPNB.And their imaging characteristics are obvious.However,diagnostic value of MRI is higher for IPNB compared with CT.
