| 摘 要： | 目的:比较CT与MRI对于胰岛素瘤定位诊断的临床价值.资料和方法:2006-09～2009-12临床疑诊胰岛素瘤患者共28名,均接受CT和MRI检查.以手术病理及临床定性诊断为对照标准,对比分析两种检查方式对胰岛素瘤的定位诊断效能.结果:19名患者经手术病理证实胰岛素瘤19例,其中CT检出12例,MRI检出16例.9名临床定性诊断除外胰岛素瘤的患者CT和MRI检查均为阴性.CT对胰岛素瘤术前定位诊断的敏感度、特异度、阳性预测值及阴性预测值分别为63.2%(12/19)、100%(9/9)、100%(12/12)及56.3%(9/16),MRI上述数值分别为84.2%(16/19)、100%(9/9)、100%(16/16)及75%(9/12).两种检查方法对胰岛素瘤定位诊断敏感度、阴性预测值间的差异无统计学意义(P=0.1336,P=0.4343).结论:CT和MRI对胰岛素瘤定位诊断的价值无明显差异.

| Abstract: | Purpose To compare the diagnostic efficiency between computed tomography(CT) and magnetic resonance imaging(MRI) in localization of insulinoma.Materials and Methods From September 2006 to December 2009,twenty-eight patients With clinical suspected insulinoma underwent CT and MRI examination.Using pathologic results and clinical characterization as the reference standard,diagnostic efficiency of CT and MRI were compared.Results 19 cases were pathologically proved.12 cases had positive CT scans,and 16 cases h... |
