【摘要】 目的:对比多层螺旋CT(MSCT)动态增强扫描与磁共振(MRI)肝脏特异性对比剂增强在早期肝癌诊断中的应用效果。方法:选取我院疑似肝癌患者78例,均行MSCT动态增强扫描与MRI肝脏特异性对比剂增强检查,以病理诊断作为"金标准",对比两种检测方式的敏感性、准确率、特异性。结果:病理诊断结果为78例疑似肝癌患者中阳性48例,阴性30例;MRI肝脏特异性对比剂增强诊断肝癌敏感性为93.75%(45/48)、准确率为89.74%(70/78)、特异性为83.33%(25/30),比MSCT动态增强扫描高(P<0.05)。结论:与MSCT动态增强扫描对比,MRI肝脏特异性对比剂增强在早期肝癌诊断中敏感性、准确率、特异性较高,可为临床早期诊断提供可靠的参考依据。更多还原

【Abstract】 Objective: To compare the application effect of multi-slice spiral CT(MSCT) dynamic enhancement scan and magnetic resonanceImaging(MRI) liver specific contrast agent enhancement in the diagnosis of early liver cancer. Methods: 78 patients with suspected liver cancer in our hospital were selected, all of them underwent MSCT dynamic enhancement scan and MRI liver specific contrast agent enhancement. Using pathological diagnosis as the "gold standard", the sensitivity, accuracy and specificity of the two detection methods are compared. Results: The pathological diagnosis results were 48 positive and 30 negative among 78 patients with suspected liver cancer; MRI liverspecific contrast agent enhancementdiagnosetheliver cancer with the sensitivity of 93.75%(45/48), the accuracy of 89.74%(70/78), and the specificity of 83.33%(25/30), which is higher than the MSCT dynamic enhancement scan(P<0.05). Conclusion: Compared with MSCT dynamic enhancement scan, the sensitivity,accuracy, and specificity of MRI liverspecific contrast agent enhancement in the diagnosis of early liver cancer is higher.It can provide a reliable reference for early clinical diagnosis.更多还原
