目的 探讨CT动态增强扫描与MRI 在小肝癌病理分期诊断中的应用价值差 异。方法 选取从2014年1月到2015年12月 的38例经手术病理证实的小肝癌患者，比 较其动态增强CT扫描、MRI扫描资料,分析 动态增强CT和MRI的诊断结果。结果 本组 研究小肝癌患者38例，经增强CT和MRI诊 断，动脉期、门脉期以及延迟期病灶的显 示率分别为90%、70%和80%。结论 增强CT 扫描和MRI在小肝癌的诊断上具有良好的 应用价值，在临床上可联合应用两种方法 对小肝癌进行诊断。

Objective To explore the value of CT enhancement and MRI in the diagnosis of small liver cancer. Methods The data of enhanced CT and MRI in 38 patients with small liver cancers confirmed by operation and pathology from January 2014 to December 2015 were analyzed retrospectively. The diagnostic results of CT enhancement and MRI were analyzed comparatively. Results In this group, 38 patients with small liver cancer were studied and the detection rates were more than 90%,70% and 80%, respectively, during arterial phase, portal venous phase and delayed phase, with CT enhancement scanning and MRI diagnosis. Conclusion CT enhancement scanning and MRI in the diagnosis of small liver cancer had good application value, can be combined to diagnose small liver cancer in clinical application.
