目的 评价CT在肝癌微波消融术 临床疗效中的应用价值。方法 选取近几 年里27例患者已经接受过微波消融治疗的 肝癌患者为研究对象，共52个病灶，通过 观察并分析患者的CT复查图像来确定其在 术后疗效中所起作用和价值。结果 CT平 扫下，肿瘤消融区主要为带状，病灶在术 后表现为以均匀性低密度为主，部分病灶 内可见高密度和等密度。增强扫描表明部 分病灶表现为在动脉期病灶内部和边缘有 部分不规则片状强化区出现，和病灶周边 和内部的结节样强化。结论 CT能快速准 确地判断肝癌患者在微波消融术后的病灶 情况，具有重要的临床应用价值，值得进 一步推广和应用。

Objective Evaluate the application value of CT in the evaluation of clinical efficacy of microwave ablation techniques for liver cancer. Methods Take 27 cases have received microwave ablation of liver cancer patients in recent years for the study objective, a total of 52 lesions. To determine the role and value of CT plays in t the evaluation of clinical efficacy by observing and analyzing the CT review image of patients. Results CT plain scan, the tumor ablation area is a band or circular shape, the lesions showed a low density, high density and density in some lesions. In the enhancement of CT, some lesions showed partial irregular patchy enhancement areas in the arterial phase, and the enhancement of the peripheral and internal nodules. Conclusion CT can quickly and accurately determine the lesion in patients with hepatocellular carcinoma after microwave ablation, has important clinical value and deserves further promotion and application.
