肝脏肿瘤射频消融术后螺旋CT表现及临床意义

Hepatic tumor treated witht radiofrequency ablation:post-cperative appearance of spiral CT and clinical significance

目的:研究肝肿瘤经皮射频消融治疗后的典型和不典型CT表现并分析其临床意义。方法:52例原发和肝转移瘤患者经皮射频消融术后或术后1月,如果效果显著3月后应用CT三期增强扫描。结果:根据肿瘤灶毁损的程度及时间的变化,消融区影像表现差异大。结论:肝脏肿瘤消融术后螺旋CT扫描,尤其是三期增强扫描对治疗后的疗效及并发症可作出精确的影像诊断,对确定肿瘤残存及复发与否有着重要的作用。

Objective：To observe typical and non typical appearance of spiral CT for hepatic tumor treated with radiofrequence ablation. Methods：52 cases with primary and metastatic liver cancer patiens was performed enhanced spiral CT scan 30d or 60d which effectiveness was significant after radiofrequence ablation.Results： CT features of radiofrequence ablation lesions varied by time length and lesion degree. Conclusion：The spiral CT scanning is vary important to follow up of therapeutic effect and complications of porcutetaneous mdiofrequence ablation in the patiens with hepatic tumor. The enhanced scanning is important for to judge the residue and recto＇fence of lesion, especially three-phase enhanced spiral CT scanning.
