目的:通过CT引导下肝肿瘤冷冻消融治疗病例的前后影像表现,分析氩氦刀手术后的疗效。方法:通过在螺旋CT引导下,对肝肿瘤进行冷冻消融治疗前后的影像资料进行对比、分析,判断其疗效。结果:9例CT引导下行氩氦刀手术的患者,2个月后复查,发现病变密度较术前病变CT值均减少10HU左右,病变区平扫增强CT扫描均未见强化。结论:CT引导下冷冻消融治疗可显示穿刺针的位置、与周围脏器的毗邻关系以及即时的疗效观察,能快速减少肿瘤负荷,减轻患者痛苦。
OBJECTIVE: To evaluate the CT imaging of the liver tumor by cryoablation and CT angiography, and analyze the curative effect after argon-helium knife surgery. Methods: Comparing and analyzing the imaging data before and after the treatment of liver tumor under the guidance of spiral CT, the curative effect was evaluated. Results: Nine patients who underwent argon-helium knife surgery under CT guidance were reviewed after 2 months. The CT value of lesion density was reduced by 10HU compared with that of preoperative lesion, and no enhancement was observed by contrast-enhanced CT scan. Conclusion: CT-guided cryoablation can show the location of the puncture needle, the adjacent relationship with the surrounding organs and the immediate curative effect. It can rapidly reduce the tumor burden and relieve the patient’s pain.
