【摘要】：目的探讨CT灌注联合能谱成像对老年射频消融肺癌术后患者近期疗效的。方法 60例经病理证实的老年肺癌患者,均行射频消融术治疗,并于术前及术后行CT灌注联合能谱成像检查,比较手术前后CT灌注参数值及能谱CT参数值变化,并对比治疗后缓解、复发者CT灌注参数值及能谱CT参数值。结果治疗后CT灌注参数血流量(BF)、血容量(BV)、表面通透性(PS)均低于治疗前(P0.05);能谱CT参数碘含量均低于治疗前(P0.05);缓解组CT灌注参数BF、BV、PS均低于复发组(P0.05);缓解组能谱CT参数碘含量、水含量、CT值均低于复发组(P0.05)。结论 CT灌注联合能谱成像能够客观反映老年肺癌射频消融术治疗前后病灶的灌注程度及血功特点,进而为平均射频消融术的早期疗效提供有利依据。
[Abstract]:Objective to investigate the short-term effect of CT perfusion combined with energy spectrum imaging on elderly patients with lung cancer after radiofrequency ablation. Methods 60 elderly patients with lung cancer confirmed by pathology were treated with radiofrequency ablation. Ct perfusion combined with energy spectrum imaging was performed before and after operation. The changes of CT perfusion parameters and energy dispersive CT parameters were compared before and after operation. The values of CT perfusion parameters and energy spectrum CT parameters in patients with remission and recurrence were compared. Results after treatment, the blood flow volume, blood volume and surface permeability of CT perfusion parameters were lower than that of pre-treatment (P 0.05), the iodine content of energy dispersive CT parameters were lower than that of P0.05, the CT perfusion parameters of remission group were lower than that of relapse group (P 0.05), the iodine content of energy spectrum CT parameters in remission group was lower than that in relapse group. The CT value of water content was lower than that of recurrence group (P 0.05). Conclusion CT perfusion combined with energy spectrum imaging can objectively reflect the degree of focus perfusion and blood work characteristics before and after radiofrequency ablation of lung cancer in the elderly and provide a favorable basis for the early curative effect of the average radiofrequency ablation.
