^(99m)Tc-HL91肺癌乏氧显像临床价值研究
【目的】探讨乏氧组织显像剂99mTc-HL91显像对肺癌诊断价值及与放射治疗前后肿瘤乏氧程度的改变。【方法】选取确诊的肺癌病例41例,非肺癌病例33例为实验组和对照组。实验组于放射治疗前后1,6h行99mTc-HL91肺癌乏氧显像并测定其T/NT比值,放疗后前后4h行CT+SPECT断层显像并测定T/NT比值;对照组行肺部1,6h99mTc-HL91肺癌乏氧显像。【结果】41例肺癌患者治疗前均可见病灶处放射性分布早期增加,血流灌注峰与邻近正常组织比较明显增加。治疗前1、6h平面显像T/NT值分别为1.2024±0.0745,1.4659±0.0820;治疗后1、6分别为1.0895±0.055...
