^(99m)Tc(Ⅴ)-DMSA 及 ^(99m)Tc-MIBI 肺显像诊断原发性肺癌的应用研究

Clinical study on primary lung cancer with 99m Tc(Ⅴ)-DMSA and 99m Tc-MIBI imaging

对３０例原发性肺癌患者分别应用９９ｍＴｃ（Ⅴ）－ＤＭＳＡ及９９ｍＴｃ－ＭＩＢＩ显像。结果表明：９９ｍＴｃ（Ⅴ）－ＤＭＳＡ、９９ｍＴｃ－ＭＩＢＩ敏感度分别为９０％、７６．７％。两者结合显像阳性率为９６．７％。鳞状上皮细胞癌对９９ｍＴｃ（Ⅴ）－ＤＭＳＡ及９９ｍＴｃ－ＭＩＢＩ摄取程度比其它类型的肺癌高。

Primaty lung cancer was studied by 99m Tc(Ⅴ)-DMSA and 99m Tc-MIBI imaging in 30 cases. The results showed that the sensitivity of 99m Tc(Ⅴ)-DMSA and 99m Tc-MIBI was 90% and 76.7% respectively, the positive rate of combined imaging was 96.7%. Also the uptake ratio of squamous-cell carcinoma was higher than other types of primary lung cancer in both 99m Tc(Ⅴ)-DMSA and 99m Tc-MIBI.
