摘要
目的:探讨99mTc-甲氧基异丁基异腈(MIBI)肺阳性显像对肺癌诊断的临床价值。材料与方法:对24例肺肿瘤患者(原发性肺癌 21例,肺良性病变 3例)行99mTc- MIBI肺阳性显像,以早期和城晚期病变处异常核素浓聚为阳性表现。结果:21例原发性肺癌中18例呈阳性改变,3例呈阴性改变;3例肺良性病变均呈阴性改变。99mTc-MIBI肺阳性显像对肺癌诊断的灵敏性为85.7%(18/21),特异性为100%(3/3)。结论:99mTc-MIBI肺阳性显像简便无创,对肺癌的诊断正确率较高,具有重要的临床意义。
Objective: To evaluate the clinical value of 99m Tc-MIBI lung imaging in the diagnosis of lung carcinoma. Materials and methods:Planar lung imagings with 99m Tc - MIBI were performed in 24 patients with lung lesion including 21 cases with primary lung carci- noma and 3 benign lung tumor.The high uptake of MIBI in the site of lesion was considered to be positive.Results: 18 out of 21 patients with primary lung carcinoma showed positive results, while the other 3 patients showed negative results. All of the three patients with benign lung lesion showed negative results. The sensitivity and specificity of 99m Tc - MIBI lung imaging for diagnosing lung carcinoma were 85 .7% (18/21) and 100% (3/3), respectively. Conclusin:99m Tc - MIBI lung imaging is of certain important clinical value for its non - invasiveness, convenience and high accuracy for diagnosing lung carcinoma.
