摘　　要：目的:探讨99mTc～MIBI肺平面及断层显像对肺恶性病变的诊断及鉴别诊断价值。方法:肘静脉"弹丸"式注射99mTc～MIBI 750MBq,动态采集血流相、血池相(包括10分钟早期摄取相)及2～3小时延迟相图像,计算病变部位早、晚期摄取比值。结果:肺癌病灶与肺良性病变对99mTc～MIBI的摄取有明显差别,以延迟平面显像T/N>1.28及延迟断层显像T/N>1.37为判断标准,其诊断肺部恶性病变的灵敏度分别为78.6%及85.7%,特异性均为88.9%。结论:Tc～MIBI对肺癌有一定的诊断及鉴别诊断价值,断层显像能提高诊断的灵敏度。Objective：To discuss the clinical value of 99mTc-MIBI imaging in differentiating the benign and malignant pulmonary le-sions.Methods：23 patients with pulmonary lesions were examined by 99mTc -MIBI imaging and semiquantitative analysis was per-formed.All the results were compared with pathologic study .Results：The uptake of 99mTc-MIBI was different between malignant and＆amp;nbsp;benign lesions,When the delayed planar imaging T/N rate ＆gt;1.28 and the delayed tomography imaging T/N＆gt;1.37 of malignant lesion was assigned as a threshold for malignant or banign lesions ,The sensitivity was 78.6%and 85.7%,The specificity was 88.9%and 88. 9%.Conclusion：The 99mTc-MIBI lung imaging might be useful for differentiation between malignancy and benign in lung lesions ,The sensitivity of diagnosis may be increased by performed the tomography imaging .
