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 benign lesions,When the delayed planar imaging T/N rate >1.28 and the delayed tomography imaging T/N>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 .
