自从1969年Edwards等报道~(67)Ga在何杰金氏病的病灶中大最摄取以来,现对恶性肿瘤已广泛应用~(67)Ga做闪烁显像诊断。尤其~(67)Ga闪烁检查对肺癌的诊断更为有效。但存在下述问题:①对小肺癌(直径约3.0cm以下的病灶)检出困难;②不能鉴别活动性炎症等缺点。为此,作者对胸部X线摄影在肺野有异常阴影,难于鉴别良、恶性的病例,试用~(67)Ga的摄取率对小肺癌进行了检测。病例选择对象是,用X线和断层摄影,对肺野病灶小于3厘米且鉴别良,恶性有困难者。
Since 1969, Edwards et al. reported that ~(67)Ga was most frequently taken up in lesions of Hodgkin’s disease, ~(67)Ga scintigraphy has been widely used for the diagnosis of malignant tumors. Especially ~(67)Ga scintigraphy is more effective in the diagnosis of lung cancer. However, there are the following problems: 1 It is difficult to detect small-size lung cancer (lesions less than 3.0 cm in diameter). 2 Disadvantages such as active inflammation cannot be identified. For this reason, the authors had abnormal shadows in the lung fields in chest radiographs, and it was difficult to distinguish between benign and malignant cases. The uptake rate of ~(67)Ga was used to detect small lung cancer. The object of the case selection was X-ray and tomography. The lesions were less than 3 cm in the lung field and were difficult to differentiate.
