肺部良、恶性病变的术前鉴别诊断,尚无既特异又灵敏的方法。因此,寻找一种灵敏度高,特异性强的肺癌阳性显像剂,是近年来人们所关注的课题。Ga显像技术自60年代末用于临床以来,其对肺癌的诊断价值越来越受到重视。但各家报道的结果不尽一致。1990年5月～1992年1月,我科共对58例肺部疾病患者作了Ga—枸橼酸镓亲肿瘤显像,现将结果报道如下。 1 资料与方法 There are no specific and sensitive methods for preoperative differential diagnosis of benign and malignant lung lesions. Therefore, the search for a high-sensitivity, high specificity lung cancer positive imaging agent is a subject of concern in recent years. Since the Ga imaging technology was used clinically in the late 1960s, its diagnostic value for lung cancer has received increasing attention. However, the results of various reports are not consistent. From May 1990 to January 1992, a total of 58 patients with pulmonary diseases were presented with Ga-bismuth gallate pro-tumor imaging. The results are reported below. 1 Materials and Methods
