~(67)镓是回旋加速器产生的呈游离状态的同位素,它和恶性组织有高度亲合力,但和肿瘤组织类型无关。有报告枸橼酸~(67)镓在原发性肺癌中的发现率大于90%,但在活动性肺结核、矽肺、急性感染、尤以新近发展中的结节病等良性病变、也有阳性发现。有人报告58例良性肺部病变的阳性率几近40%。 The ~(67)镓 is a free state isotope produced by a cyclotron, which has a high affinity for malignant tissues, but is not related to the type of tumor tissue. It has been reported that the discovery rate of citric acid ~ (67) plutonium in primary lung cancer is greater than 90%, but positive findings have also been found in active pulmonary tuberculosis, silicosis, acute infections, especially in newly developed benign diseases such as sarcoidosis. . Some reported 58 cases of benign lung lesions with a positive rate of nearly 40%.
