In a prospective study of 34 patients with histologically proven bronchogenic carcinoma, 67Ga scanning of the chest was used to screen for mediastinal involvement. Mediastinal scans and pathologic findings were in agreement in 27 patients. Two patients had false-negative scans and 5 had positive scans but no evidence of mediastinal tumor. These results indicate a sensitivity of 89%, a specificity of 66.6%, an accuracy of 77% for positive scans, and an accuracy of 83% for negative scans. Overall correlation between 67Ga scanning of the chest and mediastinal-tumor involvement is statistically significant (P = 0.003).
在一项对34例经组织学证实为支气管源性癌患者的前瞻性研究中，采用胸部67镓扫描来筛查纵隔受累情况。27例患者的纵隔扫描结果与病理检查结果相符。2例患者扫描结果为假阴性，5例患者扫描结果为阳性但无纵隔肿瘤证据。这些结果表明，阳性扫描的敏感性为89%，特异性为66.6%，准确率为77%，阴性扫描的准确率为83%。胸部67镓扫描与纵隔肿瘤受累之间的总体相关性具有统计学意义（P = 0.003）。
