67Ga scintigraphy is frequently used to screen pulmonary malignant tumors. We recently re-evaluated the diagnostic significance of 67Ga scintigraphy by comparing 67Ga scintigraphy (planar image) and chest CT in assessing the T and N factors of tumors. The study included 13 cases of squamous cell carcinoma and 15 cases of adenocarcinoma. In all cases, the diagnosis was histologically verified by surgery. The analysis revealed that 67Ga scintigraphy better demonstrated the T factor and stage of squamous cell carcinoma than in adenocarcinoma. The true positive rate of N factor did not significantly differ between chest CT (60% for squamous cell carcinoma and 86% for adenocarcinoma) and 67Ga scintigraphy (67% and 88%, respectively).67Ga scintigraphy is considered to be a useful preoperative examination for non-small cell lung cancer, because it provides additional information for preoperative evaluation concerning surgical indications if it is applied to selected cases with sufficient knowledge about limitations concerning its imaging abilities.
