[Positive scintigraphy in the diagnosis of lung cancer]

Based on the clinico-morphological estimation of scannograms, performed by means of sodium selenite--selenium-75, chloromercury-197 and gallium citrate-67 in 231 patients with tumor (185) and nontumor (46) lung diseases, it was found that the best results were obtained in scannographic visualization of primary tumors of the lung (87%). Positive scintigraphy was found to be of high diagnostic value in recognition of lung cancer proceeding against the background of atelectasis, inflammatory processes and other "disguises" hampering the clinico-roentgenological diagnosis. Positive scintigraphy may be employed in establishing the differential diagnosis between malignant and benign lung tumors.
