title: [Scintigraphy with 67Ga-citrate and 169Yb-citrate in the diagnosis of lung cancer].
abstract: A scintigraphic study was made of 44 lung cancer patients. At first the diagnosis was made on the basis of an x-ray finding, then it was specified with the help of radioisotope scintigraphy and fibrobronchoscopy with histological examination. 67Ga-citrate and 169Yb-citrate with the activity of 74 MBk were used i. v. for scintigraphy. The scanning was done 72 hrs. after the application of a radionuclide using the magnascanner Picker-500 (USA). In 88.3% of the cases positive scintigraphic results were confirmed histologically as a malignant lung process. A conclusion has been made that both radionuclides are suitable for tumorotropic lung scintigraphy. Owing to its potentialities they can substitute in certain cases for more traumatic roentgenobronchography that also gives radiation exposure.
