[Gammagraphy with gallium-67 citrate in the diagnosis of pulmonary tuberculosis]

The reception of Gallium Citrate 67 (C. de Ga-67) has been studied in 27 patients with active pulmonary TBC shown bacteriologically. The findings of the gammagraphy with C. de Ga-67 have been compared with those of the simple thorax radiology. We have objectified 96% sensitivity in the examination of the tuberculous lesions by isotopic techniques. These have shown, as well, a high performance in the detection of active tuberculous areas at hiliar, mediatinic and extrathoracic level, greater than that of the simple radiography, as well as to evaluate the activity of apparently residual lesions in the thorax radiography. We conclude that the gammagraphy with C. de Ga-67 is a bloodless method which complements radiology in the diagnosis of activity, extension and location of pulmonary tuberculosis.
