[Scintigraphic radio-spirometry. Methods and indications].

Scintigraphic radio-spirometry combines conventional spirometry with the advantages of a functional isotope technique, thereby providing a clinically useful method for the study of pulmonary function. The advantage of the method consist principally in the ability to estimate physiological values separately for the two lungs, and also for selective portions of each lung. The apparatus, method and quantitative evaluation of the results are discussed in detail and the method is critically evaluated. Indications for radiospirometry are given.
