[Pulmonary gammagraphy in children with cystic fibrosis].

An analysis is carried out of the findings from the radioisotopic lung scans of 16 children suffering from cystic fibrosis (CF), 10 boys and 6 girls, with an age range of between 3.5 and 14.2 years and an evolution time of between 1.2 and 9.9 years. The radioisotopic lung scan study shows lung perfusion defects in 14 of the 16 children (87%), the pulmonary vertices being more greatly affected, especially in the left lung (81%). We revised current aspects of radioisotopic lung scanning in paediatrics and evaluated the great importance of this test as a means of detecting CF and its evolution.
