[Combined 113Xe/99mTC human serum albumin microspheres lung scintigraphy in children with recurrent and chronic bronchitis].

A total of 117 children with recurrent and chronic bronchitis aged from 2 months to 16 years were subjected to combined ventilation-perfusion scan of the lungs with 133Xe-gas and 99mTc-HAM. It served as a screening before bronchological examination with the aim to get a more exact indication for bronchography which leads to a higher stress in children because of anaesthesia and radioscopy. Due to combined lung scan, the number of bronchological examinations could be reduced from 109 in 1984 to 79 in 1985 and even to 54 in 1986. Among the 117 children suffering from bronchitis, we found normal scans in 16 cases, perfusion defects in 59 cases, combined ventilation-perfusion defects in 41 cases and one case showed a pure ventilation defect. The lung scan should be applied in the framework of bronchopulmonary standard diagnosis.
