QUANTITATIVE VENTILATION-PERFUSION LUNG SCANS IN INFANTS AND CHILDREN - UTILITY OF A SUBMICRONIC RADIOLABELED AEROSOL TO ASSESS VENTILATION JOURNAL OF PEDIATRICS OBRODOVICH, H. M., Coates, G. 1984; 105 (3): 377-383

Abstract

The quantitative assessment of regional pulmonary ventilation and perfusion provides useful information regarding lung function. Its use in infants and young children, however, has been minimal because of practical and technical limitations when the distribution of ventilation is assessed by radioactive gases. In 16 infants and children we used an inexpensive commercially available nebulizer to produce a submicronic aerosol labeled with 99mtechnetium-diethylenetriamine pentacetic acid to assess ventilation quantitatively, and intravenous injections of 99mtechnetium-labeled macroaggregates of albumin to assess pulmonary perfusion quantitatively. Studies were safely completed in both ambulatory and critically ill patients, including two premature infants who had endotracheal tubes in place for ventilatory support. No sedation or patient cooperation is required. This technique enables any department of nuclear medicine to measure regional pulmonary ventilation and perfusion in infants and children.
