Pulmonary high-resolution CT and radionuclide pulmonary perfusion/ventilation scan in pediatric patients with bronchiolitis obliterans / 中华核医学与分子影像杂志

ABSTRACT

Objective To evaluate the clinical application of pulmonary high-resolution CT (HRCT) and radionuclide pulmonary V/Q scan in pediatric patients with bronchiolitis obliterans (BO).Methods From February 2005 to April 2011,30 BO pediatric patients (18 males,12 females,age range7 months-14 years) in Beijing Children's Hospital Affiliated to Capital Medical University were recruited for pulmonary HRCT and radionuclide pulmonary V/Q scan.Kappa test was used to describe the consistency between "Mosaic perfusion pattern" in pulmonary HRCT and radionuclide pulmonary ventilation abnormalities.Results "Mosaic perfusion patterns" in pulmonary HRCT were showed in 30 cases (100％).Ventilation defects were found in 27 cases (90.0％) and perfusion defects in 25 cases (83.3％).The Kappa value between "Mosaic perfusion pattern" in pulmonary HRCT and pulmonary ventilation defects was 0.201 (0.1340.268),which was slightly higher than that between "Mosaic perfusion pattern" in pulmonary HRCT and pulmonary perfusion defects (0.147 (0.061-0.233)),but there was no statistical difference.Conclusions " Mosaic perfusion pattern" in pulmonary HRCT cannot distinguish between pulmonary ventilation and perfusion abnormalities.V/Q scan could be a useful tool for BO.
