Abstract |
Purpose: Conventional chest X-ray and pulmonary function test cannot sensitively detect inhalation injury.
Bronchoscopy is known to be the gold standard but it is invasive method. We evaluated whether lung
inhalation/perfusion scans can sensitively detect inhalation injury of fire victims. Materials and Methods:
Nineteen patients (male 9, female 10, mean age 31.6 yr) of fire victims were enrolled in this study. Inhalation lung
scan was performed 2 days later after inhalation injury with 99mTc-technegas. Perfusion lung scan was performed 4
days later with 99mTc- MAA (macroaggregated albumin). Follow up lung scans were performed 16 and 18 days later
for each. Chest X-ray was performed in all patients and bronchoscopy was performed in 17 of 19 patients at the
same period. Pulmonary function test was performed in 9 patients. Results: Four of 19 patients showed inhalation
and perfusion defects and one showed inhalation defect but, normal perfusion scan findings. These five patients
with abnormal scan findings showed abnormal bronchoscopic findings and severe respiratory symptoms. On chest
X-ray, 2 of them had pulmonary tuberculosis and one of them showed pulmonary congestion. FEV1/FVC was
abnormal in 3 patients. On the follow up scan, all patients with abnormal initial scan findings showed improved
findings and they had improved clinical state. Conclusion: Inhalation/perfusion lung scans can detect inhalation
burn injury noninvasively in early stage and may be useful in therapeutic decision making and follow up of
patients. (Nucl Med Mol Imaging 2006;40(1):28-32) |
