Radioaerosol inhalation lung imaging for the diagnosis of chronic obstructive pulmonary diseases in Thailand. Final report for the period 10 December 1987 - 15 December 1993

摘要

The radionuclide pulmonary function studies such as aerosol inhalation lung imaging, mucociliary clearance and pulmonary epithelial were developed and studied in normal and chronic obstructive pulmonary disease. The results of the aerosol inhalation lung imaging in 71 cases of COPD revealed that the aerosol inhalation lung scan was the most sensitive test for the diagnosis of early COPD as compared to the chest X-ray, vascular perfusion lung scan and spirometric test (% FEVI). The aerosol and perfusion lung scan were also performed in 21 cases of carcinoma of lung who had been treated with external radiation or chemotherapy. The result of study revealed 5 patients died during treatment, 5 patients were slightly improved, no significant change was detected in 10 cases and deterioration was found in one patient. The lung scintigraphy was studied in 15 cases of well differentiated carcinoma of thyroid with pulmonary metastasis who had I-131 treatment. The study showed that the radioactive iodine treatment dose had minimal effect on the post treatment lung imaging study. The perfusion and aerosol study in 15 cases of operated patients revealed no evidence of pulmonary embolism in post operative study. Abnormal vascular disease or pulmonary embolism was observed in one patient preoperatively. 12 refs, 13 figs, 13 tabs. (Atomindex citation 26:052712)
