Alveolar epithelial permeability in patients with primary spontaneous pneumothorax as determined by Tc-99m DTPA aerosol scintigraphy.
PURPOSE Primary spontaneous pneumothorax (PSP) occurs subsequent to a disruption in the continuity of visceral pleura and escape of air into the pleural space. The cause of PSP is most often the rupture of subpleural blebs or bullae. It is usually difficult to detect evidence of pulmonary pathology. The purposes of the present study were (1) to investigate the changes of pulmonary alveolar epit...
متن کاملAlveolar permeability in HIV antibody positive patients with Pneumocystis carinii pneumonia.
Pulmonary permeability was assessed using the technique of 99mTc (technetium-99m) diethylene triamene pentacetic acid (DTPA) aerosol transfer in 10 patients who had antibodies to human immunodeficiency virus (HIV) and were non-smokers and in 20 HIV antibody positive smokers. Five patients had Pneumocystis carinii pneumonia (PCP) proved by transbronchial lung biopsy; four were non-smokers and on...
متن کاملDetection of alveolar epithelial injury by 99mTC-DTPA radioaerosol inhalation lung scan following blunt chest trauma.
DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assesss the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or i...
متن کاملMonitoring of renal function using 99mTc-DMSA and 99mTc-DTPA scintigraphy in patients with spinal cord injury.
AIM The aim of this study was to assess the degree of alterations of renal function by using 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA) and 99m-technetium diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) scintigraphy in spinal cord injury (SCI) patients. MATERIAL AND METHODS Twenty-two consecutive SCI (15 paraplegic and 7 tetraplegic) patients (mean age: 49.1±13.4 years) who had n...
متن کاملTransfer of 99mTc DTPA and bronchoalveolar lavage findings in patients with asymptomatic extrinsic allergic alveolitis.
An investigation was performed to determine whether symptom free patients with previously diagnosed extrinsic allergic alveolitis had signs of inflammation in the lung. Pulmonary clearance of inhaled technetium-99m labelled diethylene triamine penta-acetic acid (DTPA) was measured in seven patients with a history of extrinsic allergic alveolitis but with no symptoms at the time of the study and...
