During the last few years a number of factors affecting the measurement of the rate of
absorption of 99m Tc-DTPA across the alveolar-capillary membrane have been identified …

The pulmonary clearance rate of aerosolized and deposited [99mTc] DTPA is used to
assess pulmonary epithelial permeability to solutes. To evaluate whether it is necessary to …

Soluble radioaerosols such as technetium-99m diethylene triamine pentacetate (DTPA)
permit simple quantitative studies of alveolar-capillary permeability to be performed, since …

The rate at which inhaled aerosol of 99m Tc-diethylenetriamine pentacetate (DTPA) leaves
the lung by diffusion into the vascular space can be measured with a gamma camera or …

The clearance rate of 99mTc-DTPA deposited in the lung by inhalation has been used as an
index to measure lung epithelial permeability. To determine if differences exist between …

During the last decade it has been customary to estimate pulmonary epithelial permeability
(P‐P) as the pulmonary clearance of inhaled nebulized 99mTc‐DTPA from a time‐activity (t …

The lung clearance of technetium-99m diethylenetriamine penta-acetic acid (99mTc-DTPA)
is a measure of respiratory epithelial permeability. Many factors may contribute to the wide …

The anatomy and physiology of the pulmonary epithelial barrier are briefly described, and
methods of measuring permeability of the barrier to solutes are outlined, including findings …

Pulmonary clearance of small droplet 99mTc-DTPA radioaerosol was studied in 100
patients (12 normal subjects, N; 10 asymptomatic healthy smokers, FA; 31 patients with …

The early diagnosis of diffuse infiltrative lung disease (DILD) is important in prognosis and it
is necessary to develop a noninvasive, inexpensive, and rapid diagnostic tool for suspected …
