Although the clearance of an inhaled nebulised radioaerosol has long been employed as a
measure of lung function, this test has not found favour in nuclear medicine units to the …

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

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 …

To determine whether a portable sodium iodide (NaI) probe could provide a valid measure
of the pulmonary half-life (T1/2) of aerosolized technetium-99m …

Technetium-99m DTPA clearance (99mTc-DTPA) clearance measured by a gamma camera
or a scintillation probe not only reflects epithelial transport, but is also influenced by an …

Several acute and chronic conditions that alter the integrity of the pulmonary epithelium
increased the rate of absorption or clearance into the circulation of small solutes deposited …

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 …

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 …

Age-dependent changes of 99 Tc m-DTPA radioaerosol transpulmonary clearance have
been investigated in 49 healthy volunteers with an age range of 21–63 years. The clearance …

The clearance rate of an inhaled aerosol of a lipophilic complex, 99Tcm-
hexamethylpropyleneamine oxime (99Tcm-HMPAO), was compared with that of a …
