Deposition of Inhaled Particles in Lungs

Nature, 1969
Davies and Muir1 and Dennis2 have reviewed the differences existing in experimental results relating particle size and deposition in the human lung. Data from six independent studies spanning 25 yr fell into two ranges, three groups of workers obtaining much higher values for deposition than the other three for particles greater than 0.5 microns in ...

Dynamics of ’Technegas’ deposited in the lung

Nuclear Medicine Communications, 2001
In tomographic Technegas ventilation studies, the deposited aerosol should be stable. The aim of this study was to investigate the stability of deposited Technegas in severely obstructed patients and in healthy volunteers. Six emphysematous patients and five healthy volunteers were studied. Anterioposterior (AP) and posterioanterior (PA) dynamic images

Abnormal Deposition of Radiostrontium in Lungs

Chest, 1972
A report of unusual deposition of radiostrontium in the lungs is presented. There was clear visualization of both lungs. The possible mechanism is mentioned. The observation may further stimulate investigators to find the exact reason for this.

The Measurement of Antimony Deposits in the Lung

Physics in Medicine & Biology, 1967
The principles of X-ray spectrophotometry are applied to the determination in vivo of antimony deposits in the lungs of industrial workers. The radiation source is Iodine-125, which emits two effectively monochromatic components. The intensity of the beam transmitted through the patient is measured by a scintillation counter and its spectral ...

Deposition of Inhaled Particles in the Lungs

Archivos de Bronconeumología (English Edition), 2012
Inhaled medication is the first-line treatment of diseases such as asthma or chronic obstructive pulmonary disease. Its effectiveness is related to the amount of drug deposited beyond the oropharyngeal region, the place where the deposit occurs and its distribution (uniform or not).

Deposition of Charged Particles on Lung Airways

Health Physics, 1998
The effect of a single electric charge on the efficiency with which ultrafine particles deposit in human airways has been investigated. When inhaled short-lived radon progeny are attached to electrically neutral particles their deposition efficiency is controlled by diffusion. But most ambient particles carry one, or a few, charges.
