Variations in the intensity of a beam of radiation emerging from the thorax reflect changes in
the mass of a core of tissue lying between the source and the detecting unit. The theoretical …

SPECT images were developed to accurately evaluate perfusion impairment in smokers' …

MATERIALS AND METHODS Nine male volunteers provided a normal control group: five
aged 21-25 yr and four aged 30-34; none of these had a history of tobacco smoking. In …

The purpose of this study was to evaluate the effects of gravity and lung volume on regional
pulmonary perfusion using technetium-99m macroaggregated albumin (99m Tc MAA) single …
