Almost any radiopharmaceutical can be nebulised into an aerosol for inhalation. This is routinely performed, for example, with Tc-99m-DTPA for imaging the distribution of ventilation in ventilation-perfusion (VQ) lung scintigraphy. Inhaled Tc-99m-DTPA crosses the blood-gas barrier into pulmonary blood at a rate that can be measured by lung scanning. Clearance rate is increased in inflammatory lung disease as a result of alveolar damage. It is also increased in healthy as well as passive cigarette smokers.

摘要

Almost any radiopharmaceutical can be nebulised into an aerosol for inhalation. This is routinely performed, for example, with Tc-99m-DTPA for imaging the distribution of ventilation in ventilation-perfusion (VQ) lung scintigraphy. Inhaled Tc-99m-DTPA crosses the blood-gas barrier into pulmonary blood at a rate that can be measured by lung scanning. Clearance rate is increased in inflammatory lung disease as a result of alveolar damage. It is also increased in healthy as well as passive cigarette smokers.
