Inter-scan repeatability of CT-based lung densitometry in the surveillance of emphysema in a lung cancer screening setting

European Journal of Radiology, 03/16/2012

Lung densitometry protocols produce different levels of repeatability for an asymptomatic population, each being influenced by inspiratory level to a different degree. For surveillance of emphysema in a lung cancer screening setting, RA970 and Perc1 may be the most suitable protocols, in which the application of VA needs to be included as a critical part.
