Overview
Brief Summary
The noncontrast-enhanced chest computed tomography (CT) is an emerging diagnostical tool in patient with chronic obstructive pulmonary disease (COPD). As shown in previous studies and pointed out by the Fleischner society, an additional scan in expiration reflects the pathophysiology of this complex disease better and extends the clinical information of the CT.
Nevertheless, this scan is leading to an increase in radiation dose. But currently it is unclear if this increased radiation dose is proportional to the additional clinical value when compared to inspiration-only protocols. Therefore, the aim of this study was to compare the organ specific radiation doses of a combined inspiration-expiration CT on a 3rd generation dual-source scanner with noncontrast-enhanced chest CTs of two clinical routine scanners. Therefore, the radiation doses of nearly 2000 chest CTs have been evaluated.

Outcomes
Primary Outcomes
organ specific radiation doses
Time Frame: The organ dose calculations have been performed retrospectively. Therefore, the time frame is variable. The time set for the final outcome calculations was September 2017. Therefore, the time frame varies between 3 years and 1 week.
Organ specific radiation doses of 17 individual organs
