Interventions

Group 1: Retrospective inclusion of patients who underwent lung scintigraphy in SPECT/low-dose-CT for clinical reasons. Calculation of lobe-based pulmonary function: 1. planar scintigraphy

clinical Standard 2. manually from SPECT/low-dose-CT 3. semi-automatic using specific Software (3 Reader

blinded to each other and to clinical Information)

Design outcomes

Primary

Measure	Time frame
data from planar scintigraphy and SPECT/low-dose-CT (both, the manual and the semi-automatic approach) differ significantly	—

Secondary

Measure	Time frame
1. There is no difference between manual and semi-automatic evaluation of SPECT/low-dose-CT. 2. Results from semi-automatic quantification are investigator independent	—
