Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Ventilation - perfusion SPECT is attractive for lung function assessement. Unfortunately, it is very difficult to delineate normal to abnormal areas because of physiological uptake heterogeneity.

In that context, it would be of interest to build statistical maps from registrered normal studies and propose a new methodology for normal SPECT delineation

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with normal VQ SPECT-CT will be analysed. After a image proccesing workflow including rigid registration, non rigid registration and normalization, a voxelized mean and standard deviation map will be created. Those maps will be analyzed in regards of physiology and litterature.
