Detailed Description

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

Prospective non-interventional, monocentric observational study on imbalances in regional lung ventilation compared to chest CT in post-acute-Covid-19. The aim is to verify the agreement between computerized tomography derived imaging variables and electrical impedance tomography in detecting lung ventilation imbalances. The primary study objective is to match CT morphological changes in regional ventilation in post-acute-COVID-19 patients and/or changes in lung function examination, with changes that can be visualized by electroimpedance tomography.
