Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- Spirometry (basic examination within the scope of pulmonary function diagnostics) – if pulmonary function limitation is suspected.
- X-ray of the thorax (X-ray thorax/chest), in two planes – for orienting imaging of the heart and lungs.
- Computed tomography of the thorax / chest (thoracic CT) – to exclude tumors.
