Brief Summary

Bronchoalveolar lavage (BAL) is an important diagnostic method. The percentage of fluid extracted after instillation (recovery rate) is crucial for following diagnostic tests. The investigators aimed to compare novel quantified airway parameters from pre-interventional lung computed tomography (CT) with recovery rates to find possible predictive markers.
