Predictors for Bronchoalveolar Lavage (BAL) Recovery Rate Derived From Quantified Computed Tomography (qCT)
January 2, 2018 updated by: Dr. Frederik Trinkmann, Universitätsmedizin Mannheim
Predictors for Bronchoalveolar Lavage Recovery Rate Derived From Quantified Computed Tomography
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.
