Airway segmentation in computed tomography images can be used to analyze pulmonary diseases, however manual segmentation is labor intensive and relies on expert knowledge. This manuscript details our contribution to MICCAI's 2022 Airway Tree Modelling challenge, a competition of fully automated methods for airway segmentation. We employed a previously developed deep learning architecture based on a modified EfficientDet (MEDSeg), training from scratch for binary segmentation of the airway using the provided annotations. Our method achived 90.72 Dice in internal validation, 95.52 Dice on external validation and 93.49 Dice on the final test phase, while not being specifically designed or tuned for airway segmentation. Open source code and a pip package for predictions with our model and trained weights are in https://github.com/MICLab-Unicamp/medseg.
