3D computed tomography airway geometry for predicting bronchoscopic accessibility in peripheral pulmonary nodules: a prospective study

Bronchoscopic diagnosis of peripheral pulmonary nodules (PPNs) using radial probe endobronchial ultrasound (rEBUS) has been widely studied. However, the prospective utility of computed tomography (CT)-derived airway geometrical analysis for predicting rEBUS accessibility remains underexplored. This study aimed to determine whether quantitative CT airway geometric characteristics can improve preprocedural planning by predicting the bronchoscopic accessibility of PPNs.
