Central airways assessment is routinely performed with bronchoscopy, which requires sedation and does not allow exact airway measurements. Although cine-CT is used as a non-invasive alternative, its use is limited by radiation. MRI, as a radiation-free technique, is an attractive alternative for CT. We aim to give a comprehensive overview of MRI capabilities to assess central airways disease in pediatric and adult patients in order to assist radiologists in “imaging central airways gently and wisely”.

We will describe and illustrate a practical approach to assess pediatric and adult central airways disease with MRI as follow: 1) central airways mechanics from a radiology perspective; 2) bronchoscopy, CT and MRI of central airways: techniques and pros/cons; 2) 2D vs. 3D MRI; 3) static vs. dynamic MRI; 4) spirometry-guided dynamic MRI; 5) contrast enhanced MRI of the central airways and 6) post-processing techniques: clinical and advanced settings. Finally, we will provide and illustrate diagnostic algorithms, protocols and clinical scenarios that will facilitate radiologists to "wisely" select MRI over CT for studying central airway dimensions and dynamics.
