Pediatric Chest MR Imaging Lung and Airways

Advances in technology coupled with optimized protocols now permit evaluation of the lungs with magnetic resonance (MR) imaging in the pediatric population. Although computed tomography remains the preferred imaging modality for this purpose, MR imaging provides a radiation-free alternative that can answer many important clinical questions and provide additional data. In addition, the use of newer techniques and equipment such as MR-imaging-compatible spirometers allows for functional assessment of the pediatric airways. This article reviews the up-to-date MR imaging techniques as well as imaging findings of selected clinically important disorders that affect the lungs and airways in the pediatric population.
