“…In a review by Liszewski et al ., it has been inferred that high-quality MRI of the airways is an increasingly feasible alternative to conventional radiography, fluoroscopy, and CT in the evaluation of many diseases of the pediatric large airways. [ 11 ] Advances in technology have produced higher-resolution images (voxel size less 1 mm) that are less susceptible to motion artifact and allow image acquisition during free breathing, reducing the need for sedation. [ 12 13 ] These new sequences allow robust airway visualization up to the fourth bronchial generation.…”

Pediatric inflammatory myofibroblastic tumor of the trachea: Imaging spectrum and review of literature

Inflammatory myofibroblastic tumor of the airway is a very uncommon benign primary neoplasm in pediatric age group with increased local recurrence rate and potential metastatic spread. We describe a case of a 6-year boy who was brought to the pediatric emergency with severe respiratory distress, dry cough, and stridor. Contrast-enhanced computed tomography and magnetic resonance imaging (MRI) of the neck showed a polypoidal mass lesion in the right anterolateral trachea causing significant airway narrowing. Bronchoscopic findings correlated with the imaging. The lesion was confirmed at surgery and was completely removed by surgical excision. Histopathology revealed an inflammatory myofibroblastic tumor. MRI findings of this entity in a child have not been reported before.

“…Both 2-D and 3-D cine MRI can be performed. Cine MRI has been used to assess tracheobronchomalacia in pediatric patients, showing similar results to bronchoscopy and CT [ 6 , 18 , 55 , 56 ]. A recent study has described another possibility of a free-breathing fast T2-W MultiVane MRI sequence (Philips Healthcare, Best, The Netherlands), which is reported as a technically feasible and promising new MRI technique for evaluating pediatric large airways [ 57 ].…”

Imaging speed, spatial resolution and availability have made CT the favored cross-sectional imaging modality for evaluating various respiratory diseases of children — but only for the price of a radiation exposure. MRI is increasingly being appreciated as an alternative to CT, not only for offering three-dimensional (3-D) imaging without radiation exposure at only slightly inferior spatial resolution, but also for its superior soft-tissue contrast and exclusive morpho-functional imaging capacities beyond the scope of CT. Continuing technical improvements and experience with this so far under-utilized modality contribute to a growing acceptance of MRI for an increasing number of indications, in particular for pediatric patients. This review article provides the reader with practical easy-to-use protocols for common clinical indications in children. This is intended to encourage pediatric radiologists to appreciate the new horizons for applications of this rapidly evolving technique in the field of pediatric respiratory diseases.

Magnetic resonance imaging (MRI) of the lungs is one of the most underutilized imaging modality when it comes to imaging of thoracic diseases in children. This is largely due to less-than-optimal image quality and multiple technical challenges involved with MRI of the lungs. Advances in MRI technology along with increased awareness about optimization of MR protocol have led to it being viewed as a feasible option for evaluation of various chest diseases in children. This short review article takes the reader to the road less travelled to explore newer horizons for applications of this rapidly evolving magnetic resonance technique in the field of thoracic diseases in children.
