Magnetic resonance imaging was a viable and non-intrusive method for diagnosing tracheomalacia in children
Abstract
Tracheomalacia is a narrowing of the tracheal lumen, which occurs when the trachea is abnormally weak and the anterior and posterior walls appose. It is a dynamic phenomenon that can affect a segment or the entire tracheal wall. A brassy or barking cough is the most common clinical characteristic. There are no established management algorithms for diagnosing tracheomalacia, and flexible bronchoscopy is frequently used. Radiological, non-invasive methods include computed tomography (CT) and magnetic resonance imaging (MRI). Based on our findings, an MRI scan should be the primary diagnostic tool for assessing tracheomalacia in children whose only symptom is a recurrent brassy or barking cough. However, a more comprehensive diagnostic approach should be used if a chronic wet cough and/or sputum suggests a chronic endobronchial infection. This should include a CT scan and flexible bronchoscopy, as an MRI scan cannot detect the high likelihood of coexisting lower respiratory tract patholog ...
