Congenital Pulmonary Airway Malformation Volume Ratio (CVR) is widely used during prenatal ultrasound to predict outcome of fetuses with bronchopulmonary malformations (BPM). Since fetal MRI is often performed in fetuses with BPM, the aim of our study is to correlate CVR measurements by MRI and US, to compare inter-observer agreement of CVR measured by area-based MRI volume, diameter-based volume and to assess whether large lesions would be prone to more variability in CVRs among observers.

Bronchopulmonary sequestration (BPS) is a rare congenital abnormality of the lower airway resulting in a mass of nonfunctional lung tissue. Our purpose is to present the prenatal and postnatal imaging findings of a spectrum of BPS cases and to correlate with pathology findings.

We present a series of BPS evaluated with prenatal imaging (US and MRI) and postnatal imaging (radiographs, US, CT, and MRI). Pathology will be reviewed.

Our series includes isolated BPS, hybrid BPS associated with cystic pulmonary airway malformation (CPAM), BPS associated with diaphragmatic hernia, and challenging cases of intradiaphragmatic, subdiaphragmatic, and mediastinal sequestrations that can mimic other masses. We also include a case of sequestration with an associated communication to the GI tract (bronchopulmonary foregut malformation) and a case of isolated BPS that spontaneously involutes over time.

BPM’s are often identified prenatally; while some have more detailed imaging and description, many are loosely called congenital pulmonary airway malformations (CPAM). A chest radiograph is usually obtained at birth, but CT imaging is often deferred until 3-6months of age in asymptomatic babies, when surgical removal is being considered. Participation in a presurgical conference has indicated that there is poor standardization of both performance and interpretation of CT for BPM’s. High quality studies are most often hampered by poor timing of imaging, poor vascular opacification and obscuration of pathology due to atelectasis. There are four key internal feature of BPM’s that help with lesion characterization, differential diagnosis and management decisions. These include: systemic arterial supply; bronchial mucoid impaction; overinflated lung and macroscopic cysts. Reliable recognition and description of these features in all cases is essential for guiding surgical decisions since some lesions can be treated conservatively, especially those with just hyperinflation and mucoid impaction. A feature that tends to be overlooked is mucoid impaction, indicative of bronchial atresia. Cystic changes and overinflated lung may be mischaracterized. Small systemic arteries can be missed. Multiplanar reconstructions and interaction with maximum intensity projections and a 3D dataset are very helpful. This poster aims to educate by providing multiple illustrative imaging examples and a standardized report template useful for radiologists, clinicians, research and registries. Read More

Tracheomalacia (TM) is a common morbidity associated with prematurity and manifests as dynamic collapse of the trachea lumen due to cyclic changes of intrathoracic pressure during breathing. Premature infants often have elevated work of breathing (WOB) related to their distal, small airway and lung abnormalities. The large airway contribution to WOB can be determined using computational fluid dynamics (CFD), which is a well-known technique to calculate the resistance and WOB in the human airway. However, previous studies are based on static airway geometry without motion. Using the novel technique of ultrashort echo time (UTE) magnetic resonance imaging (MRI), the tidal volume and airway motion can be used to create a dynamic model for use in CFD. Our aim is to calculate the estimated WOB in a dynamic trachea with neonatal TM compared with a stable, static trachea.
