Description
Summary:The purpose of this study was to attempt to improve upon conventional coronal computed tomographic (CT) images of neonatal chest which to date have been made by reformatting thinly spaced axial images. Nine neonates were studied by direct coronal CT scans with the patients' long axis 90 degrees to the scanning table. They were studied to further define their thoracic abnormalities detected on plain film. Spiral CT and cine scan (Imatron) were utilized. Congenital lung lesions such as congenital cystic adenomatoid malformation could not be diagnosed but their anatomical location could be accurately depicted, enabling easier surgical planning. The arterial supply to bronchopulmonary sequestrations was also identifiable. Tracheobronchial abnormalities such as tracheobronchus and bronchial atresia were also identifiable. Causing of air trapping, both intrinsic such as an atretic bronchus and extrinsic such as vascular compression were readily demonstrated. With neither special devices nor paraphernalia, the described method of direct coronal CT scans were both feasible and provided significant information. This technique allows for improved assessment of the tracheobronchial tree and more accurate detection, localization, and characteristics of lesions adjacent to the diaphragm.
