Lungs in infants and young children: improved thin-section CT with a noninvasive controlled-ventilation technique--initial experience.
Three sedated young children underwent thin-section computed tomography (CT) of the chest while breathing and during controlled respiratory pauses induced by means of a step increase in positive-pressure ventilation applied via a face mask. Motion-free inspiratory and expiratory thin-section CT images were successfully acquired during 8-12-second respiratory pauses. This simple, reproducible technique produced thin-section CT images that were clearer and more clinically useful than those obtained during quiet tidal breathing.
