“…This recommendation is based upon our recognition that the techniques used in pediatric imaging can be challenging and require experience to obtain high-quality images that lead to an accurate diagnosis. These techniques include controlling lung inflation for inspiratory and expiratory imaging (45), the use of high-pitch CT technique to minimize imaging time, thus decreasing image blurring due to motion (46), the use of pediatric sedative medication (47,48) when appropriate, and the use of ventilation support to minimize atelectasis that can obscure areas of the lung parenchyma (49). Each of these techniques appears to improve diagnostic accuracy, although our confidence in such estimates is limited by the study design and small studies with few events.…”
