Verhagen MV, et al. - Three different reconstruction techniques of CT data for the detection of pulmonary nodules in children under 13 years were compared in this study. Furthermore, the researchers evaluated the prevalence of perifissural nodular opacities. In chest CTs of children, maximum intensity projection (MIP) improved the detection of pulmonary nodules, but overall interreader agreement was only fair. To increase diagnostic reliability in chest CTs of children with a malignancy, double reading represented a powerful tool. Nodule characterization was best with 1 mm slices. Intrapulmonary lymph nodes occurred in children with and without malignancy.
