The impact of reconstruction techniques on observer performance for the detection and characterization of small pulmonary nodules in chest CT of children under 13 years

Highlights: • Maximum intensity projections improve detection of pulmonary nodules in children. • Double reading is a powerful tool in chest CTs of children with a malignancy. • Pulmonary nodule characterization benefits from 1 mm scans in three planes. • Intrapulmonary lymph nodes occur in children with and without malignancy. • Pulmonary nodules in children with cancer do not necessarily represent metastases. - Abstract: ObjectiveTo compare three different reconstruction techniques of CT data for the detection of pulmonary nodules in children under 13 years. Secondly to assess the prevalence of perifissural nodular opacities.
