Computed tomography evaluation of pediatric pulmonary hypertension

Although rare in the pediatric population, pulmonary hypertension is a significant cause of morbidity and mortality in affected individuals. In addition to evaluating potential causes and severity of parenchymal lung diseases, non-contrast high-resolution CT of the chest can aid in the diagnosis of heritable and acquired causes. In addition to evaluating parenchymal lung disease, CT angiography can help to confirm findings of pulmonary hypertension using criteria similar to echocardiography, and provide detailed assessment of the pulmonary vascularity in specific causes.
