Chest radiography maybe useful in determining whether underlying parenchymal lung disease (eg, meconium aspiration syndrome, pneumonia, surfactant deficiency) is present. Chest radiography also assists in excluding underlying disorders, such as congenital diaphragmatic hernia.

In newborns with idiopathic persistent pulmonary hypertension of the newborn (PPHN), the lung fields appear clear, with decreased vascular markings.

The heart size is typically normal in infants with PPHN.
