Can lung MR replace lung CT?

Diseases of the respiratory system are of great importance in paediatrics. Early detection and follow-up of infectious, congenital and environmental diseases in young patients is crucial for adequate treatment and improved outcome. Here imaging techniques play an indispensable role. In the past the interest was focused on morphological aspects of pulmonary tissue. Here CT serves as the gold standard. With the development of novel CT and MRI techniques, functional pulmonary imaging became available. This field used to be the domain of nuclear medicine. In this article the techniques for cross-sectional imaging, including functional imaging of the lung are presented. The value of CT and MRI for paediatric pulmonary diseases and their potential clinical applications are compared and discussed.
