Assessment of lung function in children by cross-sectional imaging: techniques and clinical applications

Imaging techniques are indispensable for diagnosis and follow-up of paediatric pulmonary diseases. In the past, interest was focused on morphological aspects of pulmonary tissue. With the development of novel CT and MRI techniques, functional pulmonary imaging became available. In this review, the new techniques of cross-sectional functional imaging of the lung are presented and the value of these methods for investigating paediatric pulmonary diseases and their potential clinical applications are discussed.
