Neuro-imaging in children

Abstract 

The development of imaging techniques has occurred at an astounding pace over the last two decades, and neuro-imaging has been at the forefront of those changes. Computed tomography (CT) and, particularly, magnetic resonance imaging (MRI) are now indispensable tools in the management of neurological conditions in patients of all ages and MRI has allowed paediatric neuroradiology to develop as a subspecialty in its own right. MRI techniques not only allow us to obtain high-resolution images of central nervous system anatomy and pathology, but more advanced techniques such as diffusion and perfusion imaging, MRI spectroscopy and functional MRI are now providing insights into brain function as well as structure.

Although other modalities such as ultrasound and nuclear medicine are widely used in paediatrics, this article will give a brief introduction to CT and MRI, and concentrate on some selected aspects of their role in clinical paediatric neurosciences.
