Paediatric neuroimaging.

An increasing number of advanced magnetic resonance (MR) techniques are routinely performed in paediatric neuroradiology departments. The most diffuse technique, standard diffusion weighted imaging, is very fast and is becoming increasingly common in routine practice. The usefulness of calculating apparent diffusion coefficient (ADC) is also well known and frequently used, together with voxel proton spectroscopy. Others techniques such as perfusion or BOLD still have a limited use. The most frequent applications of these techniques are discussed in some of the most representative fields of paediatric neuroradiology.
