[Measuring perfusion and diffusion in neuroradiology].

Neuroradiology should be regarded as a discipline with a strong focus on integral diagnosis of morphology and function of the central nervous system. With perfusion magnetic resonance imaging (P-MRI) and diffusion-weighted magnetic resonance imaging (DWI) the functional micro-structural analysis of the central nervous system has been made possible. So, disease processes may be characterised on a molecular level and P-MRI as well as DWI are now integrated in clinical routine diagnosis to improve therapy planning.
