Famous for outstanding soft-tissue contrast, magnetic resonance imaging (MRI) is the key diagnostic tool in modern radiology. Besides unmatched morphological information, MRI allows quantitative functional data such as perfusion maps or tracking of individual nerve fibres, purely based on non-invasive in vivo imaging. Furthermore, it also provides insight into the metabolism, quantifying e.g. total choline content and its corresponding phosphorylation status by in vivo spectroscopy. Its versatility makes MRI an invaluable tool in all medical fields, from head-to-toe, addressing e.g. morphological changes in Alzheimer's Disease, quantifying beta-cell function in diabetes, characterizing tumor status and treatment response or simply providing a morphological map for the correct interpretation of other modality data.
