-In medicine, the term magnetic resonance //imaging// refers to a set of techniques able to study morphological alterations or follow metabolic processes or both in living organisms. These techniques can be divided into image acquisition sequences (//​imaging//​) and spectroscopy. In fact, the anatomical study in normal and pathological conditions with //imaging// (MRI) can be combined with magnetic resonance spectroscopy (MRS) to quantify //in vivo// the metabolites present in organs or lesions, and to follow the levels of these metabolites during evolution of a pathology or in response to therapeutic treatments. \\ +[[aree:​nmr:​mri:​gallery:​|{{ :​aree:​nmr:​mri:​banner-mri.png |Image gallery}}]]
