Osteoarthritis (OA) is an articular disease that reflects a complex interplay of biochemical, biomechanical, metabolic and genetic factors, which are often triggered by injury, and mediated by inflammation, catabolic cytokines and enzymes. Articular cartilage is a non calcified tissue well identified on MRI, helpful to define normal cartilage and to quantify cartilage abnormalities according to semi-quantitative scoring methods. We presented articular lesions related to cartilage loss in knees and hips. We discussed the interest of conventional MRI and non-invasive quantitative magnetic resonance imaging (qMRI) (volumetric and cartilage thickness measurement, T2 mapping, dGEMRIC, T1r mapping) techniques to assess biochemical and mechanical cartilage abnormalities and to establish their association with morphological cartilage lesions and/or to predict them. We concluded by other promising imaging technics able to be used in the future to depict cartilage abnormalities.
