Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is an imaging technique that can identify pre-radiographic degenerative changes in articular cartilage, and potentially also in the meniscus [ 12, 13 ]. When this technique is applied to the latter tissue, it is designated gadolinium enhanced MRI of meniscus (dGEMRIM). Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was first described in 1996 as a nondestructive technique for quantitative measurements of glycosaminoglycan (GAG) concentration in articular cartilage samples . The dGEMRIC (delayed gadolinium enhanced magnetic resonance imaging [MRI] of cartilage) technique has previously been used in the knee and hip as a non-invasive method to evaluate one aspect of cartilage biochemical status, that of the spatial distribution of cartilage glycosaminoglycan (GAG) concentration 6 On the morphologic MRI scan, there is labral chondral degeneration.
