Purposemeasures relative proteoglycan content of articular cartilage

Delayed gadolinium-enhanced magnetic resonance imaging of cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the spin-lattice relaxation time or T1 relaxation time.[1] Current research is investigating the clinical application of dGEMRIC as a quantitative tool for monitoring cartilage function in diseased or repair cartilage.[2]
