delayed gadolinium-enhanced magnetic resonance imaging of cartilage delayed gadolinium-enhanced magnetic resonance imaging of 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. current research is investigating the clinical application of dgemric as a quantitative tool for monitoring cartilage function in diseased or repair cartilage. delayed gadolinium-enhanced magnetic resonance imaging of cartilagedgemric t1 map of knee cartilagepurposemeasures relative proteoglycan content of articular cartilage
