Jul 01, 2013 · The dGEMRIC MRI protocol is a useful method to evaluate cartilage repair. In addition, local cartilage repair influenced the cartilage quality at other location in the joint. These findings validate the use of dGEMRIC for non-invasive evaluation of the effects of cartilage regeneration. The delayed gadolinium enhanced MRI of cartilage (dGEMRIC) method is a validated imaging technique for estimation of the GAG content, based on the principle that the intravenously injected contrast agent Gd(DTPA)2-(Magnevist®, Bayer Schering Pharma) distributes in the cartilage in an inverse relationship to the GAG content (1). Delayed Gadolinium-enhanced MRI Of Cartilage + 1 variant.

These findings validate the use of dGEMRIC for noninvasive evaluation of the effects of cartilage regeneration. Keywords: dGEMRIC Delayed contrast-enhanced MRI of cartilage (dGEMRIC) is a noninvasive technique to study cartilage glycosaminoglycan (GAG) content in vivo. This study evaluates dGEMRIC in patients with preradiographic degenerative cartilage changes. dGEMRIC, or delayed gadolinium-enhanced MRI of cartilageis a technique that can be used quantitatively to assess glycosaminoglycan content of cartilage or qualitatively to asses the overall structures of cartilage. When the technique is adapted and applied to menisciit is called 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. Delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) facilitates non-invasive evaluation of the glycosaminoglycan content in articular cartilage. The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment. The delayed gadolinium enhanced MRI of cartilage (dGEMRIC) method is a validated imaging technique for estimation of the GAG content, based on the principle that the intravenously injected contrast agent Gd(DTPA)2-(Magnevist®, Bayer Schering Pharma) distributes in the cartilage in an inverse relationship to the GAG content (1). It has been shown that delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) is a valid, reliable and non-invasive contrast-enhanced MRI technique that can be used to estimate the relative GAG content in articular cartilage in a clinical setting 24.
