Abstract. 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 [1]. Its translation to clinical platforms as a means of interrogating the molecular aspects of cartilage was demonstrated in 1997 with illustrative examples of apparent molecular degeneration in cartilage that was grossly intact morphologically [2].

dGEMRIC, or delayed gadolinium-enhanced MRI of cartilage is 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 menisci it is called dGEMRIM. At a time point after an intravenous or intra-articular negatively charged gadolinium agent is injected that allows diffusion of the material to the cartilage, the technique enhances areas of high METHOD: We examined 32 knees using delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC), 20 years after a complete ACL tear. Only subjects who had coped with the ACL injury without ACL reconstruction (ACLR), and who presented without radiographic signs of osteoarthritis (OA) at an earlier 16-year follow-up, were included in this study. Quantitative MRI analysis, in the form of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) relies on the relationship between the highly negatively charged glycosaminoglycans (GAG) and the negatively charged MRI contrast agent gadolinium, providing a measure of quality of the cartilaginous tissue, specifically with regard to GAG content. 22 In OA, the highly negatively charged GAG are lost and when intravenously injected, the MRI contrast agent gadolinium Purpose.

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.

2013-07-01 · 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.

dGEMRIC was performed at 3-T using single (0.1 mmoI/kg) and double (0.2 mmoI/kg) doses of intravenous (i.v.) Gd-DTPA 2-. Contrast-enhanced MRI of human knee cartilage Clinical applications of the novel dGEMRIC technique to study glycosaminoglycan content in articular cartilage Tiderius, Carl Johan L The dGEMRIC index (T1gd) was calculated for each ROI. RMANOVA analysis was used to evaluate improvement in clinical scores and MRI T1gd over time.

No change in IgG glycome composition. dGEMRIC MRI analysis displayed increase in proteoglycan content within the ECM. Bansal et al. Prospective (phase I) NCT03089762: OA MRI is a noninvasive imaging technique that does not involve exposure to radiation. MRI can detect abnormalities that might be obscured by bone with other imaging methods.

Regions of interest (ROls) were drawn around the posterior weight-bearing femoral knee cartilage in lateral and medial compartments. Abstract. 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 [1].

The majority of dGEMRIC studies have been in the knee and hip, although there are a number of reports of dGEMRIC applied to the finger joints [12, 50–52] and ankle . dGEMRIC protocols have also been applied in the meniscus [54–56] and intervertebral discs [57, 58]; however, the considerations of transport are much more of a concern in these thick tissues, and the interpretation of the studies is likely to be …
