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 [].Its translation to clinical platforms as a means of interrogating the molecular aspects of cartilage was demonstrated in 1997 with illustrative examples of apparent …

Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. However, because of the location of the hip joint deep within the body and due to the fairly thin cartilage layers that require high spatial resolution, the diagnosis of early hip joint cartilage alterations may be problematic.

2020-12-01 Since our knowledge of both the measurement properties of these imaging techniques, and the in-vivo efficacy of CH, is insufficient to design a definitive clinical trial, we performed a pilot study to determine if dGEMRIC and T2 mapping can discriminate changes in knee hyaline cartilage among participants taking a CH preparation (Fortigel ®) compared to those taking placebo. 2016-02-11 Optimization of a 3D Phase-Sensitive IR protocol for DGEMRIC technique. M. Durkan1, J. Szumowski2, D. Brown1, D. Crawford1, (DGEMRIC) is a well-established procedure with a potential to quantitatively measure the fixed-charge density (FCD) of proteoglycan aggregates [1]. The dGEMRIC technique is used to depict cartilage quality in vivo.

The dGEMRIC effect depends on the use of a charged gadolinium contrast agent. A non-ionic contrast agent will not be able differentiate between disease and normal tissue.

Delayed gadolinium-enhanced MR imaging of cartilage (dGEMRIC) technique is based upon the fact that ions distribute in cartilage following the concentration of the negatively charged GAG molecules [].Negatively charged Gd-DTPA 2-anionic molecules will be repulsed by preserved cartilage. Conversely, if Gd-DTPA 2-is present in the hyaline cartilage, concentration can be assumed to be in regions

Using this technique, the distribution of Gd-(DTPA)2−contrast agent in cartilage after intravenous injection is assessed with quantitative T1 To determine whether either of two magnetic resonance imaging approaches - delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC), or T2 mapping - can detect short-term changes in knee hyaline cartilage among individuals taking a formulation of collagen hydrolysate. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a new technique to study cartilage glycosaminoglycan (GAG) content. The negatively charged contrast agent Gd-DTPA2-, injected intravenously, distributes in the cartilage inversely to the likewise negatively charged GAG. Noninvasive techniques are needed for the assessment of the repair tissue.

Herein, we describe the dGEMRIC technique using a new positively charged contrast agent (i.e. dGEMRIC+). Specifically, we report: the synthesis and

Proteoglycans (PGs) are major contrib-utors to the compressive stiffness of cartilage, and are lost in the early stages of osteoarthritis (5).

We examined the effect of stainless-steel and titanium hardware on dGEMRIC T 1 maps. We tested two strategies to reduce metal artifact in dGEMRIC: (1) saturation recovery (SR) instead of inversion recovery (IR) and (2) applying the metal artifact reduction sequence (MARS), in a gadolinium-doped agarose gel phantom and in vivo with titanium hardware.

The most straightforward application of dGEMRIC or any molecular imaging technique is simply to demonstrate and follow “lesions” in otherwise apparently normal-appearing cartilage. Detection and monitoring of these lesions demonstrate a number of paradigm-changing concepts in the evaluation of cartilage physiology and pathophysiology.

PY - 2015. Y1 … Up to the levels of AF and NP, this is reproducible in MRI in dGEMRIC technique, but not in X-ray or standard MRI sequences. Potentially, the MRI in dGEMRIC technique can be used as a non-invasive in vivo indicator for disc degeneration in the cervical spine. Copyright © 2016 Elsevier Inc. All rights reserved.

When the technique is adapted and applied to menisci it is called dGEMRIM. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. 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.
