The dGEMRIC technique can be easily implemented clinically by using a standard 1.5 or 3.0 T magnet. Although the duration of the total acquisition time (up to 2 hours) diminishes its attractiveness for clinical use, dGEMRIC has potential value in clinical trials, where it has shown the ability to demonstrate changes in morphologically intact cartilage that may be predictive of progression to

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. These preliminary results suggest that the dGEMRIC technique may be able to detect change in proteoglycan content in knee cartilage among individuals taking collagen hydrolysate after 24 weeks. 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. The dGEMRIC technique is based on the electrical polarity of gadolinium [Gd (DPTA)2− ions] and glycosaminoglycans in the joint.

To determine the feasibility of using a high resolution isotropic three‐dimensional (3D) fast T1 mapping sequence for delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) to assess osteoarthritis in
GAGs have side groups that confer a negative charge to the cartilage matrix. 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. Compositional assessment techniques include T2 mapping, delayed gadolinium-enhanced MR imaging of cartilage (dGEMRIC), T1ρ imaging, sodium imaging, and diffusion-weighted imaging.

2011-06-29 Will be measured using the delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) technique Lumbar lordosis angle [ Time Frame: Baseline: before surgery ] Will be measured by the EOS imaging system. 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 aim of this study was to investigate the potential of combining the benefits of MRA with biochemically sensitive imaging. Therefore, a comparison of ia versus iv contrast agent administration for dGEMRIC in the assessment of hip joint cartilage was performed.
In acetabular dysplasia, there is increased mechanical load due to the shallow acetabulum, which will normalize after pelvic osteotomy. 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. 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.

Methods. In 20 early-stage knee OA patients (KLG I-II), 3D dGEMRIC at 3T was acquired before and 14 weeks after 3 Outcomes of dGEMRIC, however, did not change after Viscosupplementation, indicating no change in cartilage p-values adjusted using Holm's method <0.05 .

Technical issues regarding optimization of the dGEMRIC technique for human clinical application have been investigated and reviewed [8, 9]. 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.
We hypothesize that the early diagnosis of degenerative changes in the temporomandibular joint could be diagnosed using dGEMRIC technique.
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.

SCIENTIFIC ARTICLE Using the dGEMRIC technique to evaluate cartilage health in the presence of surgical hardware at 3T: comparison of inversion recovery and saturation recovery approaches The non-invasive MR imaging technique called delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) can be used to assess the concentration of glycosaminoglycans (GAGs) in the extracellular cartilage matrix5.
