For a typical dGEMRIC protocol, a double or triple dose of Gd-DTPA 2-is usually administered intravenously and joint range of motion is performed for 10 min. T1-weighted images are acquired after 30 min to 3 h (usually at least a 90 min delay is preferred) and color maps can be generated based on per-pixel calculation. Different parameters have been proposed to acquire the data based on T1-weighting such as STIR imaging, saturation recovery, fast mapping, Look-Locker and driven equilibrium NMH MRI Protocols Hip dGEMRIC (revised July 2013) Contrast dose .4ml/kg Magnevist (check with MSK attending is eGFR is >60) Magnevist is the only agent that can be used for cartilage imaging because of its -2 charge Magnevist distributes in cartilage in an inversely proportional manner to the concentration of The following general protocol is currently suggested for dGEMRIC: intravenous injection of a double dose of Gd(DTPA) 2–, followed by 10 min of exercise of the joint, and MRI of T 1 2–3 hr post‐injection for the knee or 30–90 min for the hip. Conclusions: 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.

Here, three magnetic resonance imaging (MRI) techniques, dGEMRIC (delayed Gadolinium enhanced MRI of cartilage; dG1=T1,post; dG2=1/T1,post-1/T1,pre), T1ρ,and sodium MRI, are compared in a preclinical in vivo study to evaluate the differences in their potential for cartilage characterization and to establish an examination protocol for a

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 The dGEMRIC MRI protocol is a useful method to evaluate cartilage repair.

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

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]. As an example, delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) has recently been used in the hip. 51 This technique allows an objective quantification of early biochemical cartilage damage, even in the absence of full-thickness cartilage defects; a higher dGEMRIC index represents more glycosaminoglycan (GAG) content and indicates healthier cartilage. 51 The dGEMRIC (delayed Gadolinium Enhanced MRI of Cartilage) method exploits changes in the negatively charged cartilage milieu to detect alterations in proteoglycan structure. The protocol begins with intravenous injection of a negatively-charged gadolinium chelate such as Gd(DTPA) 2−. Such chelates are normally repulsed by the electronegative GAGs, but may accumulate in cartilage if the proteoglycan structure is disrupted. Published on February 16, 2017 by Aaron Dubrow.

The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment. Background: Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) has been used in the detection of chondropathy. Our study aimed to determine whether dGEMRIC indices are predictive of two-year patient-reported outcomes and pain scores following hip arthroscopy.
