Methods One hundred and forty-eight women (one knee for each subject) aged ≥40 years were included

What does DGEMRIC stand for? List of 7 DGEMRIC definitions. Top DGEMRIC abbreviation meanings updated February 2021 dGEMRIC, like most biochemical methods for measuring cartilage GAG including radiotracer, histology with cationic dyes, and biochemical assays, is based on biophysical principles elucidated by Maroudas almost 40 years ago . These principles rely on the fact that GAG is the source of the majority of the fixed charge on the cartilage Traditionally dGEMRIC has been performed using a two-dimensional T1-weighted inversion recovery (2D-IR) sequence to acquire data for quantitative T1 mapping [18, 19].The major advantage of this method is the widespread availability of the sequence and desirable contrast properties (cartilage versus fluid). For dGEMRIC, the optimum time window after contrast‐injection (gadopentetate dimeglumine) was defined as the plateau of the T 1 curve of repeated measurements 15–90 minutes postinjection and assessed in all volunteers. Reference values of healthy‐appearing cartilage from all individuals and values in areas of chondromalacia were assessed The dGEMRIC index and indentation stiffness were highly correlated within regions, within cartilage from the same joint, and across cartilage from all the joints, so long as the dGEMRIC index from with dGEMRIC for the detection of cartilage damage? Do the mean acetabular and femoral dGEMRIC indices differ between (2) superior acetabular clock positions with and without impingement and (3)between cam andpincer FAI? METHODS We performed a retrospective, institutional review board– approved, comparative radiological study of 21 hips in 20 Background: Even though cartilage loss is a known feature of psoriatic (PsA) and rheumatoid arthritis (RA), research is sparse on its role in the pathogenesis of PsA, its potential use for disease monitoring and for differentiation from RA. We therefore assessed the use of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) to evaluate biochemical cartilage changes in The dGEMRIC technique can be easily implemented clinically by using a standard 1.5 or 3.0 T magnet.

Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a technique to evaluate cartilage quality by estimation of glycosaminoglycan (GAG) content, a low dGEMRIC index indicates low cartilage quality. The characteristic resistance to compressive forces of healthy cartilage relies on high GAG content.

inium contrast, however, which adds time, expense, and possible adverse reactions to the imaging procedure. Newer MRI cartilage mapping techniques such as T1 rho (ρ) and T2* have been performed in the hip without the need for any contrast, although it is unknown whether they are equivalent to dGEMRIC. Question/purpose In this study, our purpose was to determine the correlation between the

A contrast medium is used, the concentration of which in the cartilage is inversely proportional to the amount of GAG. 2021-03-19 Background: Even though cartilage loss is a known feature of psoriatic (PsA) and rheumatoid arthritis (RA), research is sparse on its role in the pathogenesis of PsA, its potential use for disease monitoring and for differentiation from RA. We therefore assessed the use of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) to evaluate biochemical cartilage changes in 2016-02-11 The delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) index is highly correlated to mechanical stiffness, and, although not as good as a direct mechanical measurement, the index can be used The average dGEMRIC index ranged from 570 ms (no dysplasia), to 550 ms (mild dysplasia), to 500 ms (moderate dysplasia), to 420 ms (severe dyplasia). This study demonstrates that biochemical MRI (i.e., dGEMRIC scans) correlates better with clinical important parameters in hip dysplasia than do traditional radiographic measures of OA, thus suggesting that this is a valid metric to be used in clinical studies … 2018-04-01 Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a technique to evaluate cartilage quality by estimation of glycosaminoglycan (GAG) content, a low dGEMRIC index indicates low cartilage quality.

imaging of cartilage, abbreviated dGEMRIC, can be used to estimate the GAG content of cartilage. A contrast medium is used, the concentration of which in the cartilage is inversely proportional to the amount of GAG. The purpose of this work was to evaluate dGEMRIC as a prognostic tool for knee cartilage changes and knee OA in humans. dGEMRIC procedure [3], anionic gadolinium contrast agent (Gd-DTPA 2− ) is first injected intravenously or intraarticularly and then allowed to diffuse into the cartilage during a pre- All Acronyms, dGEMRIC (Feb. 17, 2021, 6:02 AM), available at https://www.allacronyms.com/DGEMRIC.

A contrast medium is used, the concentration of which in the cartilage is inversely proportional to the amount of GAG. The purpose of this work was to evaluate dGEMRIC as a prognostic tool for knee cartilage changes and knee OA in humans. The objective of the study are: Evaluate OA progression by evaluating cartilage morphology, cartilage glycosaminoglycan (GAG) content, and joint space changes measured by MRI (3.0T), dGEMRIC index, and radiography, respectively using age-matched control subjects to identify disease related changes.

The characteristic resistance to compressive forces of healthy cartilage relies on high GAG content. dGEMRIC indices similar to those from their matched controls and in the normal range for hip cartilage. In all but one of the eight subjects the anterior dGEMRIC index was lower than that in the posterior region.

dGEMRIC is more sensitive to early cartilage changes in osteoarthritis than are radiographic measures and might be a helpful tool for assessing cartilage quality. 2016-02-11 · The dGEMRIC readings (mean of three different measurements in the condyle) in the injured condyle in relation to the KOOS pain score values reported by the patients at the dGEMRIC examination. The best fit line shows a significant deviation, p -value = 0.039 Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification of biochemical cartilage properties. Although dGEMRIC has been used to monitor the course of cartilage degeneration after periacetabular osteotomy (PAO) for correction of hip dysplasia, such longitudinal data are currently lacking for femoroacetabular impingement (FAI).

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. 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.
