MRI was performed at baseline and 12-month follow-up to assess cartilage thickness. 78 eligible subjects also underwent delayed gadolinium-enhanced MRI of cartilage (dGEMRIC), an estimate of proteoglycan content.

Conclusion: The dGEMRIC MRI method markedly improved delineation of hip joint cartilage compared to non-enhanced MRI. The i.a. Gd-DTPA provided the best cartilage delineation. dGEMRIC is a clinically applicable MRI method that may improve identification of early subtle cartilage damage and the accuracy of volume measurements of hip joint cartilage.

Per MRI scan several regions-of-interest (ROIs) were defined for different locations in the joint. The dGEMRIC index (T1gd) was calculated for each ROI. Repeated-measures analysis of variance (RMANOVA) analysis was used to evaluate improvement in clinical scores and MRI T1gd over time. The dGEMRIC index (T1gd) was calculated for each ROI. RMANOVA analysis was used to evaluate improvement in clinical scores and MRI T1gd over time. Also regression analysis was performed to show the influence of local repair on cartilage quality at distant locations in the knee.

dGEMRIC requires intravenous injection of gadolinium contrast, however, which adds time, expense, and possible adverse reactions to the imaging procedure. 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.

Can nondestructive MRI provide a measurement of cartilage function? The delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) index is highly correlated to mechanical stiffness, and, although not 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 patientreported outcomes and pain scores following hip arthroscopy.

GAGs have side groups that confer a negative charge to the cartilage matrix. Background: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a validated technique for evaluating cartilage health in developmental dysplasia of the hip (DDH), which can be a helpful prognosticator for the response to surgical treatments.

PMID: 27568543 [Indexed for MEDLINE] The dGEMRIC (delayed gadolinium enhanced magnetic resonance imaging [MRI] of cartilage) technique has previously been used in the knee and hip as a non-invasive method to evaluate one aspect of cartilage biochemical status, that of the spatial distribution of … Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) A dGEMRIC involves intravenous administration of negatively charged contrast agent (Gd-DTPA 2−). After injection of Gd-DTPA2, the contrast agent penetrates the cartilage through both the articular surface and the subchondral bone [ 24 ].

The dGEMRIC MRI requires an injection of a contrast agent, while the T1-rho MRI does not. If the T1-rho is shown to be as useful as the dGEMRIC method it can then be used to look at cartilage damage in the hip without having to have an injection.

depending on the study group. Results: Studies I and II: before contrast injection, T1 was higher in the superficial region than in the deep regions of the cartilage.

dGEMRIC. Delayed gadolinium-enhanced MRI of cartilage DELAYED GADOLINIUM‐ENHANCED MRI of cartilage (dGEMRIC) is known to be a reliable technique for evaluating the glycosaminoglycan (GAG) concentration of articular cartilage (1, 2). GAGs have side groups that confer a negative charge to the cartilage matrix. Delayed gadolinium‐enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) is used to examine the distribution of glycosaminoglycan in cartilage. 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. The dGEMRIC (delayed gadolinium enhanced magnetic resonance imaging [MRI] of cartilage) technique has previously been used in the knee and hip as a non-invasive method to evaluate one aspect of cartilage biochemical status, that of the spatial distribution of cartilage glycosaminoglycan (GAG) concentration 6 This article reviews the recent application of delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and discusses its use for assessing cartilage quality in the hip joint.
