19 Aug 2015 Our study aimed to determine whether dGEMRIC indices are predictive of Twelve of the sixty-four hips had a dGEMRIC index of <323 msec 

The dGEMRIC index was calculated as the average of the T1 values for the acetabular and femoral head cartilages. Results: The dGEMRIC index correlated with both pain (rs = -0.50, p < 0.0001) and the lateral center-edge angle (rs = 0.52, p < 0.0001), whereas the joint space width did not correlate with either, with the numbers available.

A generalized relationship was found to provide good correspondence across sources and regions. Use of the dGEMRIC index as a predictive measure of stiffness is possible, depending on the application's acceptable error. Copyright (c) 2007 Orthopaedic Research Society. PMID: 17427215 2006-11-01 · The mean T1 (Gd) within a clinically relevant region of articular cartilage is usually referred to as the dGEMRIC Index 6. In the current dGEMRIC protocol, Gd-DTPA 2− is administered per kilogram body weight with the assumption that the distribution volume of the contrast agent is proportional to body weight.

Alternatively, further dGEMRIC studies could be performed at 1.5T, or at 3T with higher doses of Gd-DTPA2-and/or concurrent measurement of T1o.

The technique assumes that the plasma levels of the contrast agent Gd-DTPA2− are the same across individuals after intravenous (IV) injection, when dosing by weight. However, adipose tissue has lower extracellular water (ECW) than lean tissue. The aims of this study were to measure In Study III, those who increased their physical activity showed a significant increase in dGEMRIC index in both superficial and deep layers in lateral weight-bearing cartilage. Those who decreased their physical activity showed a significant decrease in dGEMRIC index in the medial weight-bearing cartilage.

The implication of biomechanics in alterations in molecular metrics is further strengthened by the observation that knee malalignment has been shown to correlate to medial/lateral ratios of the dGEMRIC Index . The dGEMRIC index in the group below 50° (no FAI) was higher than in the group with an alpha angle above 65° (consistent with FAI, P = 0.026). Furthermore, the total dGEMRIC index in SCFE hips correlated inversely to the alpha angle (P = 0.046, R = −0.40) . For this correlation, one randomly selected hip was used in the two bilateral cases. 2018-06-02 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 Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is based on the theory that Gd-DTPA(2-) will distribute in inverse relation to cartilage glycosaminoglycan (GAG).

In the posterosuperior quadrant, the dGEMRIC index was higher for patients with intact carti-lage compared with hips with chondral lesions A low dGEMRIC index has been associated with failure of the Bernese periacetabular osteot-omy in adult patients with DDH12, presumably because it can differentiate the cases where the OA disease process has advanced too far from those where the cartilage composition is relatively normal.

Gray1,2,6 1New England Baptist Bone and Joint Institute, Boston, Massachusetts 2Harvard-MIT Division of Health Sciences and Technology ObjectiveHigh tibial osteotomy (HTO) and knee joint distraction (KJD) are treatments to unload the osteoarthritic (OA) joint with proven success in postponing a total knee arthroplasty (TKA). While We measured dGEMRIC index, cartilage thickness, surface area, and volume for each of the four joint quadrants and compared the manual and the automated 3-D analyses using mean differences. Agreement between the techniques was assessed using intraclass correlation coefficients (ICC). 2021-03-19 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 as good as a direct mechanical measurement, the index can be used as a predictive measure of stiffness.

Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) reflects cartilage glycosaminoglycan (GAG) distribution. The technique assumes that the plasma levels of the contrast agent Gd-DTPA2− are the same across individuals after intravenous (IV) injection, when dosing by weight. However, adipose tissue has lower extracellular water (ECW) than lean tissue. The aims of this study were to measure

The uptake of contrast was found to be from the superficial region of In the posterosuperior quadrant, the dGEMRIC index was higher for patients with intact cartilage compared with hips with chondral lesions (592 ± 203 ms versus 444 ± 205 ms, p < 0.001). CONCLUSIONS We found a decline in acetabular, femoral, and regional dGEMRIC indices for the surgically treated group at 1-year followup despite an improvement in all PROMs. The dGEMRIC index was calculated as the average of the T1 values for the acetabular and femoral head cartilages. Results: The dGEMRIC index correlated with both pain (rs = -0.50, p < 0.0001) and the lateral center-edge angle (rs = 0.52, p < 0.0001), whereas the joint space width did not correlate with either, with the numbers available.

2021-03-19 2012-01-01 Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) reflects cartilage glycosaminoglycan (GAG) distribution. The technique assumes that the plasma levels of the contrast agent Gd-DTPA2− are the same across individuals after intravenous (IV) injection, when dosing by weight. However, adipose tissue has lower extracellular water (ECW) than lean tissue. A negative
correlation between the dGEMRIC index in the adjacent cartilage and future OA suggests that the quality of the
surrounding cartilage influences outcome after cartilage repair surgery.
