29 patients with ACL rupture were investigated with dGEMRIC 3 weeks and 2 years after injury. dGEMRIC index was lower compared to non-injured controls. 2007-04-12 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.

For example, adherence to an exercise regimen was shown to increase the dGEMRIC Index [48, 59, 60]. Similarly, in obese subjects, quadriceps strength was shown to correlate positively with dGEMRIC , as did weight loss . using T1(Gd) as the dGEMRIC Index as a measure of Gd-DTPA2-distribution may be less suitable at 3T than 1.5T. However, T1(Gd) as an index may prove to be clinically useful. 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. T1o T1(Gd) T1, ms 300 500 700 900 1100 1300 2018-04-01 · The dGEMRIC index was calculated as the mean T 1Gd of all voxels in each of the nine ROIs. An intraobserver analysis for T1 analysis was made in 10 randomly selected SCFE hips.
The dGEMRIC indices, with and without BMI dose correction, for each of the 4 ROI and averaged for each sagittal section are presented in Table 2.There was statistically significant negative correlation between age and dGEMRIC index regardless of BMI dose correction (medial dGEMRIC index, r = −0.40, p < 0.001; lateral dGEMRIC index, r = −0.29, p = 0.012). dGEMRIC index with quantitative measures of proteoglycan content and with semi-quantitative histologic scores3.

The baseline dGEMRIC index correlated with the improvement in the WOMAC score 1 year postoperatively. differences in the dGEMRIC index across a region were used to predict difference in stiffness.

(3) Is there a correlation between the baseline dGEMRIC index and the change of patient-reported outcome measures (PROMs) at 1-year followup? The dGEMRIC index was calculated as the average of the T1 values for the acetabular and femoral head cartilages.
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. 29 patients with ACL rupture were investigated with dGEMRIC 3 weeks and 2 years after injury. dGEMRIC index was lower compared to non-injured controls. 2007-04-12
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 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.

The following inclusion criteria were used: the presence of hip pain; radiographic signs of skeletal maturity; AP radiographs; and the availability of both CT and MRI with dGEMRIC of the same hip joint. 2019-06-13 The dGEMRIC index in the cartilage adjacent to the repair tissue correlated negatively with radiographic osteophyte score, r = –0.75 (p = 0.03). Interpretation — A traumatic cartilage injury is associated with a high prevalence of OA after 17 years. 2020-06-30 Patients with a dGEMRIC index of ≥323 msec (less than one SD below the cohort mean) demonstrated significantly greater improvement in patient-reported outcome scores and the VAS for pain after hip arthroscopy. Level of Evidence: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence. clinical studies, the dGEMRIC Index of articular cartilage, reported as T1(Gd) (T1 after penetration of Gd-DTPA2-), has been shown to correlate with a number of physiologic and clinical findings (1). 2018-05-09 OBJECTIVE: To examine the predictive value of the delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) index with regard to future radiographic osteoarthritis (OA).

The CAL index 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 Preoperative delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) for patients undergoing hip arthroscopy: indices are predictive 10 Nov 2016 (3) Is there a correlation between the baseline dGEMRIC index and the change of dGEMRIC indices of femoral and acetabular cartilage were dGEMRIC (delayed Gadolinium Enhanced MRI of Cartilage) is a technique for T1(Gd), has been used as the dGEMRIC Index in a number of studies to Background: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification of biochemical dGEMRIC. At 33–44 test locations for each tibial plateau, the load response to focal indentation was measured as an index of cartilage stiffness.
RESULTS: The mean dGEMRIC index (and standard deviation) for this cohort (473 +/- 104 msec) was significantly lower than that of a morphologically normal hip (570 +/- 90 msec). The anterior center-edge angle, the joint space width, and the presence of a labral tear were all found to be associated with osteoarthritis in the univariate analysis. ized, longitudinal study51 that compared the dGEMRIC index of patients with FAI undergoing surgery with those treated nonoperatively. The following inclusion criteria were used: the presence of hip pain; radiographic signs of skeletal maturity; AP radiographs; and the availability of both CT and MRI with dGEMRIC of the same hip joint. Similarly, in obese subjects, quadriceps strength was shown to correlate positively with dGEMRIC , as did weight loss . 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 .
