Patient-reported outcome tools used included the modified Harris hip score (mHHS), the Nonarthritic Hip Score (NAHS), the Hip Outcome Score Activities of Daily Living (HOS-ADL), and the Hip Outcome Score Sport-Specific Subscale (HOS-SSS) as well as a visual analog scale (VAS) for pain and a patient satisfaction score. The dGEMRIC index was 20–30 % lower in the patients with early OA compared to healthy volunteers (P < 0.003) at all time points, with largest difference at the earlier time points due to faster wash-in of the contrast in the OA cartilage. The baseline dGEMRIC index correlated with the improvement in the WOMAC score 1 year postoperatively. The dGEMRIC index was able to depict early chondral degenerations in the posterosuperior quadrant. differences in the dGEMRIC index across a region were used to predict difference in stiffness.

In these knees, the mean baseline dGEMRIC index was lower than that in the knees without radiographic OA (mean ± SD 312 ± 64 msec and 383 ± 60 msec, respectively; P = 0.03) (Figure 1). 2012-01-01 2012-07-01 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.

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). T(1Gd) (T(1) after penetration of a 0.2 mmol/kg dose of Gd-DTPA(2-)) has been used as the dGEMRIC index, although (1/T(1Gd)-1/T(1o)) should be more representative of Gd-DTPA(2-) concentration (where T(1o) = T(1) before contrast). 2006-11-01 The dGEMRIC index was assessed on MRI according to established protocol. Regression analysis adjusted for age, sex, body mass index (BMI), and presence of clinical knee OA. Mean age and BMI were Delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) is based on the theory that Gd‐DTPA2− will distribute in inverse relation to cartilage glycosaminoglycan (GAG).

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 The dGEMRIC index is highly correlated to mechanical stiffness. 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.

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. dGEMRIC index in the medial weight-bearing cartilage. Conclusions: The higher pre-contrast T 1 in the superficial region than in the deep region is an indication of a higher water content in superficial cartilage. The uptake of contrast was found to be from the superficial region of 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.

CONCLUSION: The results of the present study support the dGEMRIC index as a clinically relevant measure of cartilage integrity and suggest that a low index may be predictive of the development of knee OA. using T1(Gd) as the dGEMRIC Index as a measure of Gd-DTPA2-distribution may be less suitable at 3T than 1.5T.

1) [ 59 ]. Similar to the knee [ 4, 34 ], dGEMRIC is a promising tool to quantify cartilage healing or degeneration before and after joint-preserving hip surgery and to monitor the natural course of hip diseases. 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.
