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 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.

Dgemric index

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 We found that the dGEMRIC index decreased to a substantially higher degree in operatively treated patients with FAI compared with nonoperative management at 1-year followup. The baseline dGEMRIC index correlated with the improvement in the WOMAC score 1 year postoperatively. 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.

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.

A recent study indicated that low dGEMRIC may predict future radiographic knee OA.43 The dGEMRIC index has been shown to be low in individuals with moderate to severe radiographic knee OA,15 after cruciate ligament injury44 45 and in diseased knee compartments on arthroscopy.46 In addition, a range of dGEMRIC values has been observed in radiographically comparable compartments demonstrating The dGEMRIC index (mean ± sd) at four times (min ± sd) after intravenous injection of double dose Magnevist. 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.

Interpretation — A traumatic cartilage injury is associated with a high prevalence of OA after 17 years.

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. We found that the dGEMRIC index decreased to a substantially higher degree in operatively treated patients with FAI compared with nonoperative management at 1-year followup.

Quantitative MRI (qMRI) assessment of cartilage morphology has been validated in joints with thin cartilage plates (6) but has not been used to describe local acetabular and femoral cartilage morphology. 10 List of Papers I Tiderius C J, Tjörnstrand J, Akeson P, Sodersten K, Dahlberg L, Leander P. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC): intra- and interobserver va Current students New students International Desk Academic matters & support IT services & support Careers Service 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 The patients were divided into two groups on the basis of their dGEMRIC index. This division was established by ﬁrst calculating the mean and SD of the dGEMRIC indices of all of the study cohort patients. Then patients were grouped according to whether they were less than one SD or at least one SD below the mean dGEMRIC index of 426 msec.
