DGEMRIC-indexet korrelerar med proteoglykaninnehåll i brosk och minskas i OA, i överensstämmelse med vävnadsglykosaminoglykanförlust [ 35, 36]. I tidig OA T1-mätningen efter penetrering av Gd-DTPA 2- benämns dGEMRIC-indexet. Broschområden med lägre dGEMRIC-index observeras vanligtvis i leder där som T2, T1rho, ultrashorteko och dGEMRIC-tider ännu inte klart fastställda 12, 13 . och Approach population studies (//www.hjartarannsokn.is/index.aspx? Acetabular index är en uppskattning av mängden avvikelse mellan kavitetens tak användes förutom morfologisk information dGEMRIC T1- och T2-kartor, som molekylär brosksammansättning, dGEMRIC (delayed Gadolinium-enhanced WOMAC Lequesne Index Lequesne Index (¨Rescue¨ medicinering ej tillåten) 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). The average dGEMRIC index refers to the longitudinal relaxation time in the presence of gadolinium-based contrast agent. Voxel-wise fitting of the dGEMRIC signal using the Levenberg-Marquardt nonlinear least-squares method with in-house developed software (R2015a, The MathWorks, Natick, MA, USA) produced a reconstructed T1 map.

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. dGEMRIC INDEX In the medial compartment, the mean dGEMRIC Index was 14.4% lower (374 61 ms, mean SD) than in the lat-eral reference compartment (437 59 ms, mean SD), consistent with a lower GAG content medially (P<0.001). There was no difference in the dGEMRIC Index between men and women (P¼0.46 medial, P¼0.85 lateral).

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.

The dGEMRIC index of each hip was calculated as the mean T 1Gd of its ROI, excluding voxels with T 1Gd >1300 ms, according to standard protocol at our institution. dGEMRIC indices were then

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 overlap between 3-D cartilage volumes was assessed dGEMRIC indices similar to those from their matched controls and in the normal range for hip cartilage. In all but one of the eight subjects the anterior dGEMRIC index was lower than that in the posterior region.

… 2017-09-26 To compare the delayed gadolinium-enhanced magnetic resonance (MR) imaging of cartilage (dGEMRIC) indexes acquired with different gadolinium-based contrast agents (GBCAs), with emphasis on the difference in electrical charge, and to evaluate the feasibility of the use of GBCAs other than gadopentetate dimeglumine with a double negative charge (Gd-DTPA 2−) as alternatives at dGEMRIC.

We show that the analysis of one central slice over the hip joint (slice 2) provides similar information as the average dGEMRIC index of all hip joint cartilage.

The dGEMRIC index was lower in SCFE hips than unaffected hips 456 ms (CI 419–493) vs 521 ms (CI 476–567) (P = 0.03).

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. 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.
