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

We show that the analysis of one central slice over the hip joint (slice 2) provides similar information as the average dGEMRIC index … 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). The overlap between 3-D cartilage volumes was assessed Cartilage Quality (dGEMRIC Index) Following Knee Joint Distraction or High Tibial Osteotomy DSpace/Manakin Repository Besselink, Nick J; Vincken, Koen L; Bartels, L Wilbert; van Heerwaarden, Ronald J; Concepcion, Arno N; Marijnissen, Anne C A; Spruijt, Sander; Custers, Roel J H; van der Woude, Jan-Ton A D; Wiegant, Karen; Welsing, Paco M J; Mastbergen, Simon C; Lafeber, Floris P J G Delayed gadolinium-enhanced magnetic resonance imaging of cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the spin-lattice relaxation time or T1 relaxation time. Current research is investigating the clinical application of dGEMRIC as a quantitative tool for monitoring cartilage function in diseased or repair cartilage. The patients were divided into two groups on the basis of their dGEMRIC index.

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.

differences in the dGEMRIC index across a region were used to predict difference in stiffness.

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.

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.

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.

Acetabular dGEMRIC indices were measured on the 7 clock positions of the superior circumference (9 to 3 o’clock). 51 Femoral dGEMRIC indices were measured on the concordant 7 clock positions. The anatomic landmark for the acetabular 6 o’clock position was the acetabular teardrop.

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.

Six years later, 9 of the 16 knees showed radiographic OA changes. 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).

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.
