2017-09-01 · The complete dGEMRIC protocol including contrast agent statistically significant lowered T2 relaxation times in the medial posterior femoral condyle of OA patients. However, absolute differences in T2 relaxation times were small and there was no trend towards higher or lower values after one of the protocol aspects. The protocol for delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was adapted for the evaluation of transplanted osteochondral allograft cartilage. Eight patients with focal grade 4 cartilage defects of the femoral condyle were treated with single cylindrical osteochondral allografts. At 1 and … 2016-09-01 · Here, three magnetic resonance imaging (MRI) techniques, dGEMRIC (delayed Gadolinium enhanced MRI of cartilage; dG 1 =T 1,post; dG 2 =1/T 1,post-1/T 1,pre), T 1ρ,and sodium MRI, are compared in a preclinical in vivo study to evaluate the differences in their potential for cartilage characterization and to establish an examination protocol for a following clinical study.

The hypothesis of the study was that cartilage surrounding a focal cartilage lesion in the knee does not possess degenerative changes. Estimation of mechanical properties of articular cartilage with MRI - dGEMRIC, T2 and T1 imaging in different species with variable stages of maturation. Nissi MJ(1), Rieppo J, Töyräs J, Laasanen MS, Kiviranta I, Nieminen MT, Jurvelin JS. Inﬂuence of delayed gadolinium enhanced MRI of cartilage (dGEMRIC) protocol on T2-mapping: is it possible to comprehensively assess knee cartilage composition in one post-contrast MR examination at 3 Tesla? J. Verschueren yz, J. van Tiel yz, M. Reijman y, E.E. Bron zx, S. Klein zx, J.A.N. Verhaar y, The protocol for delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was adapted for the evaluation of transplanted osteochondral allograft cartilage. Also, improvement from baseline in T1gd of the ROI defining the treated cartilage defect showed a direct relationship (P < 0.007) to the improvement of the T1gd of ROI at other locations in the joint.ConclusionsThe dGEMRIC MRI protocol is a useful method to evaluate cartilage repair.

Delayed gadolinium‐enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) is used to examine the distribution of glycosaminoglycan in cartilage. This study sought to characterize dGEMRIC in the evaluation of knee osteoarthritis (OA) according to various radiographically determined disease parameters, and to examine the relationship between alignment of the knee joint and the lateral:medial dGEMRIC ratio. For a typical dGEMRIC protocol, a double or triple dose of Gd-DTPA 2-is usually administered intravenously and joint range of motion is performed for 10 min. T1-weighted images are acquired after 30 min to 3 h (usually at least a 90 min delay is preferred) and color maps can be generated based on per-pixel calculation.
