The objective of the study are: Evaluate OA progression by evaluating cartilage morphology, cartilage glycosaminoglycan (GAG) content, and joint space changes measured by MRI (3.0T), dGEMRIC index, and radiography, respectively using age-matched control subjects to identify disease related changes.

Materials and methods: MRI was performed on a whole-body 7.0 T MR scanner using a dedicated circular polarization knee coil. The protocol consisted of an inversion recovery sequence for dGEMRIC, a multiecho spin-echo sequence for standard T2 mapping, a gradient-echo sequence for T2* mapping and a morphologic PD SPACE sequence.

Its translation to clinical platforms as a means of interrogating the molecular aspects of cartilage was demonstrated in 1997 with illustrative examples of apparent molecular degeneration in cartilage that was grossly The following general protocol is currently suggested for dGEMRIC: intravenous injection of a double dose of Gd (DTPA) 2–, followed by 10 min of exercise of the joint, and MRI of T1 2–3 hr post‐injection for the knee or 30–90 min for the hip. This method has reproducibility for T1 of better than 15%. title = "Protocol issues for delayed Gd (DTPA)2--enhanced MRI (dGEMRIC) for clinical evaluation of articular cartilage", abstract = "Biochemical and histologic data have validated the technique of delayed gadolinium-enhanced MRI, in which the T1 values of cartilage after penetration of Gd (DTPA)2- allow assessment of the glycosaminoglycan (GAG) component of articular cartilage.

Background Lesions in the meniscus are risk factors for developing knee osteoarthritis (OA), not least because of the role of the meniscus in the pathological progression of OA. Delayed gadolinium enhanced MRI of cartilage (dGEMRIC) has extensively been used to identify pre-radiographic cartilage changes in OA. In contrast, its counterpart with regard to examination of the meniscus, gadolinium

Magn Reson Med 2001;45(1):36-41. Tiderius dGEMRIC, or delayed gadolinium-enhanced MRI of cartilage is a technique that can be used quantitatively to assess glycosaminoglycan content of cartilage or qualitatively to asses the overall structures of cartilage.

2016-02-11 · Magnetic Resonance Imaging (MRI) T2 mapping and delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) are able to detect early degenerative changes. 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.

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.

This work describes the factors that have been found to be important for the practical implementation of the technique: 1) Exercise immediately Request PDF | Gadolinium diethylenetriaminepentaacetate enhancement kinetics in the menisci of asymptomatic subjects: A first step towards a dedicated dGEMRIC (delayed gadolinium-enhanced MRI of MRI protocol The MRI imaging was performed using a 1.5 T Siemens Avanto MRI machine (Siemens Healthcare GmbH, Erlangen, Germany). The patients were examined using a standard knee MRI protocol [13] that was developed and used at Oslo University Hospital and included T2 mapping and a dGEMRIC [14]. The patients were Delayed Gadolinium-Enhanced MRI of Cartilage (dGEMRIC) in Early Knee Osteoarthritis Carl Johan Tiderius, Lars E. Olsson, Peter Leander, Olle Ekberg, and Leif Dahlberg* Delayed contrast-enhanced MRI of cartilage (dGEMRIC) is a noninvasive technique to study cartilage glycosaminoglycan (GAG) content in vivo. This study evaluates dGEMRIC in patients Conclusion: Because dGEMRIC protocol elements resulted in only small differences in T2 relaxation times that were not consistent and lower than the SDC in the majority of regions, our results suggest that T2-mapping and dGEMRIC can be performed reliably in a single imaging session to assess cartilage biochemical composition in knee osteoarthritis (OA) at 3 T. Compositional MRI techniques have the potential to become markers of the incidence and progression of OA, especially in the earliest stages of disease and could be useful in clinical trials when testing disease-modifying OA drugs.10, 11 Before dGEMRIC can be validated as a marker, an association must be shown between worsening of the dGEMRIC index and morphological changes over time.
