The dGEMRIC (delayed Gadolinium Enhanced MRI of Cartilage) method exploits changes in the negatively charged cartilage milieu to detect alterations in proteoglycan structure. The protocol begins with intravenous injection of a negatively-charged gadolinium chelate such as Gd(DTPA) 2−. Such chelates are normally repulsed by the electronegative GAGs, but may accumulate in cartilage if the proteoglycan structure is disrupted.

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

As an example, delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) has recently been used in the hip. 51 This technique allows an objective quantification of early biochemical cartilage damage, even in the absence of full-thickness cartilage defects; a higher dGEMRIC index represents more glycosaminoglycan (GAG) content and indicates healthier cartilage. 51

The protocol begins with intravenous injection of a negatively-charged gadolinium chelate such as Gd(DTPA) 2−. Such chelates are normally repulsed by the electronegative GAGs, but may accumulate in cartilage if the proteoglycan structure is disrupted. Published on February 16, 2017 by Aaron Dubrow.

However, few studies have implemented this method at the hip and those that have were limited to analysis of a single slice (4). Our objective was to assess the feasibility of a three-dimensional (3D) dGEMRIC protocol to assess Materials and methods Acquisition of delayed gadolinium-enhanced and conventional MRI Participants Before acquisition of the delayed gadolinium-enhanced and For this study we used delayed gadolinium-enhanced MRI conventional MR images, a double dose (0.2 mmol/kg) of data of patients included in a prospective study in which the Magnevist® (Bayer Schering Ag, Berlin, Germany) was ad- … Here, three magnetic resonance imaging (MRI) techniques, dGEMRIC (delayed Gadolinium enhanced MRI of cartilage; dG1=T1,post; dG2=1/T1,post-1/T1,pre), T1ρ,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 Raw image data collected from dGEMRIC MRI protocol at an inversion time of 1600 milliseconds (left).

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.

These findings validate the use of dGEMRIC for non-invasive evaluation of the effects of cartilage regeneration. Biochemical and histologic data have validated the technique of delayed gadolinium-enhanced MRI, in which the T(1) values of cartilage after penetration of Gd(DTPA)2-allow assessment of the glycosaminoglycan (GAG) component of articular cartilage. This work describes the factors that have been found … Protocol issues for delayed Gd(DTPA)(2-)-enhanced MRI (dGEMRIC) for clinical evaluation of articular cartilage.
