When the technique is adapted and applied to menisci it is called dGEMRIM. At a time point after an intravenous or intra-articular negatively charged gadolinium agent is injected that allows diffusion of the material to the cartilage, the technique enhances areas of high 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 with preradiographic degenerative cartilage changes.

Dgemric technique

In the last decade, cartilage imaging with dGEMRIC has been established as an accurate and reliable tool for assessment of cartilage status in the knee and hip joint. DOI: 10.1002/jmri.21869 Corpus ID: 1030069. High resolution fast T1 mapping technique for dGEMRIC @article{Sur2009HighRF, title={High resolution fast T1 mapping technique for dGEMRIC}, author={S. Sur and T. Mamisch and Timothy Hughes and Y. Kim}, journal={Journal of Magnetic Resonance Imaging}, year={2009}, volume={30} } Third, dGEMRIC is a rather complex MRI technique that can be influenced by the patient’s body mass index, the degree of physical activity, and variations in delay between injection of contrast agent and imaging [52, 53]. Noninvasive techniques are needed for the assessment of the repair tissue. HYPOTHESIS: Magnetic resonance imaging (MRI) with delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) can give valuable information regarding the quality and quantity of the repaired cartilage lesion. STUDY DESIGN: Cohort study; Level of evidence, 3.

Outcomes of dGEMRIC, however, did not change after Viscosupplementation, indicating no change in cartilage p-values adjusted using Holm's method <0.05 .

The 3D Look-Locker technique has been validated against the traditional inversion recovery technique. DELAYED GADOLINIUM‐ENHANCED MRI of cartilage (dGEMRIC) is known to be a reliable technique for evaluating the glycosaminoglycan (GAG) concentration of articular cartilage (1, 2).

Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the development of …

M. Durkan1, J. Szumowski2, D. Brown1, D. Crawford1, (DGEMRIC) is a well-established procedure with a potential to quantitatively measure the fixed-charge density (FCD) of proteoglycan aggregates [1]. The dGEMRIC technique is used to depict cartilage quality in vivo. The aim of this study was to investigate the potential of combining the benefits of MRA with biochemically sensitive imaging.

Techniques used to assess proteoglycan content and distribution include sodium-23 imaging, delayed gadolinium-enhanced MR imaging of cartilage (dGEMRIC), and T1rho (>)-weighted MR imaging. An alternative imaging modality, Delayed Gadolinium-Enhanced MRI of Cartilage (dGEMRIC), uses MRI to measure the relaxation of hydrogen atoms in cartilage bathed in a paramagnetic gadolinium contrast agent, for example, gadobenate dimeglumine (MultiHance ®, Bracco, USA).

The dGEMRIC technique can be easily implemented clinically by using a standard 1.5 or 3.0 T magnet. Although the duration of the total acquisition time (up to 2 hours) diminishes its attractiveness for clinical use, dGEMRIC has potential value in clinical trials, where it has shown the ability to demonstrate changes in morphologically intact cartilage that may be predictive of progression to

Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. Background: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a validated technique for evaluating cartilage health in developmental dysplasia of the hip (DDH), which can be a helpful prognosticator for the response to surgical treatments. dGEMRIC requires intravenous injection of gadolinium contrast, however, which adds time, expense, and possible adverse reactions to the imaging procedure. The dGEMRIC technique is based on the electrical polarity of gadolinium [Gd (DPTA)2− ions] and glycosaminoglycans in the joint. SCIENTIFIC ARTICLE Using the dGEMRIC technique to evaluate cartilage health in the presence of surgical hardware at 3T: comparison of inversion recovery and saturation recovery approaches The non-invasive MR imaging technique called delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) can be used to assess the concentration of glycosaminoglycans (GAGs) in the extracellular cartilage matrix5.

120 p. Research output: Thesis › Doctoral Thesis (compilation) (dGEMRIC) has been shown to be a clinically useful tool for assessing the glycosaminoglycan (GAG) content in cartilage (1–4). Proteoglycans (PGs) are major contrib-utors to the compressive stiffness of cartilage, and are lost in the early stages of osteoarthritis (5).

However, because of the location of the hip joint deep within the body and due to the fairly thin cartilage layers that require high spatial resolution, the diagnosis of early hip joint cartilage alterations may be problematic.
