Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. 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. These preliminary results suggest that the dGEMRIC technique may be able to detect change in proteoglycan content in knee cartilage among individuals taking collagen hydrolysate after 24 weeks.

We examined the effect of stainless-steel and titanium hardware on dGEMRIC T 1 maps. We tested two strategies to reduce metal artifact in dGEMRIC: (1) saturation recovery (SR) instead of inversion recovery (IR) and (2) applying the metal artifact reduction sequence (MARS), in a gadolinium-doped agarose gel phantom and in vivo with titanium hardware.

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.

Hence, the dGEMRIC technique holds promise for the development of … 2018-05-16 The delayed Gadolinium Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC) technique is a well- established method for early assessment of cartilage quality in osteoarthritis. Using this technique, the distribution of Gd-(DTPA)2−contrast agent in cartilage after intravenous injection is assessed with quantitative T1 To determine whether either of two magnetic resonance imaging approaches - delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC), or T2 mapping - can detect short-term changes in knee hyaline cartilage among individuals taking a formulation of collagen hydrolysate. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a new technique to study cartilage glycosaminoglycan (GAG) content.

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. When the technique is adapted and applied to menisci it is called dGEMRIM. 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. 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 … Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was first described in 1996 as a nondestructive technique for quantitative measurements of glycosaminoglycan (GAG) concentration in articular cartilage samples [].Its translation to clinical platforms as a means of interrogating the molecular aspects of cartilage was demonstrated in 1997 with illustrative examples of apparent … 2012-10-01 (dGEMRIC) is a non-invasive imaging method that measures a surrogate for glycosaminoglycan (GAG) concentration in articular cartilage [1].

In the dGEMRIC technique, the negatively charged contrast agent Gd-DTPA 2− (Magnevist, Berlex, NJ) is injected intravenously and diffuses into articular cartilage, with a final concentration inversely proportional to the cartilage GAG concentration 7. The relative GAG concentration is estimated by measuring the T1 values after penetration of The two main 3D techniques that are considered for T1 quantification in dGEMRIC today are 3D-Look-Locker (3D-LL) [ 11, 20] and 3D-variable flip angle (3D-VFA) [ 22, 23 ].
