Against this background and on the basis of high-resolution morphological and compos-itional MRI techniques (i.e., dGEMRIC… 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 gadolinium-enhanced magnetic resonance imaging of cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the spin-lattice relaxation time or T1 relaxation time. 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.

2016-10-05 In conclusion, the findings in this work suggest that when performing dGEMRIC measurements using the 3D-VFA technique the variations in the B1 field should be considered, especially at 3T. In this particular study, the B1 variations are shown to be of minor influence at 1.5T and may thus in some carefully tested applications possibly be neglected. Standardized dGEMRIC maps of the weight-bearing portion of a representative hip articular cartilage, superimposed to GRE coronal images. Values smaller than zero indicate GAG concentration lower The dGEMRIC MR T1 map is reconstructed from images acquired consec- protocol lasted approximately 15 min.

The dGEMRIC indexof each hip was calculated as the mean T1Gd of its ROI, excluding voxels with T1Gd >1300 ms, according to standard protocol at our institution.

This study evaluates dGEMRIC in patients with preradiographic degenerative cartilage changes. Seventeen knees in 15 patients (age 35-70) with arthroscopically v …. Delayed contrast-enhanced MRI of cartilage 2013-07-01 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 We hypothesized that tibial and femoral Delayed Gadolinium-Enhanced MR Imaging of Cartilage (dGEMRIC) indices would be lower in the medial compartment of the ACL-injured knee than in the contralateral, uninjured knee, and that scan order (i.e., whether the injured or the uninjured knee was imaged first) would not affect the indices. imaging of cartilage, abbreviated dGEMRIC, can be used to estimate the GAG content of cartilage.

Variation in cartilage thickness is a source of error in dGEMRIC studies that should be considered. Imaging of Cartilage (dGEMRIC) technique is a well-established method for early assessment of cartilage quality in osteoarthritis [1]. Using this technique, the distribution of Gd-(DTPA)2− contrast agent in cartilage after intravenous injection is assessed with quantitative T 1 mapping. The estimated T 1 is assumed to be indirectly The uptake of contrast agent was found to be from the superficial region of the cartilage, with diffusion into the deeper parts, and this affects the interpretation of bulk dGEMRIC measurements.

A contrast medium is used, the concentration of which in the cartilage is inversely proportional to the amount of GAG. 2018-04-01 · Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a validated imaging technique to evaluate cartilage quality in vivo. dGEMRIC is estimating the content of glycosaminoglycans (GAG) which is essential for the biomechanical properties of the cartilage and decreases early in the OA process 14. Background The dGEMRIC (delayed Gadolinium-Enhanced MRI of Cartilage) technique has been used in numerous studies for quantitative in vivo evaluation of the relative glycosaminoglycan (GAG) content in cartilage. The purpose of this study was to determine the influence of pre-contrast T1 and cartilage thickness when assessing knee joint cartilage quality with dGEMRIC. Methods Cartilage measurements. The Gd concentration in the superficial layer supports dGEMRIC findings that cartilage has an adaptive capacity to exercise. Decreasing physical activity leads to a decrease in GAG content in the cartilage.
