dGEMRIC scans were performed on 1.5 T General Elec-tric Sigma Excite scanners equipped with TwinSpeed gradi-ents (GE Healthcare, Waukesha, WI) approximately 90 min after an IV injection of Gd-DTPA2 at 0.2 mmol/kg body weight. dGEMRIC was acquired by either 2-D or 3-D sequence. (dGEMRIC)15, T1rho mapping16, and diffusion-weighted imaging (DWI) have been introduced as effective methods of evaluating regenerative cartilage17. Previous studies have clarified the re-lationships between quantitative MRI techniques and biochemical assessments. T2 values indicate comprehensive cartilage status, Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) has been shown to quantify regional variations of glycosaminoglycan (GAG) concentrations which is an indicator of early cartilage degeneration. Part 2: dGEMRIC data were previously reported on 19 asymptomatic volunteers (BMI 18-43, Mean: 27±6) and 30 OA patients (BMI 22-39, Mean = 29±4) [3, 4].

Methods Cartilage measurements.

Objective: To investigate the ability of delayed gadolinium-enhanced magnetic resonance (MR) imaging of cartilage (dGEMRIC) and T2 mapping to evaluate the quality of repair tissue after microfracture. Design: Twelve knees from 12 goats were studied. An osteochondral defect (diameter, 6 mm; depth, 3 mm) with microfracture was created in the weight-bearing aspect of both the medial and lateral

Values smaller than zero indicate GAG concentration lower The dGEMRIC MR T1 map is reconstructed from images acquired consec- protocol lasted approximately 15 min. utively with different inversion times (TIs). In patients, the dGEMRIC protocol [10] was performed Automated image registration may improve dGEM- twice with an interval of 7 days (range 5–14 days). 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.

Delayed contrast-enhanced MRI of cartilage dGEMRIC. The contrast medium Gd‐DTPA 2‐ (Magnevist, Schering Ag, Berlin, Germany) is a water‐soluble biochemically inert chelate complex that is eliminated through glomerular filtration with a plasma half‐life of about 90 min (). 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 2013-07-01 · The dGEMRIC scanning technique was useful in detecting local cartilage repair in a focal defect 1 year after treatment, which was accompanied by clearly improved clinical scores.

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 2018-06-02 Delayed gadolinium-enhanced magnetic resonance imaging of cartilage, abbreviated dGEMRIC, can be used to estimate the GAG content of cartilage. A contrast medium is used, the concentration of which in the cartilage is inversely proportional to the amount of GAG. 2021-03-19 Background: Even though cartilage loss is a known feature of psoriatic (PsA) and rheumatoid arthritis (RA), research is sparse on its role in the pathogenesis of PsA, its potential use for disease monitoring and for differentiation from RA. We therefore assessed the use of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) to evaluate biochemical cartilage changes in 2016-02-11 The delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) index is highly correlated to mechanical stiffness, and, although not as good as a direct mechanical measurement, the index can be used The average dGEMRIC index ranged from 570 ms (no dysplasia), to 550 ms (mild dysplasia), to 500 ms (moderate dysplasia), to 420 ms (severe dyplasia). This study demonstrates that biochemical MRI (i.e., dGEMRIC scans) correlates better with clinical important parameters in hip dysplasia than do traditional radiographic measures of OA, thus suggesting that this is a valid metric to be used in clinical studies … 2018-04-01 Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a technique to evaluate cartilage quality by estimation of glycosaminoglycan (GAG) content, a low dGEMRIC index indicates low cartilage quality.

This article reviews the recent application of delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and discusses its use for assessing cartilage quality in the hip joint. dGEMRIC is more sensitive to early cartilage changes in osteoarthritis than are radiographic measures and might be a helpful tool for assessing cartilage quality.

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.
