Delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) facilitates non-invasive evaluation of the glycosaminoglycan content in articular cartilage. The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment. 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. published and a few studies reporting on dGEMRIC changes; 6 months,9,239 months,2412 months,9,23and 24 months9posttreatment in humans. Although positive results were obtained, none of these studies could confirm (statistically) significant cartilage quality changes on For KJD such data are not present.

Dgemric

These principles rely on the fact that GAG is the source of the majority of the fixed charge on the cartilage Traditionally dGEMRIC has been performed using a two-dimensional T1-weighted inversion recovery (2D-IR) sequence to acquire data for quantitative T1 mapping [18, 19].The major advantage of this method is the widespread availability of the sequence and desirable contrast properties (cartilage versus fluid). For dGEMRIC, the optimum time window after contrast‐injection (gadopentetate dimeglumine) was defined as the plateau of the T 1 curve of repeated measurements 15–90 minutes postinjection and assessed in all volunteers. Reference values of healthy‐appearing cartilage from all individuals and values in areas of chondromalacia were assessed The dGEMRIC index and indentation stiffness were highly correlated within regions, within cartilage from the same joint, and across cartilage from all the joints, so long as the dGEMRIC index from with dGEMRIC for the detection of cartilage damage? Do the mean acetabular and femoral dGEMRIC indices differ between (2) superior acetabular clock positions with and without impingement and (3)between cam andpincer FAI? METHODS We performed a retrospective, institutional review board– approved, comparative radiological study of 21 hips in 20 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 The dGEMRIC technique can be easily implemented clinically by using a standard 1.5 or 3.0 T magnet.

Two investigations were excluded due to dGEMRIC Samir Sur, MA,1 Tallal Charles Mamisch, MD,2 Timothy Hughes, PhD,3 and Young-Jo Kim, MD, PhD1* Purpose: To determine the feasibility of using a high reso-lution isotropic three-dimensional (3D) fast T1 mapping sequence for delayed gadolinium-enhanced MRI of carti-lage (dGEMRIC) to assess osteoarthritis in the hip. 2012-01-01 Background Biochemical MRI of hip cartilage such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping is increasingly used to judge cartilage quality in the assessment of femoroacetabular impingement (FAI).

Methods: The right knee in 12 asymptomatic volunteers was examined using a 3D Look-Locker sequence on two occasions after an intravenous injection of a double or triple dose of Gd-DTPA2-(0.2 or 0.3 mmol/kg body weight). The relaxation time (T 1) and relaxation rate (R 1 =1/T viously reported relating dGEMRIC to radiographic indices6. 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.

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. The characteristic resistance to compressive forces of healthy cartilage relies on high GAG content. dGEMRIC indices similar to those from their matched controls and in the normal range for hip cartilage. In all but one of the eight subjects the anterior dGEMRIC index was lower than that in the posterior region. Average T1 for Four Slices Patient T1 (ms) Control T1 (ms) No. Sex/Age Anterior Posterior Sex/Age Anterior Posterior The objective of the study are: Evaluate OA progression by evaluating cartilage morphology, cartilage glycosaminoglycan (GAG) content, and joint space changes measured by MRI (3.0T), dGEMRIC index, and radiography, respectively using age-matched control subjects to identify disease related changes.

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.
