Third, dGEMRIC is a rather complex MRI technique that can be influenced by the patient's body mass index, the Fig. 6 Mapping of the regional distribution of the dGEMRIC values for the 2020-04-01 dGEMRIC technique uses either a two-dimensional (2D) or 3D spin-echo inversion recovery or saturation recovery sequence with varying inversion time (TI) or repetition time (TR). These series of images are then post-processed to obtain the T1 maps (14). Fast T1 mapping techniques such as the Look-Locker (15) and DESPOT (16) techniques are available. 2016-10-05 2013-09-25 Purpose To determine the feasibility of using a high resolution isotropic three‐dimensional (3D) fast T1 mapping sequence for delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) to assess osteoarthritis in the hip. Materials and Methods T1 maps of the hip were acquired using both low and high resolution techniques following the administration of 0.2 mmol/kg Gd‐DTPA2‐ in 35 patients 2006-01-01 This review describes the most prominent quantitative MRI techniques to date—dGEMRIC, T2. mapping, T1rho mapping, and sodium imaging.

MRI of cartilage (dGEMRIC) is a previously presented method for identification of early OA using magnetic resonance imaging  The delayed gadolinium enhanced MRI of cartilage (dGEMRIC) technique is the only non-invasive means to estimate proteoglycan (PG) content in articular  MR/CT workflow to enable clinical implementation of the technique. work was to establish dGEMRIC as a method at 7 T by a field strength. In the course of several studies, both dGEMRIC and T2-mapping were as an additional effect size for the evaluation of surgical cartilage repair techniques.

AU - Bittersohl, Bernd. PY - 2015. Y1 … Up to the levels of AF and NP, this is reproducible in MRI in dGEMRIC technique, but not in X-ray or standard MRI sequences. Potentially, the MRI in dGEMRIC technique can be used as a non-invasive in vivo indicator for disc degeneration in the cervical spine.

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. Materials and methods.

The dGEMRIC technique is based on the electrical polarity of gadolinium [Gd (DPTA)2− ions] and glycosaminoglycans in the joint.

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. 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 ].

Heiles3 1Orthopaedics To determine the feasibility of using a high resolution isotropic three‐dimensional (3D) fast T1 mapping sequence for delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) to assess osteoarthritis in Since our knowledge of both the measurement properties of these imaging techniques, and the in-vivo efficacy of CH, is insufficient to design a definitive clinical trial, we performed a pilot study to determine if dGEMRIC and T2 mapping can discriminate changes in knee hyaline cartilage among participants taking a CH preparation (Fortigel ®) compared to those taking placebo. Abstract. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a new technique to study cartilage glycosaminoglycan (GAG) content. The negatively charged contrast agent Gd-DTPA2-, injected intravenously, distributes in the cartilage inversely to the likewise negatively charged GAG. DOI: 10.1002/jmri.21869 Corpus ID: 1030069.
