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 process14.

Thirteen knee imaging studies were performed on a 3 Tesla Siemens TIM Trio scanner (Siemens Medical Solutions, Erlangen, Germany) using a single channel transmit-receive extremity coil. A complete quantitative cartilage imaging study (T1ρ, T2 and dGEMRIC) was collected in two sessions within a four hour period ( Figure 1 ).

The Variable flip angle method with two 3D gradient echo sequences was used for acquisition of images for T1 calculation (MapIt, Siemens Healthcare, Erlangen, Germany). The two sequences had flip angles 5 and 30 respectively. Other scan parameters were: 3Tesla and specific sequences dgemric Siemens a positive structural effect on the proteoglycan content of the articular cartilage of the knee. - An article demonstrating by ultrasound a quantitative gain in articular cartilage of knee osteoarthritis. - A positive medico-economic study in favor of savings in (dGEMRIC*) [3], sodium MR imaging [4, 5], and, very recently, chemical exchange-dependent saturation transfer (CEST) [6]. Of these techniques, only dGEMRIC has so far become clinically use-ful in cartilage repair imaging.

Methods One hundred and forty-eight women (one knee for each subject) aged ≥40 years were included The dGEMRIC was performed as a T1 mapping based on 3-dimensional gradient-echo (3D-GRE) sequence with differ-ent fl ip angle combinations compared to standard IR sequence at 1.5T. We used a Siemens Avanto MRI machine (Siemens Patients who underwent knee arthroscopy in 1999 n = 993 Patients with FCD in one femoral condyle who underwent cartilage dGEMRIC index was calculated by averaging the T1 val-ues in the corresponding 16 central slices (0.9 mm thick). Second, for each of the 4 central thick slices (4 mm thick-ness), the corresponding high resolution dGEMRIC index was calculated from the corresponding 4 thin slices (0.9 mm thickness) and compared. All image analyses were 17 patients with active PsA were evaluated by high-resolution clinical standard morphological and dGEMRIC sequences using a 3T MRI scanner (Magnetom Skyra, Siemens) and a dedicated 16-channel hand coil. Images were analyzed by two independent raters for dGEMRIC indices, PsA MRI scores (PsAMRIS), and total cartilage thickness (TCT). Background: Even though cartilage loss is a known feature of psoriatic arthritis (PsA), little is known about its role in the pathogenesis of PsA. Using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) as a non-invasive marker of the tissue's proteoglycan content, such early (i.e., pre-morphological) changes have been associated with inflammation in rheumatoid dGEMRIC All patients were investigated in a standard 1.5 T MRI system (MAGNETOM Avanto, Siemens AG, Erlangen, Germany) with two flexibleBody Matrixcoils positioneddirectlyoverthehips.

MRISubjects were investigated with dGEMRIC 20.6 years (mean; range 18e23) after the injury, using a standard 1.5 T MRI system with a dedicated knee coil (Magnetom Vision; Siemens Medical Solutions, Erlangen, Germany). MRI with dGEMRIC was more sensitive than morphological MRI, and lower dGEMRIC values were found for clock positions with impingement as detected on 3D-CT.

This could aid in patient-specific diagnosis of FAI, preoperative patient selection, and surgical decision making to identify patients with cartilage damage who are at risk for inferior outcomes after hip arthroscopy. Results: Chondromalacia grade 2-3 had significantly higher CEST values (P = 0.001), lower dGEMRIC (T1-) values (P < 0.001) and higher T2 values (P < 0.001) when compared to the normal appearing cartilage. dGEMRIC and T2 mapping correlated moderately negative (Spearman coefficient r = -0.56, P = 0.0018) and T2 mapping and CEST moderately positive (r = 0.5, P = 0.007), while dGEMRIC and CEST did Elektrifiering, automation och digitalisering kräver innovativa lösningar: Upptäck Siemens som en stark partner, teknisk pionjär och ansvarig arbetsgivare. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification of biochemical cartilage properties.

Objective. Delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) is used to assess cartilage glycosaminoglycan distribution. Our aim was to determine the relationships between self-reported pain and disability, clinical variables, and serum leptin, and dGEMRIC indices in obese subjects with and without clinical knee osteoarthritis (OA).

Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) and contrast-enhanced computed tomography (CECT) have been proposed for diagnostics of proteoglycan loss in osteoarthritis (OA). 1-4 In these methods, anionic contrast agents are hypothesized to distribute into the cartilage in inverse proportion to the spatial distribution of fixed charge density in Thirty-five hips in 35 patients presenting with varying radiographic evidence of arthritis in the hip were imaged using a 3D isotropic fast T1 mapping dGEMRIC sequence (TR 15 msec, TE 3.27 msec, flip angles of 4.1 and 23.5 deg., Matrix size 192/192, 16 cm FoV, voxel size 0.8 x 0.8 x 0.8 mm) and a previously validated fast T1 mapping dGEMRIC sequence (voxel size 0.6 x 0.6 x 4 mm) for comparison.
