Of these techniques, only dGEMRIC has so far become clinically use-ful in cartilage repair imaging. a) Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC*) GAG are important to the cartilage tissue’s The Siemens South Africa head office in Johannesburg has implemented a Distributed Energy System (DES) as a solution to tackle Africa’s energy transition. Th 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). 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 Then, sagittal dGEMRIC maps after equilibration in 1mM Gd-DTPA2-for 3 hours, were obtained in the same imaging plane and knee positions (Position A and B). In addition, sagittal T2, T2*, and dGEMRIC maps with the knee extended (flexion 0°) and the femoral shaft oriented 40° to B 0 (Position C) were obtained in two knees, to evaluate the isolated 2009-05-01 2021-01-20 2020-05-29 The MRI imaging was performed using a 1.5 T Siemens Avanto MRI machine (Siemens Healthcare GmbH, Erlangen, Germany).

In dGEMRIC, a high T1 relaxation time represents high sGAG content and a low T1 relaxation time represents low sGAG content.

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 … Delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) in Hip Dysplasia Marcel Dudda, M.D.; et al.

dGEMRIC was performed on a 1.5T Siemens Symphony magnet . Each subject recieved 0.2 mmol/kg of Gd(DTPA) 2 (Magnevist®, Bayer Healthcare) contrast agent, followed by a saline flush.

Immediately after contrast administration , each subject walked for 10 minutes to promote diffusion of the contrast into synovial fluid and cartilage. Anterior femoroacetabular impingement (FAI) is associated with labral tears and acetabular cartilage damage in athletic and young patients.

1 Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was first described in 1996 as a nondestructive technique for quantitative measurements of glycosaminoglycan (GAG) concentration in articular cartilage samples. EVALUATION METHODSThe evaluation included dGEMRIC, isokinetic tests of muscle strength, a functional performance test and calculation of BMI. dGEMRIC A 1.5 T MRI system (Magnetom Vision; Siemens Medical Systems, Erlangen, Germany) with a dedicated knee coil was used for the examinations as previously described 12,20 . Using dGEMRIC, several studies have shown a strong correlation of local joint in-ﬂammation and early cartilage alterations in RA [24,25]. However, to the best of our knowledge, no such data exists for PsA patients. Accordingly, the aim of our study was to assess articular cartilage composition by dGEMRIC across a cohort of PsA patients as dGEMRIC index was calculated by averaging the T1 val-ues in the corresponding 16 central slices (0.9 mm thick).

The dGEMRIC index was analyzed on seven di erent articular facets: the medial and lateral femoral condyle, femoral trochlea, medial and lateral tibial condyle and both patellar facets, before the intra-articular application of stem cells and in any subsequent MRI examination at three, nine, (Magnetom Trio, Siemens Medical Solutions, Erlangen, Germany) with a body-matrix phased-array coil and the subject being examined in supine position. For iv-dGEMRIC, FDA approved Gd (0.4m L/kg, 0,2 mmol Gd/kg, Dotarem, Bayer AG, Leverkusen, Germany) … 2010-11-01 pathology or on medial tibiofemoral dGEMRIC were excluded from the analysis. Missing data were due to self-withdrawal, failure to comply with followup, protocol violation, or motion or other artifacts during MR acquisition. In total, 32 subjects were excluded.

The patients were examined using a standard knee MRI protocol [13] that was developed and used at Oslo University Hospital and included T2 mapping and a dGEMRIC [14]. The patients were scanned with all of the different sequences 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 The changes in dGEMRIC findings and hip morphology between the preoperative visit and the examinations at one and two years following the periacetabular osteotomy were assessed.
