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.

This definition approximates grade 2 knee OA based on the Kellgren and Lawrence scale 36 . 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).

dGEMRIC – diagnosticiranja obrabe hrustanca. MR preiskava, ki omogoča specifično diagnosticiranje zgodnje obrabe Background The dGEMRIC (delayed Gadolinium-Enhanced MRI of Cartilage) technique has been used in numerous studies for quantitative in vivo evaluation of the relative glycosaminoglycan (GAG) content in cartilage. The purpose of this study was to determine the influence of pre-contrast T1 and cartilage thickness when assessing knee joint cartilage quality with dGEMRIC. Methods Cartilage The dGEMRIC method used in our study, and that was based on a dual–flip-angle technique, is sensitive to B 1 inhomogeneities, which are even worse at higher field strengths.

Axial and sagittal PD-weighted images with fat saturation, and T1-weighted 3D VIBE images were acquired for morphological analysis. Introduction. 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.

RI was performed in supine position at a 1.5 Tesla (T) system (Magnetom Avanto, Siemens, Erlangen, Germany) using a body matrix-phased array coil.

MR examinations were performed on a Siemens 1.5 T system (Magnetom Avanto, Siemens, Erlangen, Germany) and a body matrix phased array coil. The dGEMRIC scans were obtained after a double dose (0.4 mL/kg) intravenous injection of FDA approved contrast agent Magnevist (Gd-DTPA2; Berlex Laboratories, Wayne, NJ). Patients were

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.

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).

Background Lesions in the meniscus are risk factors for developing knee osteoarthritis (OA), not least because of the role of the meniscus in the pathological progression of OA. Delayed gadolinium enhanced MRI of cartilage (dGEMRIC) has extensively been used to identify pre-radiographic cartilage changes in OA. In contrast, its counterpart with regard to examination of the meniscus, gadolinium
