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

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). magnetic resonance imaging of cartilage (dGEMRIC index, ms).

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.

Patients received 0.2 mg/kg Gd(DTPA) 2− (Magnevist ® , Schering AG, Berlin, Germany) intravenously, followed by a 10 min timed walk. dGEMRIC imaging was performed 60 min after the injection.

Method: Sixty-nine subjects were prospectively included (median age, 42 years; male/female = 32/37) in three cohorts: 10 healthy volunteers, 40 patients with clinically suspected 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). 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. Methods: Twenty-seven participants (age = 28.8 ± 8.6 yrs; BMI = 24.2 ± 2.3 kg m −2; 44% females) diagnosed with FAI syndrome (cam-, pincer- or combined-type FAI morphology concurrent with symptoms) underwent hip MRI with delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) in one of two 3T scanners (Siemens Prisma, Siemens Skyra). The dGEMRIC imaging was performed 60 min after the injection.

Images were analyzed by two independent raters for dGEMRIC indices, PsA MRI scores (PsAMRIS), and All MR imaging was performed on a 3T MR scanner (MAGNETOM Skyra, Siemens Healthcare, Erlangen, Germany) with a 15-channel Tx/Rx knee coil. 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).

MR preiskava, ki omogoča specifično diagnosticiranje zgodnje obrabe Assessment of Cartilage Quality of Metacarpophalangeal Joints in Rheumatoid Arthritis Using Delayed Gd (DTPA)2-enhanced MRI of the Cartilage (dGEMRIC) at 3 T, LL-MKS-MO1A, 9003179, Falk Miese, 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. Therefore, we performed dGEMRIC only at 3 T. Another limitation is the relatively long interval between dGEMRIC and sodium imaging examinations. MATERIALS AND METHODS: The study cohort consisted of 53 patients with symptomatic femoroacetabular impingement (FAI) that were randomly recruited for either iv-dGEMRIC or ia-dGEMRIC studies. 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.
