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.

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.

Other relationships: disclosed no relevant relationships. 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.

1 ROC-analysis demonstrated non-significant differences of T2 mapping vs CEST (P = 0.14), CEST vs dGEMRIC (P = 0.89), and T2 mapping vs dGEMRIC (P = 0.12). Conclusion: CEST is able to detect normal and damaged cartilage and is non-inferior in distinguishing both when compared to dGEMRIC and T2 mapping. Similar to the knee [ 4, 34 ], dGEMRIC is a promising tool to quantify cartilage healing or degeneration before and after joint-preserving hip surgery and to monitor the natural course of hip diseases.

The objectives of this study were to measure the parallel changes of transverse relaxation times (T 2), spin-lattice relaxation time in the rotating frame (T 1ρ), and the delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC)-T 1 mapping of human knee cartilage in detecting cartilage degeneration at 3.0T.

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.

Methods: The right knee in 12 asymptomatic volunteers was examined using a 3D Look-Locker sequence on two occasions after an intravenous injection of a double or triple dose of Gd-DTPA2-(0.2 or 0.3 mmol/kg body weight). The relaxation time (T 1) and relaxation rate (R 1 =1/T 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 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).
