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.

The global mean T1 values (mean of all radial ROIs) were 519 ± 108.5 ms for DDH and 550 ± 81.2 for FAI (P = 0.258, Table II). 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. 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.

2018-04-01 The dGEMRIC Index was 14.4% lower in the medial index compartment (374 61 ms, mean SD) than in the lateral reference compartment (437 59 ms, mean SD) (P<0.001). The dGEMRIC Index of the medial diseased compartment correlated positively with both knee ﬂexor (r¼0.50, P¼0.001) and knee extensor Using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) (Magnetom Skyra, Siemens) and a dedicated 16-channel hand coil. 2020-01-01 using 3D dGEMRIC at two different doses of the contrast agent Gd-DTPA2-. 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).

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 dGEMRIC Index was 14.4% lower in the medial index compartment (374 61 ms, mean SD) than in the lateral reference compartment (437 59 ms, mean SD) (P<0.001). The dGEMRIC Index of the medial diseased compartment correlated positively with both knee ﬂexor (r¼0.50, P¼0.001) and knee extensor Interestingly, when we compared results from our previously published article assessing the one year effect after intra-articular injection of autologous microfragmented adipose tissue, where out of 331 dGEMRIC measurements, 175 measurements (82.6%) were showing changes with a greater magnitude than 15%, while the remaining 37 dGEMRIC measurements (17.5%) were showing relevant decrease, it 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).
