Cartilage GAG loss in the acute phase after an anterior cruciate ligament injury assessed by dGEMRIC and synovial fluid analysis. Tiderius C J, Olsson L E,

Background Biochemical MRI of hip cartilage such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping is increasingly used to judge cartilage quality in the assessment of femoroacetabular impingement (FAI). The current evidence is sparse about which of these techniques yields a stronger correlation with histologic cartilage degeneration because of the difficulty in

ISO 10993-3, Biologisk värdering av medicintekniska produkter - Del 3: Provning av genotoxicitet, carcinogenitet och In the course of several studies, both dGEMRIC and T2-mapping were evaluated for this application. It is feasible to differentiate between native cartilage and 18 dgemric= delayed Gadolinium-Enhanced MRI of Cartilage= kvalitativ broskanalys Gd-DTPA 2- Intravenöst i dubbeldos Delay (1-2 timmar) MR undersökning.

2013-07-01 · The dGEMRIC scanning technique was useful in detecting local cartilage repair in a focal defect 1 year after treatment, which was accompanied by clearly improved clinical scores. In addition, local improvement of T1gd was directly related to the improvement of cartilage quality in other joint compartments.

Also regression analysis was performed to show the influence of local repair on cartilage quality at distant locations in the knee. The dGEMRIC index (mean ± sd) at four times (min ± sd) after intravenous injection of double dose Magnevist. The dGEMRIC index was 20–30 % lower in the patients with early OA compared to healthy volunteers (P < 0.003) at all time points, with largest difference at the earlier time points due to faster wash-in of the contrast in the OA cartilage. Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a technique to evaluate cartilage quality by estimation of glycosaminoglycan (GAG) content, a low dGEMRIC index indicates low cartilage quality.

We hypothesized that tibial and femoral Delayed Gadolinium-Enhanced MR Imaging of Cartilage (dGEMRIC) indices would be lower in the medial compartment of the ACL-injured knee than in the contralateral, uninjured knee, and that scan order (i.e., whether the injured or the uninjured knee was imaged first) would not affect the indices.

Question/purpose In this study, our purpose was to determine the correlation between the The dGEMRIC indexof each hip was calculated as the mean T1Gd of its ROI, excluding voxels with T1Gd >1300 ms, according to standard protocol at our institution. dGEMRIC indices were then adjusted for BMI to correct for differ-ences in distribution volume using the formula described by Tide-rius et al.26. Two investigations were excluded due to MRI of Cartilage (dGEMRIC) have been used in trials to assess cartilage quality before joint preserving surgery [7] and in the follow-up of repair procedures [8]. Though MRI T2 mapping is capable of assessing collagen organization [9], the dGEMRIC technique can indir-ectly reflect the proteoglycan concentration [10, 11]. 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).

In this particular study, the B1 variations are shown to be of minor influence at 1.5T and may thus in some carefully tested applications possibly be neglected.

Imaging of Cartilage (dGEMRIC) technique is a well-established method for early assessment of cartilage quality in osteoarthritis [1]. Using this technique, the distribution of Gd-(DTPA)2− contrast agent in cartilage after intravenous injection is assessed with quantitative T 1 mapping. The estimated T 1 is assumed to be indirectly
