Images were taken using a Siemens Magnetom Symphony Quan-tum 1.5-T scanner (Siemens AG, Medical Solutions, Erlangen, Ger-many). Single sagittal slice images from the centre of the medial and lateral femoral condyles were taken from the knee with the highest K/L grade (affected knee). 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.

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 105 at 3T (Siemens Skyra, Siemens Healthcare, Germany) was performed prior to arthroscopy. 106 Magnetic resonance imaging107 108 T 2 relaxation time was measured using a multi-slice multi echo spin echo sequence (TR = 109 1680ms, five TE’s between 13.8 and 69ms, ETL = 5, FOV = 160×160mm2, 384×384 matrix, 110 3mm slice thickness).
Methods One hundred and forty-eight women (one knee for each subject) aged ≥40 years were included The dGEMRIC was performed as a T1 mapping based on 3-dimensional gradient-echo (3D-GRE) sequence with differ-ent fl ip angle combinations compared to standard IR sequence at 1.5T. We used a Siemens Avanto MRI machine (Siemens Patients who underwent knee arthroscopy in 1999 n = 993 Patients with FCD in one femoral condyle who underwent cartilage dGEMRIC index was calculated by averaging the T1 val-ues in the corresponding 16 central slices (0.9 mm thick). 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 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.

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.

2C) at 60 minutes after the injection was higher in OA cartilage at lateral femoral condyle than in intact cartilage. Rationale and Objectives. 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.

2014-01-01 · Subjects were investigated with dGEMRIC 20.6 years (mean; range 18–23) after the injury, using a standard 1.5 T MRI system with a dedicated knee coil (Magnetom Vision; Siemens Medical Solutions, Erlangen, Germany). Initially, Gd-DTPA 2− (Magnevist ®, Schering AG, Berlin, Germany) was injected at a dose of 0.3 mmol/kg body weight. 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 The majority of dGEMRIC studies have been in the knee and hip, although there are a number of reports of dGEMRIC applied to the finger joints [12, 50–52] and ankle .

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. Therefore, we performed dGEMRIC only at 3 T. Another limitation is the relatively long interval between dGEMRIC and sodium imaging examinations.
