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). 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.

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.

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.

MR IMAGINGThe MR images were performed on a 1.5T magnet (Symphony; Siemens, Erlangen, Germany) using a quadrature knee coil (Siemens, Erlangen, Germany). Since we intended to perform the dGEMRIC analyses on the femoral and tibial articular cartilage from a single, 3 mm-thick slice through the median plane of the medial femoral condyle (Fig. 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.

Longitudinal assessment of femoral knee cartilage quality using contrast enhanced MRI (dGEMRIC) in patients with anterior cruciate ligament injury – comparison with asymptomatic volunteers In this observational longitudinal study we estimate knee joint cartilage glycosaminoglycan (GAG) content, in patients with an acute anterior cruciate ligament (ACL) injury, with or without a concomitant

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. The Variable ﬂip angle method with two 3D gradient echo sequences was used for acquisition of images for T1 calculation (MapIt, Siemens Healthcare, Erlangen, Germany).
