Journal ArticleDOI
Double echo steady state magnetic resonance imaging of knee articular cartilage at 3 Tesla: a pilot study for the Osteoarthritis Initiative
Felix Eckstein,Martin Hudelmaier,Wolfgang Wirth,Berthold Kiefer,Rebecca D. Jackson,Joseph S. Yu,Charles B. Eaton,Erika Schneider +7 more
TL;DR: Testing the accuracy and precision of knee cartilage qMRI with a fast double echo, steady state (DESS) sequence with water excitation at 3 T permits accurate and precise analysis of cartilage morphology in the femorotibial joint.
Journal ArticleDOI
Recent advances in osteoarthritis imaging—the Osteoarthritis Initiative
TL;DR: The rationale and design of the OAI and its cohort are described, imaging protocols and image analyses completed to date are discussed, and published methodological and applied imaging research that has emerged from OAI pilot studies and OAI data releases are described.
Journal ArticleDOI
Accuracy and precision of quantitative assessment of cartilage morphology by magnetic resonance imaging at 3.0T.
Felix Eckstein,H. Cecil Charles,Robert J. Buck,Virginia B. Kraus,Ann E. Remmers,Martin Hudelmaier,Wolfgang Wirth,Jeffrey L. Evelhoch +7 more
TL;DR: Quantitative MRI measurement of cartilage morphology at 3.0T was found to be accurate and tended to be more reproducible than at 1.5T, and may provide superior ability to detect changes in cartilage status over time and to determine responses to treatment with structure-modifying drugs.
Journal ArticleDOI
A Technique for Regional Analysis of Femorotibial Cartilage Thickness Based on Quantitative Magnetic Resonance Imaging
Wolfgang Wirth,Felix Eckstein +1 more
TL;DR: The computation of regional cartilage thickness values from segmented MR images is shown to be highly reproducible and robust under conditions of joint repositioning and may substantially enhance the ability of quantitative MRI to monitor structural changes in osteoarthritis at narrow time intervals.
Journal ArticleDOI
One year change of knee cartilage morphology in the first release of participants from the Osteoarthritis Initiative progression subcohort: association with sex, body mass index, symptoms and radiographic osteoarthritis status.
Felix Eckstein,Susanne Maschek,Wolfgang Wirth,Martin Hudelmaier,Wolfgang Hitzl,B. Wyman,Michael C. Nevitt,M-P. Hellio Le Graverand +7 more
TL;DR: In this sample of the OAI progression subcohort, the greatest, but overall very modest, rate of cartilage loss was observed in the weight-bearing medial femoral condyle.
