OBJECTIVE To assess and compare subregional and whole T1rho values (median±interquartile range) of femorotibial cartilage and menisci in patients with doubtful (Kellgren-Lawrence (KL) grade 1) to severe (KL4) osteoarthritis (OA) at 3T. MATERIALS AND METHODS 30 subjects with varying degrees of OA (KL1-4, 13 females, 17 males, mean age±SD=63.9±13.1 years)(More)
—Research computing in the social sciences requires access to statistical software and quantitative tools that perform embarrassingly parallel computation at moderate scale, large memory to fit entire data sets, and secure storage for potentially confidential data. The Research Computing Environment (RCE) was designed as a three-tier system to satisfy these(More)
OBJECTIVES To investigate the value of diffusion tensor imaging (DTI) of articular cartilage to differentiate healthy from osteoarthritis (OA) subjects in all cartilage regions. METHODS DTI was acquired sagittally at 7 T in ten healthy and five OA (Kellgren-Lawrence grade 2) subjects with a line scan diffusion tensor sequence (LSDTI). Three healthy(More)
PURPOSE To compare and assess subregional, compartmental, and whole T1rho values of menisci in patients with doubtful-minimal (Kellgren-Lawrence [KL] grade 1-2) as compared to moderate-severe (KL3-4) osteoarthritis (OA) and healthy controls at 3 Tesla (T). MATERIALS AND METHODS Forty-six subjects were included in the study and subdivided into three(More)
OBJECTIVE To assess the relationship between knee alignment and subregional T1ρ values of the femorotibial cartilage and menisci in patients with mild (Kellgren-Lawrence grade 1) to moderate (KL3) osteoarthritis (OA) at 3T. MATERIALS AND METHODS 26 subjects with a clinical diagnosis of KL1-3 OA were included and subdivided into three subgroups: varus,(More)
The compartment-specific lipid changes in femoral-tibial bone of healthy controls and mild osteoarthritis (OA) patients were quantified at 3.0 T. Healthy volunteers [Kellgren-Lawrence (KL) grade = 0; n = 15, 4 females, 11 males, mean age 39 ± 16 years, age range = 24-78 years] and mild OA patients (KL = 1, 2; n = 26, 12 females, 14 males, mean age 61 ± 14(More)
