3D feature severity mapping of the hip with computed tomography reveals patterns of radiological osteoarthritis T.D. Turmezei, D.J. Lomas, M.A. Hopper, K.E. Poole Osteoarthritis and Cartilage Volume 21, (April 2013) DOI: 10.1016/j.joca.2013.02.399 Copyright © 2013 Terms and Conditions

Figure 1 3D feature severity mapping of the proximal femur for osteophyte severity scores 1-3, Sectors in grey were excluded from the analysis (fovea and anterior reaction area). Only the most severe feature score from each hip contributes to the maps according to its severity, nmax = the number of hips in the most frequent sector for a given score (asterisked), ntotal = the total number of hips with that score. Sectors are shaded from white to red as a proportion of the nmax sector, thus representing the severity distribution in 3D. An additional 82 hips had a severity score of 0.
