Comparison of radiograph‐based texture analysis and bone mineral density with three‐dimensional microarchitecture of trabecular bone

Abstract

Digital radiographs, widely available and economically viable, are an alternative method for evaluating bone microarchitectural structure.

European guidance for the diagnosis and management of osteoporosis in postmenopausal women

“…cross-sectional moment of inertia, hip axis length, cortical thickness, trabecular bone score, Hurst parameters). X-ray-based technology is becoming available to estimate these components of bone strength which may have a future role in fracture risk assessment [20–23]. …”

Image features for misalignment correction in medical flat‐detector CT

“…By now, they are very common among medical image analyzing tasks, especially for classification problems. 19,20 If the original gray-level image I of size U × V has Q different intensities, the co-occurrence matrix of I is of size Q × Q. It is defined by its components C α, d (i, j) according to Eq.…”

Long range node‐strut analysis of trabecular bone microarchitecture

“…However, these techniques are not comparable to the method presented in the present study as they are based on projections of a 3-dimensional trabecular network on a 2-dimensional plane, whereas our method is applied to 2-dimensional sections obtained through the 3-dimensional trabecular network. Nevertheless, Ranjanomennahary et al very recently showed some significant correlation did exist between radiograph based texture analysis and µCT based unbiased 3-dimensional measures of trabecular microarchitecture 47 . Apostol et al compared 3-dimensional measures of micro-architecture based on 3-dimensional synchrotron radiation CT with more than 350 texture parameters obtained from simulated radiographs that were created from the synchrotron radiation CT data sets 48 .…”
