Plain radiographs of trabecular bone show a distinct pattern. Osteoporosis results in characteristic changes in this pattern and distinctive differences in the appearance of healthy bone and osteoporotic bone. The Singh index is used to assess patterns of trabecular loss. Although of historical interest, it is no longer used in the United States. [43]

The Singh index grading system has always been considered too variable for diagnosis or epidemiologic studies. However, advances in image processing techniques have shown its promise as a method that can overcome the limitations of observer grading. Despite the growing body of evidence that such techniques may be useful, results so far are inconclusive; they may yet provide a tool for the study of osteoporosis. [43]
