Digital X-ray radiogrammetry DXR is an effective and sensitive modality for monitoring periarticular osteoporosis which is among the earliest features of rheumatoid arthritis preceding bone erosions. DXR is a promising technique which can provide quantitative data that allow early diagnosis. During the course of rheumatoid arthritis it can be deployed in combination with established X-ray scoring methods to inform decisions regarding the optimal therapy to prevent joint destruction. Introduction In a well documented and extensive study of peripheral bone loss in established rheumatoid arthritis RA Hoff and colleagues 1 evaluated bone loss in the hand using digital X-ray radiogrammetry DXR and dual energy X-ray absorptiometry DXA . They compared peripheral demineralization with central bone loss quantified by axial DXA measurements at the lumbar spine and femoral neck considering disease duration over an observation period of 2 years. This carefully conducted study revealed significant peripheral hand bone loss estimated by
