Predicting erosive disease in rheumatoid arthritis. A longitudinal study of changes in bone density using digital X-ray radiogrammetry: a pilot study

Computerized radiogrammetry from digitized images can predict at 1 yr those patients with RA who will become erosive at 4 yr. A larger prospective study is required to confirm these findings; however, these results show some promise as a method of targeting those patients who require more aggressive, expensive therapy.
