[Xeroradiography and conventional radiological methods in chronic polyarthritis (author's transl)].

Xeroradiograms and conventional radiographs of the hands of 50 patients with chronic polyarthritis were performed. These were compared with regard to the features which are found in chronic polyarthritis. There were no significant differences between xeroradiography and conventional radiology. Xeroradiography was a little better for demonstrating changes in the soft tissues and erosions, but conventional radiographs were superior in showing osteoporosis, cysts and the absorption of subchondral lamellae. In general, xeroradiography and conventional procedures were of equal value in the diagnosis of chronic polyarthritis. For practical purposes, conventional radiography is to be preferred and xeroradiography may be regarded as an additional procedure, particularly for the investigation of soft tissue changes.
