title: [Scintigraphic examinations of sacroiliacal joints in patients with early forms of ankylosing spondylitis].
abstract: In contrast to the X-ray examination the scintigraphy of the sacroiliacal joints in the early phase of the ankylosing spondylarthritis allows an evidence to the local processes of bone reconstruction directly depending on their activity. Positive findings of scintigraphy have a high sensitivity and a low specifity. They demand a further differential-diagnostic clarification. In this sense, supplementing the X-ray findings, the scintigraphy brings valuable informations for the early diagnostics of ankylosing spondylarthritis. The radiation exposure of the gonads which is smaller by factor 3 in comparison to the X-ray examination of the pelvis is an essential advantage in the above all young patients. The valuation of the scintigramme must be performed in close connection between clinical rheumatologists and specialists in nuclear medicine. Our results show that longitudinal examinations let expect a further improvement of the evidence.
