[Profilographic studies with 99mTc-pertechnetate in joint diseases in children].

Abstract

The inflammatory activity of joints can be stated after intravenous administration of 99mTc-pertechnetate by demonstration of an enrichment of isotope. In 85 out of 111 patients (77%) a good accordance between profilogram and clinical finding could be seen. "False positive" results could be found in juvenile rheumatoid arthritis, ulcerative colitis, reactive arthritis and juvenile gout. In some cases of juvenile rheumatoid arthritis the clinical finding is later obvious than the demonstration by nuclear medicine. "False negative" results mainly can be seen at the wrists of patients with juvenile rheumatoid arthritis and tendosynovitis as well as in already existing radiological changes of the bones. Differential diagnostical evidences of profilography cannot be expected with the investigation technique used here. It, however, may contribute to assure the diagnosis in non-inflammatory joint diseases ("psychogenic rheumatism", lymphatic oedema).
