Autologous lymphocytes were labeled with ln-111 oxine in 26 patients with chronic inflammatory disease. Whole body gamma camera scans were performed at 24 and 48 hours post injection. Activity was normally seen in spleen, liver, bone marrow, and cervical and inguinal lymph nodes; any activity outside there areas was considered abnormal. Five out of 11 patients with proven or suspected chronic osteomyelitis had positive scans. Four out of five patients with chronic arthritic diseases had positive scans.
