title: Clinical usefulness of 67gallium scanning in the malignant lymphomas.
abstract: To determine the clinical usefulness of 67 gallium (Ga) scanning in the evaluation of patients with lymphomas, we reviewed 142 total body Ga scans performed on 44 patients with Hodgkin's disease and 53 patients with non-Hodgkin's lymphoma. Fifty-two per cent (123 of 236) of known disease sites were detected on scan. The false-positive rate was less than 5 per cent. The accuracy of detecting lymphoma varied in individual anatomic areas from 33 per cent in the axilla to 73 per cent in the thorax. In eight patients with bone involvement, all bone lesions were detected on scan. The size of the lesion appeared to influence accuracy, since tumors greater than 3 cm in diameter were more often positive.
