Tumor visualization using /sup 67/Ga scintigraphy in children

One hundred and twenty-two children suspected of having malignant disease were examined by /sup 67/Gallium scintigraphy. True-positive detection was obtained in 22 patients before treatment and true-negative in 22. False-negative scans were obtained in 5 children with primary adrenal neuroblastoma. Local recurrence and/or metastases were detected in 29 of 58 children previously treated for malignant disease. For malignant disease, diagnostic sensitivity was 78% and diagnostic specificity 79%. It is concluded that /sup 67/Ga scintigraphy should be used for primary visualization and control of malignant tumors in children.
