title: Combined computed tomographic and radionuclide imaging in the long-term follow-up of children with primary intra-axial intracranial neoplasms.
abstract: Radionuclide and computed tomographic (CT) scanning was performed for the long-term follow-up of 63 patients who had been treated for primary intracranial central nervous system tumors. This group included 23 children with supratentorial lesions and 40 with infratentorial lesions. The results of imaging were correlated with clinical assessment and the results of cytologic evaluation of the cerebrospinal fluid and, when available, surgical or autopsy findings. The sensitivity, specificity, and positive predictive value of both CT and radionuclide scanning were evaluated for each type of tumor. These two modalities play a complementary role in the long-term follow-up of children with primary intra-axial neoplasms.
