title: Accuracy of brain scanning in pediatric craniocerebral neoplasms.
abstract: A total of 2,563 children were studied by cerebral radionclide angiography, immediate postinjection blood-pool imaging, and delayed 2- to 4-hr. brain scanning. Of 110 new neoplasms of the brain or skull examined, 90% were detected by these means. The scan did not appear to be as accurate in craniopharyngiomas (6/10) and brainstem tumors (5/6). Thirty-nine recurrent tumors not studied previously all produced positive brain scans. Meticulous positioning of the pediatric patient is necessary at all times for accurate results.
