Abstract
In 125 cases of intracranial tumors with subsequent histological identification, computerized transaxial tomography (CTT), and cerebral serial scintigraphy (CSS) with [99mTc] pertechnetate were done to compare the efficiency of each method in detecting and classifying such tumors. With a tumor detection rate of 99%, CTT was superior to CSS (91%). CSS findings enhanced the CTT rate of correctly identified tumor types in meningiomas from 85-92% and in high-grade gliomas from 82-89%. In metastases, low-grade gliomas and various other tumors, CSS supported CTT by confirming a number of these tumor types. The most important use of CSS in intracranial tumors today is its role as a supplement to CTT to establish and confirm type-specific diagnoses.
