title: Computerized transaxial tomography and cerebral serial scintigraphy in intracranial tumors--rates of detection and tumor-type identification: concise communication.
abstract: In 215 cases of intracranial tumors with subsequent histological identification, computerized transaxial tomography (CTT), and cerebral serial scintigraphy (CSS) with [99mTc] pertechnetate were carried out to compare the efficiency of each method in detecting and classifying such tumors. With a tumor detection rate of 99%, CTT turned out to be superior to CSS (91%). On the other hand, CSS findings enhanced the CTT rate of correctly identified tumor types in meningiomas from 85 to 92% and in high-grade gliomas from 82 to 89%. In metastases, low-grade gliomas, and various other tumors, CSS supported CTT by confirming a number of these tumor types. Therefore, the most important use of CSS in intracranial tumors today is its role as a supplement to CTT in order to establish and confirm type-specific diagnoses.
