Coordinated investigation of cystic astrocytomas by nuclear medicine and neuroradiological techniques.
Astrocytomas are the most common intracranial neoplasm in children. It is necessary to demonstrate preoperatively the location and extent of a possible neoplastic cyst and to differentiate it from the part that is solid. This is achieved through brain scans, computer axial tomography and angiography. Though of considerable help, brain scan and computer axial tomography are insufficient in providing the neurosurgeon with the complete character and geography of the neoplasm necessary for successful surgical treatment. Demonstration of these features can only be elucidated by contrast angiography. Consequently, the coordination of these three techniques permits the precise evaluation of the presence, nature, and operative and postoperative course of cystic astrocytomas.
