A great effort was made to find a perfect diagnostic method for intracranial expanding lesions . Despite the great advances which were associated with pneumoencephalography ,electroencefhalography and angiography of the cerebral vessels, there are some cases where the diagnosis is not established correctly or is made too late. Moreover, there are patients , where the graphic examinations methods indicate their limitations :graphical X-ray methods usually do not visualize the tissue of the expanding process . Moreover , it is important to realize as regards electroencephalographic tracings that the tumour itself is electrically inactive and the sours of disorders in tumours is the surrounding tissue, i.e. the cerebral tissue damaged by the tumour . The experimental findings and character of changes suggested that the uptake of isotopes is not directly related to neoplastic growth. Scintigraphy of brain tumors was originally made by means of standard gammagraphs .Because of the required great differentiating capacity and sensitivity of detection gradually various improvements of gammagraphic devices were introduced . The affect site can be more readily found by a graphic record .It was demonstrated that different expansive processes and tumours ,depending on their histological structure , take up isotope to a different extent at a different time intervals after radiation from any depth of cerebral tissue.
