The diagnostic value of CT for radiotherapy of cerebral tumors
The paper deals with CT followup studies on 73 patients with cerebral tumors who received radiotherapy. The value of CT for the indication of radiotherapy, for followup therapy and for the demonstration of therapeutic success are discussed. Since the cerebral tumors become visualized by means of CT in their entire extent and can be differentiated from perifocal edema, the question arises whether radiotherapy should consist of higher doses in the future. It is also suggested that the "clinical malignancy" may be used to compare the behavior of cerebral tumors when there is no exact histological classification. The possible histopathological effects of radiotherapy (edema, necrosis) and their…
The role of computed tomography in the diagnosis of brain tumors in infants and children.
CT has considerably facilitated the diagnosis of intracranial tumors, especially in infants and children. The authors review their experience with a series of 260 children with proven brain tumors. In most cases CT is so conclusive that other diagnostic techniques are no longer often needed. Pneumoencephalography in particular has largely been replaced by CT in recent years in the authors' departments, and the frequency of central ventriculography with contrast material has decreased substantially. Particular diagnostic difficulties with regard to tumors near to or within the caudal brain stem, some posterior fossa tumors, small vermian tumors, and tumors of the cerebral hemispheres are dis…
