title: [Scope and limitations of cranial computerized tomography (author's transl)].
abstract: Cranial computerized tomography (CT) has revolutionized the scope of diagnostic procedures in intracranial diseases. The method is based on the quantitative registration of x-ray absorption and enables many different pathological features within the skull to be directly visualized for the first time on the tomogram. Cerebral haemorrhage and encephalomalacia can be immediatley differentiated on the basis of the totally different appearance on CT. In the case of tumours, the additional administration of the contrast medium intravenously provides enhancement of the diagnostic evidence. Atrophic processes can be diagnosed by means of CT without recourse to additional neuroradiological methods and this facilitation is of particular value in neuropaediatrics. Orbital processes can be easily spotted due to the high definiation matrix of image. The limitations of CT are based on physical conditions.
