[Axial computerized tomography with high resolution matrix (160 x160)]

The evaluation 1250 patients investigated with computerized tomography reveals a very high detection rate with brain tumours and other intracranial space-occupying lesions. From 246 brain tumours 238 = 96,7 per cent could be diagnosed in the plain scan. After contrast enhancement only one false negative case, a tumour of the corpus callosum, remained. With emergency cases and neuropediatric diseases computerized tomography is the most informative investigation at all. The high definition matrix 160 x 160 in connection with the patient's movements correction has led to further improvement of resolution and visibility of details of intracranial anatomy and pathology in CT-scans.
