Although several reports were published on the effectiveness of computer tomography (CT) in the diagnosis of intracranial tumours (Ambrose 1973, Baker et al. 1974, Gawler et al. 1974, New et al. 1974, 1975, Paxton & Ambrose 1974, Greitz 1975), these early results do not seem to have been compared with those obtained following the technical improvements in the field of computer tomography. These improvements include the use of a higher matrix and the routine intravenous administration of high doses of contrast material. In previously published material, infratentorial tumours seemed to be less accurately demonstrated than supratentorial lesions. A review of the more recent cases of posterior fossa tumours examined at the Department of Neuroradiology was therefore made and the results were related to those earlier obtained (Greitz 1975). An attempt was also made to assess the theoretical limitations of detecting small intracranial tumours.
