Brain imaging using multislice CT: a personal perspective

University Hospital of Wales, Heath Park, Cardiff CF14 4XW, UK

This article outlines the use of multislice CT of the brain with regard to routine scanning, as well as high speed and/or high resolution multiplanar reconstructions. It describes in detail the recent developments in cerebral perfusion scanning and CT arteriography. It will also outline the approach of the University Hospital of Wales to imaging with this new technology, emphasizing the differences between helical and non-helical techniques. Most of the images are taken from 16-slice machines, but the methods described are applicable to 4- and 8-slice scanners, and can readily be modified for the forthcoming 64-detector array equipment that will be available within the next few months.
