Visualization of brain surface structures with conventional T2-weighted multisection MR images

The surface anatomy scanning (SAS) technique, which displays brain surface structures, has been developed over the past 2 years. The purpose of this study is to shorten the examination time required for surface structure imaging. The SAS technique use a very long TE sequence (e.g., SE 3000,250) with thick sections and a surface coil to enhance CSF on the brain surface. The authors' modified technique uses added multisection images, each appropriately weighted./ A selected sequence is a conventional T2-weighted multisection one (e.g., SE 3000,120), the images of which can be used for SAS and also for routine screening. Furthermore, several surface images with slightly different projection directions are obtained, and they are used for stereographic and cine display
