Three-dimensional magnetic resonance imaging has several advantages over the 2-dimensional technique. It makes the visualisation of non-planar structures easier and, along with that, volume measurements; although less important for straight forward radiological diagnosis, this is very useful for treatment planning, the teaching of anatomy and notably the development of magnetic resonance angiography. Until recently though, it has generally been too complicated and time consuming to produce and present three-dimensional data for it to be of practical use. However recent advances in technology have, to some extent, overcome these limitations. Data aquisition has been improved with fast imaging techniques, such as gradient echoes, and data processing can be done within minutes using the new generation of computers. This book gives an overview of some of the basics and application of three-dimensional MRI presented at a meeting in Obergurgl, Austria in the spring of 1992. It is a valuable contribution to the understanding of three-dimensional MRI and will
