Fast three‐dimensional imaging of cerebrospinal fluid

The RARE method is based on the principle of echo imaging to generate images with high T2 contrast. Since RARE is a fast imaging method, it can be used to acquire a high‐resolution three‐dimensional data set in less than 15 min. Thin slices from such a three‐dimensional data set provide detailed information about the ventricular system. © 1987 Academic Press, Inc.
