Abstract

A review of 16 recent publications purporting to provide the relaxation times of CSF reveals a considerable disparity in the quoted results, by a factor of 5 in terms of T1 (range 1000–5500 ms) and by a factor of 18 for T2 (range 166–3052 ms). In this article measurements are performed independently on both a spectrometer and an imager. The results indicate that for CSF Ti is greater than 3000 ms and T2 is greater than 2000 ms at an operating frequency of 6 MHz. The vast differences in relaxation behaviour between CSF and other body tissues have considerable clinical implications and present profound diagnostic opportunities. The application of this knowledge to ventriculography, myelography and image contrast methodology is discussed. (J Comput Assist Tomogr 11: 203–207, 1987)
