(a) Coronal fluid-attenuated inversion recovery (FLAIR) image utilizing a typical (antemortem) inversion time of 2000 ms at which nulling of the water signal normally occurs in the living subject. On this post-mortem sequence of a cooled subject, the cerebrospinal fluid (CSF) fails to suppress. (b) Coronal FLAIR image of the same post-mortem study as in (a) but with an inversion time of 1200 ms utilized. The CSF has now suppressed satisfactorily.
