Abstract
The authors compared high-signal-intensity flow-related artifacts present w ith a conventional two-dimensional (2D) fluid-attenuated inversion recovery (FLAIR) sequence with those seen with a single-slab, three-dimensional (3D ) FLAIR sequence. Four readers graded the subarachnoid space and intraventr icular artifacts, the pulsation artifacts, and the conspicuity of cranial n erves in the posterior fossa. For all comparisons, differences between 2D a nd 3D images were highly statistically significant, with 3D imaging being s uperior in all cases.
