Abstract
The objective of this study was to compare conventional and KRISP (k-space reordered by inversion time at each slice position) fluid-attenuated invers ion recovery (FLAIR) sequences in high grade gliomas for artifact control, conspicuity of intracranial structures, and lesions as well as sensitivity to contrast enhancement. Artifacts were lower with the KRISP FLAIR sequence , and the conspicuity of all assessed structures and lesions was better. Th e degree of contrast enhancement was similar with T1-weighted and KRISP FLA IR sequences.
