FLAIR imaging is the most important technique for lesion
detection in the human brain. To our knowledge, there is
still no 7T alternative available which delivers images
with similar dark-fluid T2 contrast, as the gold
standard at 3T. In this work we present a fluid
suppressed Turbo-Spin-Echo sequence for ultra-high-field
application which bridges this gap. Our approach is
based on a double inversion recovery preparation. To
obtain images comparable with 3T results, prolonged
tissue T1, and high field issues such as B0/B1
inhomogeneities had to be addressed. Furthermore, an
efficient fat suppression technique had to be
implemented to enhance image quality.
