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.
