High‐resolution multi‐T₁–weighted contrast and T₁ mapping with low sensitivity using the fluid and white matter suppression (FLAWS) sequence at 7T

Purpose To demonstrate that fluid and white matter suppression (FLAWS) imaging can be used for high‐resolution T 1 mapping with low transmitted bias field ( ) sensitivity at 7T. Methods The FLAWS sequence was optimized for 0.8‐mm isotropic resolution imaging. The theoretical accuracy and precision of the FLAWS T 1 mapping was compared with the one of the magnetization‐prepared two rapid gradient echoes (MP2RAGE) sequence optimized for low...
