high field has the benefit of increased SNR to facilitate high resolution
imaging. However, the lengthened relaxation time requires long scan times to
produce high resolution T1 maps due to the need to allow the
system to return to equilibrium. Here we present a Look-Locker TFEPI sequence
that allows the acquisition of high resolution, 1.25mm isotropic, T1
maps with large volume coverage at 7T in less than 6 minutes.
