Recently, a new high quality myelin water imaging method, direct visualization of short transverse relaxation time component (ViSTa) has been developed. The ViSTa signal is primarily from short T₂* in the range of myelin water. In this study, we assessed 3D ViSTa sequence for 7T MR imaging which can cover the whole brain. Taking advantage of higher SNR at 7T, ViSTa using 7T MRI provided high-resolution and high-quality myelin water images generating a whole brain volume in clinically reasonable time. And the method successfully detected demyelinated MS lesions.
