Application of blood suppressed 3D T2-weighted sequence to MR nerve imaging with uniform fat and water separation in a single acquisition is shown here. Fat/water separation is achieved by a modified 2-point Dixon reconstruction. Vessel suppression is achieved by the use of motion sensitized driven equilibrium (MSDE), inserted in front of a 3D FSE module, in combination with optimized use of variable refocusing flip angles for the acquisition. In addition, images with and without fat suppression from the same acquisition can give complementary information related to the nerves and surrounding tissues with perfect co-registration.
