摘要:
Systems, methods, and other embodiments associated with steady state dark blood magnetic resonance imaging MRI are described. One example method includes controlling an MRI apparatus to produce a steady state pulse sequence. The example method may also include controlling the MRI apparatus to generate radio frequency (RF) energy and magnetic gradients associated with the steady state pulse sequence. The steady state pulse sequence is different from conventional steady state pulses in that it is characterized by regularly spaced slice selection excitation pulses to excite a region to be imaged in an object to be imaged using a consistent repetition time (TR), a set of readout modules, and a set of a magnetization preparation modules. A magnetization preparation module is characterized by gradients associated with imaging not being active, gradients associated with slice selection being active, and RF pulses associated with slice selection being active.
