A magnetization preparation sequence that efficiently
combines T2-Prep and outer volume suppression is
designed and tested for coronary angiography. The
proposed sequence is composed of a BIR-4 90 tip-down
pulse, two adiabatic refocusing pulses and a 2D spiral
90 tip-up pulse. Its performance is demonstrated with
numerical simulation, phantom and in vivo experiments.
This sequence induces T2 weighting to improve
blood-myocardium contrast while suppressing outer volume
signals to facilitate scan acceleration and reduce
motion artifacts.
