The purpose of this work was to develop and test
multiband RF excitation to accelerate a fully phase
encoded (FPE) technique when multiple RF excitations are
required to excite a wide range of off-resonance near
metallic implants. The femoral head of a hip prosthesis
was placed in water and three separate scans were
performed with a single RF band, each centered at a
different RF offset (-4000, 0, +4000 Hz). The fourth
scan used the MB RF pulse to excite all three RF bands
simultaneously. This work demonstrates feasibility for
reducing scan time using MB excitation near metal with
FPE methods.
