This work describes an enhancement of the gapped SWIFT (SWeep
Imaging with Fourier Transformation) method utilizing
multiple sidebands to achieve highly increased
excitation and acquisition bandwidth. The method is
called Multi-Band-SWIFT (or MB-SWIFT). Due to its
tailored (striped) excitation pattern, MB-SWIFT
efficiently uses transmitter power and has increased
sensitivity as compared to the other techniques used for
ultrashort TE imaging. Additionally, MB-SWIFT provides
a way to obtain additional information about fast and
slow relaxing spins in a single scan. These features
make MB-SWIFT an attractive method for numerous MRI
applications including musculoskeletal imaging.
