This study introduces velocity-selective perturbation using radiofrequency (RF) pulse trains for magnetic resonance imaging (MRI). This technique allows for the selective manipulation of both flowing and stationary spins, enhancing imaging capabilities.

Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Biomedical Engineering
  • Physics

Background:

  • Radiofrequency (RF) pulse trains are established for chemical shift selective perturbation.
  • Velocity-selective perturbation offers analogous control over spin behavior.
  • Biomedical application requires specific RF pulse train designs for viability.

Purpose of the Study:

  • To propose and examine the incorporation of velocity-encoding gradient pulses into RF pulse trains.
  • To investigate the principles and potential of velocity-selective perturbation in MRI.
  • To develop and evaluate new RF pulse sequences for selective spin manipulation.

Main Methods:

  • Incorporation of velocity-encoding gradient pulses within RF pulse trains.
  • Inclusion of RF refocusing pulses to ensure viability in biomedical settings.
