Acceleration Technique Comment
  • Reduce number of slices acquired per breath-hold
  • Increases overall scan time
  • Reduce number of phases for each breath-hold:
    • by reducing acquisition matrix (scan or phase percentage)
    • by reducing FOV
    •
  • Reduces SNR
  • Increases spatial resolution
  • Increase voxel size
  • Decreases spatial resolution
  • Use parallel imaging
  • Prone to artefacts
  • Use respiratory navigator
  • Increases overall scan time
  • Acquire images in inspiration
  • Varying slice position with each breath-hold
  • Consider general anaesthesia
