Key Points

  • To assess the effectiveness of diffusion weighted fast spin echo on portable low-field MRI systems.
  • Utilized diffusion weighted fast spin echo technique.
  • Employed multiband quadratic phase increment for data acquisition.
  • Focused on low specific absorption rate (SAR) and higher peak B1.
  • Achieved high signal-to-noise ratio (SNR) efficiency in low-field conditions.
  • Demonstrated robustness and reduction in image distortion compared to traditional methods.

Abstract

Diffusion weighted FSE is a robust, distortionless approach for high SNR efficiency DWI on portable MRI systems. Multiband quadratic phase increment DW-FSE leverages the low SAR and higher peak B1 provided by low field strengths and is less dependent on performant hardware compared to DW-EPI.
