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.

Implication

Multiband quadratic phase increment imaging shows high SNR efficiency in portable low-field MRI systems, suggesting improved diagnostic potential.

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.
