Modelling Motion-Induced Signal Corruption in Steady-State Diffusion MRI.

Key Points

• The aim is to model how motion affects the diffusion-weighted steady-state free precession (DW-SSFP) MRI signals.
• Developed a model to capture the temporal evolution of DW-SSFP signals
• Estimated subject motion retrospectively using the model
• Provided open-source software for motion correction and analysis
• Successfully estimated subject motion using the developed model
• Reconstructed motion-corrected DW-SSFP data
• Facilitated future studies on the effects of subject motion during MRI acquisitions
