Exploratory assessment of cerebrospinal fluid-related microdynamics after mild traumatic brain injury using intravoxel incoherent motion magnetic resonance imaging

Aim: -value-based CSF motion between patients with TBI and healthy controls. Methods: -values were evaluated, and longitudinal changes were assessed in three patients who underwent follow-up MRI. Results: -values in supratentorial regions over time-suggesting partial recovery-whereas infratentorial regions demonstrated decreasing or stable trajectories. Conclusion: Mild TBI may be associated with region-specific alterations in CSF microdynamics, characterized by increased motion in the CPA and exploratory reductions in selected supratentorial regions. Although preliminary, these findings highlight the potential of IVIM MRI as a complementary tool for investigating post-traumatic abnormalities in CSF motion.
