This study predicts tracer distribution in the brain using geometric MRI data, showing strong correlation with actual tracer enrichment in patients with similar diagnoses.

The paper tests numerical methods for reconstructing cerebrospinal fluid flow from contrast-enhanced MRI data, finding that methods perform well in idealized settings but struggle with patient-specific data.

The paper models CSF circulation to show that convection in the subarachnoid space rapidly clears tracers from intracranial compartments, reducing clearance time from years to days compared to diffusion.
