Hippocampal cerebrospinal fluid spaces on MR imaging: Relationship to aging and Alzheimer disease
Magnetic Resonance Imaging
Identifying hippocampal atrophy (enlarged PHF) may be particularly challenging in the presence of HSC. Distinguishing among the CSF spaces in hippocampus may help in the radiologic evaluation of hippocampal atrophy. Patients with extremely high HSCs (>8.4) can be excluded from AD risk with 93% specificity.
