CSF Flow

Quantitative phase contrast flow measurement has been utilized extensively to identify patients with normal pressure hydrocephalus (NPH).  Using the method of Bradley et.al. (1996) we quantify aqueductal stroke volume in comparison with scanner specific normative values.

CSF flow dynamics also provide a quantitative evaluation for alteration in CSF flow dynamics at the foramen magnum in patients with cerebellar tonsilar ectopia (Chiari I).
