Mapping of normal and abnormal cerebrospinal fluid flow/motion patterns using steady state free precession imaging.
In a comparative study more than 35 brain magnetic resonance imaging examinations were analyzed by mapping the CSF flow/motion pattern using the steady state free precession technique with two different flow sensitivity directions. Significant deviations from the normal pattern were seen in ventricular enlargements due to obstruction with no evidence of CSF flow/motion and in normal pressure hydrocephalus with complex flow pattern in lateral ventricles, suggesting a diagnostic potential for this fast imaging technique with sensitivity to very slow flow.
