Csf flow study chiari
WebPosterior fossa decompression is carried out to improve passage of cerebrospinal fluid (CSF) in patients with symptomatic Chiari 1 malformations (CM1), but the extent and means of decompression remains controversial. Dural opening with subsequent duraplasty may contribute to clinical outcome, but may also increase complication risk. http://radres.ucsd.edu/documents/Neuro/Neuro-MRI-Protocols.pdf

Webwith Chiari-like symptoms appear to have normal CSF flow on MRI. Some researchers have begun to use advanced techniques to actually quantify CSF flow in Chiari patients. However, the quantitative measurement of CSF flow is highly dependent on the exact technique used, resulting in different studies producing different results. WebMethods: Pre- and postoperative CSF flow dynamics were assessed by cine phase-contrast magnetic resonance imaging in 130 consecutive patients receiving posterior fossa decompression for a Chiari I malformation between 1997 and 2003. CSF flow was classified as "abnormal" if biphasic flow was either absent or decreased through the …
