Question: Flow voids - are they abnormal

 tiffairy - Sun Jan 21, 2007 7:10 pm

I just noticed that my most recent MRI showed "flow voids in the major intracranial vessels" yet the impression came back as normal other than a Chiari Malformation. Exactly what are flow voids?

User avatar This is a normal finding. Essentially, MRI can not see moving blood and the blood vessels look empty (thus the term flow void). Do not worry about.

Good luck
