Question: abnormal gray and white matter attenuation

 medicalinquiries - Mon Mar 30, 2009 12:14 am

i suffered a concussion two months ago and had continued clumsiness. i had a ct scan last week to r/o a slow bleed, but none was found. the scan did indicate "abnormal gray and white matter attenuation." what does this mean, and is it related to the concussion, or could it be from something else? i am otherwise healthy.

User avatar Hi there --

Gray and white matter attenuation -- or attenuation of anything subject to imaging, is a matter of how the imaging procedure worked, more than what it disclosed or did not. While inability to get a normal or precise attenuation of some part of a target area can sometimes indicate a problem in the patient, it just as often suggests a problem with the imaging process itself. Sometimes it's unavoidable, and when it's not sometimes a radiologist will choose to disregard it and not re-do, if it's not especially relevant to a possible diagnosis. In your case this would seem to be the case: that the inability to visualise the gray and white matter fully wasn't particularly relevant to the study, but of course has to be noted on the report anyway, since it affects the reading of the films.

In short, I don't think this bears on your residual symptoms. I hope this is helpful, and please do follow up with us here as needed.
