I saw a neurologist today cause ive had headaches for months, already had an mri and sinus cat scan, hes going to send me for a brain scan, hes checking for aneurism, can a brain scan catch what an mri couldnt, is a brain scan a cat scan? will it hel?

Actually “brain scan” is a sort of generic term that could be used to describe ct, mri, functional mri, eeg, etc. It’s not common to have headache from an aneurysm that didn’t bleed (but not impossible), and bleeding should have been seen with ct or mri. For aneurysm’s ct Angiogram, mr angio or traditional angio’s show blood vessels best! remember most headaches won’t show physical abnormality

Am perplexed, as if this is a traditional brain scan, there is no true accuracy or reliability as compared to CAT or MRI, and most neurology practices would never order this archaic study. If there needs to be more precise vascular studies, a CTA or MRA would be the choices.
