MRA vs CTA
My doct has ordered a repeat of the MRA of the brain and neck that I had 6 months ago, but this time with contrast (as opposed to non-contrast before).
My exam is for: continued features of intense, randomly eposodic positional CNS vertigo (per an oto-neurologist), chronic dull headache which is better in the morning, CONFUSION (moving objects become a mental blur and hurt my eyes and head till I just have to put my head in my heads and cut off my senses till I regain my composure).
My doc told me there was a new standard, the CT angiogram, but grumbled about radiation exposure, and he simply ordered the MRA with no further discussion. Perhaps I should call and ask him to change his mind if it would be better for detection of abnormalities?
1) Might the CTA may show better details in the smaller blood vessels than the MRA. Plus, the MRA before was negative (again, without contrast), so would CTA be better as a "different view" than that MRA. Also, I hear there is an MR study designed for the smaller blood vessels, is this true?
2) Are there any other tests that might be done to find out the cause for severe nausea, attacks of positional CNS type vertigo, constant headache as described above, borderline delirium/attacks of fear and anxiety?
BILI TOTAL, BILI INDIRECT, AND PROTEIN C, very slightly above the normal range, but doctor didn't show concern). ENG negative
Topomax, Inderal LA, Lexapro, and Verapamil have failed to help.
