How useful is an MRA?

Hi everyone,

Contrast dye concerns aside, how useful is an MRA for assessing both arterial compression and also the distances of the styloids to the vessels?

I can see here a few people have had one done, so for what reason is a CTA the imaging modality of choice over an MRA/MRV?

Thanks!

CTs show the styloids much better as they’re bony, so that’s why a contrast CT is usually chosen. I guess that MRAs have maybe been done if there’s a suspicion of something other than ES going on?
