Which type of Magnetic Resonance Angiography is usually used for the brain?
 

Hi all,
this post isn't directly related to TBI, but I'm assuming that some of you all have had magnetic resonance angiography performed to check for any potential issues with blood vessels in your brain. Apparently there are three broad types of magnetic resonance angiography- 'Time of Flight', 'Phase Contrast', and 'Contrast-Enhanced'; do you know which one is usually used to visualize blood vessels in the brain?

Please note: I've reposted this in other subforums (such as the traumatic brain injury subforum), in case no one replies in this one.

Many thanks in advance.
