OK someone please explain like I'm 5. When and why would I need a cerebral perfusion vs. angio? Both use contrast. Perfusion checks the collaterals that can still supply the injury. Does angio only check the large vessels? I just cant wrap my head around how the two are different and when I would need to order them!
