Time to go with the flow!
Knowing vascular anatomy is the first step to reading any angiogram
These are the key vessels you need to know!
Then I always remember to check for pathology using the mnemonic ANGIO to remind me what to look for:
A = aneurysms, arteriovenous malformations
N = Narrowing (atherosclerotic narrowing)
G = Globules (globular or beaded appearance in vasculitis or RCVS)
I = Irregularity/dissction
O = Occlusion (large vessel occlusion for endovascular)
So now you know the anatomy & pathology to look for angiographic studies!
Hopefully, now you will never have to circle back on a study of the circle of Willis!!
