CTA (1)
  • This is the aortic arch[…]

CTA (2)
  • These are the 3 great vessels (R brachiocephalic, L CCA, L Subclavian)[…]

CTA (3)
  • These are the 3 great vessels (R brachiocephalic, L CCA, L Subclavian)[…]

    • red: CCA[…]
    • green: Verts[…]

CTA (8)
  • this shows the:
    • ECAs[…] (red, anterior) and ICAs[…] (green, posterior) at the level of the carotid bifurcation[…]

    • green: PCA[…] branching off the basilar[…]

CTA (12)
  • this shows the: 
    • red: supraclinoid ICA (C5 segment)[…] becoming the ophthalmic ICA (C6 segment)[…] after giving off the ophthalmic[…] artery briefly before turning around posteriorly
    • green: PCA[…]

CTA (17)
  • this first branch off the vert (intracranial segment)[…] (red) is the PICA[…] (green)

CTA (18)
  • this 2nd branch off the vert (intracranial segment)[…] (red) or first branch off the basilar[…] (not in this case) is the AICA[…] (green)

CTA (19)

CTA (21)
  • the vessel connecting the ICA[…] (green) to the PCA[…] (blue) is the Pcomm[…] (red)

Basilar artery fenestration[…] is the most common congenital anomaly of the basilar[…] artery, resulting from failed fusion of paired longitudinal neural[…] arteries, and may be associated with vertebrobasilar junction aneurysms[…]
MIP stands for Maximum Intensity Projection[…] reconstructed image (recontructs the 2D w/multiple slices > into 3D slabs) and is very helpful for a 1st-pass view to rule out LVOs before confirming on the source[…] images; slice thickness[…] shown in bottom left (here it's 10mm)
