ACA
The ACA is divided into three segments:
A1: origin from the ICA to the anterior communicating artery (ACOM).
A2: from ACOM to the origin of the callosomarginal artery
A3: distal to the origin of the callosomarginal artery

ACM
The MCA is divided into M1, M2, M3 and M4 segments:
M1:  from the origin to bifurcation/trifurcation (the limen insulae); also known as horizontal
segment
M2:  from bi (tri) furcation to origin of cortical branches (circular sulcus of insula); also known
as insular segment
M3: opercular branches (those within the sylvian fissure); also known as opercular segment
M4:  branches emerging from the sylvian fissure onto the convex surface of the hemisphere; also
known as cortical segment

ACP
The PCA is divided into four segments named P1 to P4:
P1: from it origin at the termination of the basilar artery to posterior communicating artery
(PCOM), within interpeduncular cistern.
P2: from the PCOM around the mid-brain, is within crural cistern and ambient cistern
P3: quadrigeminal segment (segment with the quadrigeminal cistern)
P4: cortical segment (e.g., calcarine artery, within the calcarine fissure)
