Figure 5.

This picture denotes the use of mathematical model #2 (MM2). The long axis of the distal A1 segment that was closest to the long axis of the aneurysm was determined as the dominant inflow. In this picture, the long axis of the aneurysm and the left A1 segment are in the same trajectory, creating a 180-degree angle. The A1 segment that was closest to 180 degrees to the long axis of the aneurysm was deemed the dominant inflow artery. In this case, the left A1 is determined as the dominant inflow artery.
