From: Robust Segmentation of the Full Cerebral Vasculature in 4D CT of Suspected Stroke Patients
Coronal view of a temporal maximum intensity projection visualizing part of the middle cerebral artery including the M1, M2 and M3 segments. Intensity differences from proximal to distal in a nonaffected vessel can reach up to 450 HU and higher. Vessel occlusions, vessel wall calcifications, collateral flow, clip and stent artifacts have a large influence on the continuity of intensity values along the vessel.
