ColorViz - Pseudoocclusion

Color-coded mCTA summation maps may facilitate easier assessment of acute stroke pathology!

Based on the 3 phases of the multiphase CTA, Color coded maps demonstrate the extent of delay in a vessel at high resolution.This case demonstrates a pseduo-occlusion of the carotid artery. 

 

Differentiation between an occluded and a patent extracranial internal carotid artery (ICA) is crucial in the diagnostic workup of patients with acute ischemic stroke; particularly in patients eligible for endovascular treatment.

Color-coded mCTA summation maps may facilitate easier assessment of acute stroke pathology, including better assessment of collateral status, distal occlusions, carotid pseudo-occlusions, intracranial stenosis, and thrombus permeability. ColorViz may be particularly useful for less experienced readers.
