[Computed tomography of brain infarct with special reference to vascular territories and collateral pathways]

The essential approach to CT diagnosis is to evaluate precise radiological findings. However, in some cases, other additional information may play an important role in the detection of disease itself. In brain infarct, this can include clinical symptoms, the hemodynamics of cerebral circulation, and other factors. From this point of view, the normal vascular territories of the brain and collateral pathways in cerebral stenotic or occlusive vascular diseases are described, and representative cases are presented.
