RADIOLOGICAL METHODS AND METHODOLOGIES FOR ASSESSING COLLATERAL BLOOD CIRCULATION OF THE BRAIN

Collateral circulation is assigned a decisive role in the final outcome of ischemic stroke. Accordingly, the refinement of various methods and methodologies for assessing this system is becoming increasingly relevant. Currently, there are numerous radiological methods that allow us to assess not only the anatomy of collateral circulation but also to gain an understanding of its quantitative characteristics. Furthermore, the modern radiological literature publishes the latest studies comparing various methodologies for the qualitative and quantitative assessment of collateral circulation to determine which of them is more accurate and yielding better results.
