1. A method of assisting a stenting procedure in a human or an animal, comprising the steps of: obtaining a first set of intracranial blood flow data from a patient; generating blood flow factor values from said first set of blood flow data, the blood flow factor values including at least a value for mean blood flow velocity and a value for systolic acceleration; correlating said blood flow factor values; assessing blood flow based upon said correlated blood flow factor values; and inserting a stent at a location within a lumen, the location being based upon the assessed blood flow.
