If intravenous contrast is administered, intense enhancement of the basal nuclei can occur--either owing to infarction and breakdown of the blood-brain barrier or from visualisation of the collateral vessels coursing through them.
The coronary collateral vessels were graded according to the Rentrop scoring system: 0=no filling; 1=filling of the small side branches; 2=partial filling of the epicardial artery by collateral vessels; 3=complete filling of the epicardial artery by collateral vessels (13).
The most common abnormal finding is ureteric or pelvic notching due to extrinsic compression from collateral vessels.
The collateral circulation was based on the injection that best opacified the occluded vessel: 0=no visible filling of any collateral vessels, Milling of side branches of the artery to be perfused by collateral vessels without visualization of the epicardial segment, 2=partial filling of the epicardial segment by collateral vessels, and 3=complete filling of the epicardial segment by collateral vessels (14).
