The abbreviations used are H: half dose, F: full dose, P: poor collateral circulation, G: good collateral circulation, N: no carotid or M1 stenosis, M: male, F: female, RIC: right internal carotid, RCC: right common carotid artery, LIC: left internal carotid, and M1: horizontal segment of the middle cerebral artery. Normal: the bilateral carotid system including M1 is normal.
