ASPECTS
Also written as: ASPECTS — Alberta Stroke Program Early CT Score
Alberta Stroke Program Early CT Score, a systematic method for quantifying early ischemic changes on non-contrast CT in acute stroke.
Full Definition
The Alberta Stroke Program Early CT Score (ASPECTS) is a standardized 10-point scoring system used to assess the extent of early ischemic changes in the middle cerebral artery territory on non-contrast CT. The scale divides the MCA territory into 10 regions, with 1 point subtracted for each region showing early ischemic changes such as loss of gray-white differentiation or tissue hypodensity. ASPECTS scores ≥7 are generally associated with better functional outcomes and lower risk of symptomatic hemorrhage following reperfusion therapy. This scoring system helps standardize stroke imaging interpretation and guides treatment decisions in acute stroke care.
Usage
Usage note: Always provide numerical score (e.g., ASPECTS 7/10) for clinical utility.
