Alberta Stroke Program Early CT Score (ASPECTS)
Please fill out required fields.
Using the traditional cutoff (<8 vs ≥8) as a rough estimate for predicting independence can inform decisions. Like the 1/3rd score, the ASPECTS points out that early CT changes in stroke may be a harbinger.
We are unaware of validated management algorithms using the ASPECTS.
The ASPECTS relies on subtle CT findings and thus requires an experienced radiologist. Its only validated use is as a binary (<8 vs ≥8) variable for general outcome prediction in those eligible for reperfusion therapy.
