Defining Large Core Infarction: Comparing the Accuracy of Non-Contrast CT ASPECTS Versus CT Perfusion Core Volume.

Key Points

• The study aims to evaluate the accuracy of non-contrast CT ASPECTS compared to CT perfusion in defining large core infarction.
• Examined LVO-AIS EVT-treated patients
• Compared classification of infarction size by non-contrast CT and CT perfusion
• Analyzed agreement in classifying small versus large core
• Both techniques showed slight agreement in infarction classification
• Neither non-contrast CT ASPECTS nor CT perfusion predicted future infarct volume (FIV) effectively
• No strong correlation with clinical outcomes observed
