Simple Standardized CT protocol Acute Stroke

Alberta stroke program early CT score

 

The Alberta stroke programe early CT score (ASPECTS) is a 10-point quantitative topographic CT scan score used in patients with middle cerebral artery (MCA) stroke. An ASPECTS score less than or equal to 7 predicts worse functional outcome at 3 months as well as symptomatic haemorrhage. According to study done by R.I AVIV etal patients with ASPECTS score <8  treated with thrombolysis did not have a good clinical outcome.
