ASPECT Score for

Assessment in Acute Stroke

  • Alberta Stroke Program Early CT score (ASPECTS) is a 10-point quantitative score used to assess early ischemic changes on non-contrast CT head.
  • ASPECTS is intended to provide a reliable and reproducible grading system on non-contrast CT examinations of the head for detection of early ischemic changes in patients suspected of having acute large vessel anterior circulation occlusion. It is used as part of the assessment for eligibility in receiving interventional mechanical thrombectomy treatment.
  • ASPECTS score is a simple and reliable tool for detection of early ischemic changes on non-contrast CT scans of the brain.

Based on the Plain/Non-contrast CT Head. The ASPECT Score can be used to assess early ischemic changes in acute stroke on any modern CT scanner without the need for additional processing steps making it easily applicable in many settings worldwide.

Imaging Based

Imaging Based

As the initial imaging modality to both screen for and establish the diagnosis of acute stroke, the ASPECT Score provides an opportunity to quantify the degree of ischemic changes in the brain parenchyma and serve as the basis for subsequent decision making.

A score out of 10, the ASPECT Score is an easy and widely understood means of communicating the extent of ischemic changes amongst care teams and physicians.

Data Driven

Data Driven

The score was developed in consideration of a multitude of imaging data of patients who presented with symptoms of acute stroke with proven vascular occlusion. The scale is used in clinical trials worldwide to quantify and classify the extent of early ischemic changes on a quantitative scale. 

Backed by Research

    Management and outcome of patients with acute ischemic stroke and tandem carotid occlusion in the ESCAPE-NA1 trial

    CONCLUSIONS: Tandem cervical carotid occlusion in patients with acute large vessel stroke did not lower the odds of good functional outcome in our study. Functional outcomes were similar irrespective of the management of the cervical ICA occlusion (stenting vs not stenting).

    Factors influencing thrombectomy decision making for primary medium vessel occlusion stroke

    CONCLUSIONS: Most physicians in this survey were interventionalists and would treat patients with MeVO stroke immediately with EVT. This finding supports the need for robust clinical evidence.

    Clinical impact of EVT with failed reperfusion in patients with acute ischemic stroke: results from the ESCAPE and ESCAPE-NA1 trials

    CONCLUSION: Clinical outcomes of EVT patients with failed reperfusion did not differ significantly from patients treated with best medical management.

    Endovascular Treatment Decision Making in Patients with Low Baseline ASPECTS: Insights from UNMASK EVT, an International Multidisciplinary Study

    CONCLUSION: Most physicians decided to proceed with endovascular treatment despite low baseline ASPECTS, particularly in younger patients. This may have implications on the design and execution of low ASPECTS randomized trials.
