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.

ASPECTS Training Course and Certificate Info:

The educational modules (EdModules) will take you through basics of the clinical presentation, imaging, and initial assessment of acute stroke on CT scans with insights on how to determine early ischemic changes and the ASPECT Score. Subsequent modules will focus on multiphase CTA (mCTA)  and assessment of the collateral circulation

    Effect of age and baseline ASPECTS on outcomes in large-vessel occlusion stroke: results from the HERMES collaboration

    CONCLUSION: There was no multiplicative interaction of age and ASPECTS on clinical outcomes in EVT or control arm patients. Outcomes in patients ≥75 years with ASPECTS 0-5 were poor, irrespective of treatment. Further investigation to define the role of EVT and range of acceptable outcomes in this subgroup is warranted.

    Physician factors influencing endovascular treatment decisions in the management of unruptured intracranial aneurysms

    CONCLUSION: Although several predictors of endovascular treatment decision were identified, there seems to be a high degree of uncertainty when estimating rupture risks, treatment complications, and treatment success for endovascular UIA treatment. More data on the clinical course of UIAs with and without endovascular treatment is needed.

    Impact and prevention of errors in endovascular treatment of unruptured intracranial aneurysms

    CONCLUSION: Neurointerventionalists perceived both technical and cognitive errors to be important sources of complications in endovascular UIA treatment. Simulation training, a cultural change, higher acceptance of bail-out strategies and better standardization of procedures were perceived to be most effective in preventing these.
