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.

Easily Applicable

Easily Applicable

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. 

Easily Communicated

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.

    Patient-Relevant Deficits Dictate Endovascular Thrombectomy Decision-Making in Patients with Low NIHSS Scores with Medium-Vessel Occlusion Stroke

    CONCLUSIONS: The presence of a patient-relevant deficit in low-NIHSS acute ischemic stroke due to medium-vessel occlusion is an important factor for endovascular treatment decision-making. This may have relevance for the conduct and interpretation of low-NIHSS endovascular treatment in randomized trials.

    Influence of intravenous alteplase on endovascular treatment decision-making in acute ischemic stroke due to primary medium-vessel occlusion: a case-based survey study

    CONCLUSIONS: Intravenous alteplase is an important factor in EVT decision-making for MeVO stroke. However, even in alteplase-treated patients, more than half of the physicians decided to proceed with EVT without waiting for alteplase effect.

    A Detailed Analysis of Infarct Patterns and Volumes at 24-hour Noncontrast CT and Diffusion-weighted MRI in Acute Ischemic Stroke Due to Large Vessel Occlusion: Results from the ESCAPE-NA1 Trial

    Background The effect of infarct pattern on functional outcome in acute ischemic stroke is incompletely understood. Purpose To investigate the association of qualitative and quantitative infarct variables at 24-hour follow-up noncontrast CT and diffusion-weighted MRI with 90-day clinical outcome. Materials and Methods The Safety and Efficacy of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke, or ESCAPE-NA1, randomized controlled trial enrolled patients with...

    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).
