Automatic Identification of ASPECTS Regions and Scores

Based on the Alberta Stroke Program Early CT Score (ASPECTS), Rapid ASPECTS* uses validated machine-learning algorithms to automatically identify regions of the brain and generate scores to help physicians quickly assess patient eligibility for thrombectomy.

Standardized Results for Predictive Assessment of Patient Eligibility for Thrombectomy

Rapid ASPECTS automatically delivers standardized ASPECTS regions and scores to enable physicians to quickly identify areas of irreversible injury on non-contrast CT (NCCT) scans—helping stroke teams make faster triage-or-transfer decisions.

Rapid ASPECTS Output

Rapid ASPECTS receives CT scan data, tilt corrects images, identifies the ASPECTS regions, and provides an automatically generated measure of early ischemic change on non-contrast CT (NCCT) scans which predicts irreversible injury.


Rapid ASPECTS provides fast, simple viewing features including slice up and down, zoom, and windowing so physicians can evaluate regions of interest. Users also have the option to manually add or subtract regions to adjust the score.

Validated Machine Learning AI

Rapid ASPECTS results are automatically calculated using machine learning algorithms that have been validated in a number of clinical research studies. 


Faster Clinical Decisions for Better Patient Outcomes

  • Automatic. ASPECTS automatically delivers a standardized ASPECTS score to enable a physician to quickly identify areas of irreversible injury.
  • Validated. Rapid ASPECTS uses sophisticated, machine-learning algorithms that have been validated in a number of clinical research studies to deliver fast ASPECTS measurements.
  • Fast. Within minutes of receipt of an NCCT scan, Rapid ASPECTS delivers results via PACS, email, and the RapidAI mobile app to help stroke teams make faster clinical decisions for patients with large vessel occlusions (LVOs)—helping to facilitate better patient outcomes.

“In my opinion, using Rapid ASPECTS increases the likelihood of getting a reliable ASPECT score, independent of the individual skills and experience of the clinician. This tool is therefore particularly suitable for primary stroke centers with a smaller number of cases. Early and reliable information makes it possible to quickly understand the prognosis of a patient."
