State-of-the-art imaging solution provides automated scoring to assess early signs of brain ischemia
Gothenburg, Sweden - May 15, 2018 - At the European Stroke Organization Conference, iSchemaView publicly launched RAPID ASPECTS, a digital imaging solution designed to help clinicians assess early signs of brain ischemia in stroke.
RAPID ASPECTS automatically generates a standardized score and provides visualization of individual ASPECTS regions so clinicians can review the automated result. At the time of the announcement, RAPID ASPECTS was CE-marked for use in Europe.
The Alberta Stroke Program Early CT Score (ASPECTS) is a manual 10-point scoring system based on subtle changes seen on non-contrast CT. The release noted that scoring can vary between readers, including experienced stroke imaging specialists.
Dr. Benjamin Friedrich said automated scoring could be particularly useful for primary stroke centers with smaller case volumes. Greg Albers, Professor of Neurology at Stanford University, Director of the Stanford Stroke Center and cofounder of iSchemaView, highlighted the role of ASPECTS in treatment decisions. The 2018 American Heart Association/American Stroke Association guidelines included ASPECTS among the criteria used for mechanical thrombectomy in selected patients treated within six hours of symptom onset.
How RAPID ASPECTS works
RAPID ASPECTS receives data from standard CT scanners, aligns the images and identifies the ASPECTS regions. A confidence control allows clinicians to review suspicious regions and determine a final score.
The release also described the following features:
- Slice navigation, zoom and window controls for evaluating regions of interest
- Manual score adjustment by adding or subtracting regions
- One-click return to the fully-automated score
Don Listwin, then CEO of iSchemaView, described RAPID ASPECTS as a tool for more consistent ASPECT scoring and easier communication between care teams and referral centers.
Key presentations at ESOC
The release also highlighted ESOC presentations involving iSchemaView cofounder Dr. Greg Albers, including sessions on DEFUSE 3 and late-window thrombectomy selection, as well as a presentation by Dr. Benjamin Friedrich on the clinical feasibility and reliability of automated ASPECTS scoring.
