e-ASPECTS is an image processing software that provides both analysis and viewing capabilities for brain CT datasets of stroke patients for detection of changes in the image related to stroke and calculation of the extent of these changes (such as ASPECTS, the Alberta Stroke Program Early CT Score), and visualization of these changes.¹

Images shown for illustrative purposes only.

Brainomix 360 is a comprehensive platform designed to support clinicians and their imaging-based treatment decisions at all points across the stroke pathway, from simple imaging to more advanced imaging.

The Brainomix 360 Mobile App allows clinicians to quickly and securely access, preview, and share images and patient data across a network, send messages, make calls, and enhance collaboration for patient care - all designed to optimize workflow, facilitating faster transfer and treatment decisions.²

Scanning Parameters

Slice thickness: 2mm maximum slice thickness
Acquisition volume: Single cerebrum sequence from circle of Willis level or below, up to the vertex
Reconstruction method: Filtered back projection (FBP) with a moderate filter kernel (i.e. no excessive sharpening or smoothing). Iterative reconstruction methods with small kernel size (not too much smoothing) may also work but will need testing on site.
Window: Brain window (not bone window)

AI Output

ASPECT score
Acute / non-acute hyperdensity volume [ml]

Other Relevant Information

Currently not made available with Calantic Viewer. Separately distributed by Bayer.

EU risk class and CE marking
e-ASPECTS has CE marking and risk class IIa.

Reimbursement status
Not reimbursed.

Contraindications
e-ASPECTS is not suitable for use on brain scans displaying neurological pathologies other than acute stroke, such as tumors or abscesses.

Target Population
Patients over 21 years old.

Limitations

e-ASPECTS should not be used as a standalone diagnosis. It should only be used by a competent stroke physician or neuroradiologist with an understanding of brain CT image interpretation, as an aid to image interpretation.
e-ASPECTS may not detect all chronic (old) infarcts, or may incorrectly classify them as fresh ischemic damage.
e-ASPECTS will not correctly identify early ischemic changes in every scan, and may generate false positives or false negatives in any region. The user should use their own expertise in CT image analysis to verify that the software's output is correct.
e-ASPECTS may not detect all abnormal hyperdensities, or may incorrectly highlight areas of the image that are not abnormal hyperdensities.
The performance of e-ASPECTS is limited by the quality of the input CT image. The user should therefore manually inspect the image for scanner artifacts and poor quality images to avoid incorrect results.
The user of e-ASPECTS should verify that the software's segmentation is correct, by inspecting the CT image annotations of ASPECTS regions, before using the results.
