Role of CT imaging in acute stroke

faststroke with strokesens*

Fully automated processing platform for CT ischemic stroke studies

  • 0-click workflow:
    Background processing of Non-Contrast, CTA, mCTA and Perfusion series

  • Automated email3
    generated once background processing has completed


  • Automatic synchronization
    of all phases from multiphase CTA (mCTA)


Seamless integration to Circle Neurovascular's StrokeSENS* AI-based processing tools.

  • StrokeSENS ASPECTS1,2

    Based on the Alberta Stroke Program Early CT Score (ASPECTS), StrokeSENS ASPECTS uses validated machine-learning algorithms to automatically identify regions of the brain affected by early ischemic changes to aid physicians in assessment of the severity and extent of stroke damage.

    • Extract more from simple non-contrast CT
    • Automated scoring system augments physician assessment
  • StrokeSENS LVO1

    StrokeSENS LVO uses AI to identify Large Vessel Occlusion (LVO) on CT Angiography. StrokeSENS LVO automatically notifies the stroke team of suspected LVO cases within minutes of receiving the CTA image, supporting early engagement of the stroke team. In the case a LVO is detected, Suspected LVO is written onto the input DICOM image (CTA or 1st phase of mCTA) and results are automatically included in the email notification, helping notify the stroke team of the time-sensitive case.

Automate the work up of ischemic stroke cases with the FastStroke automated workflow

    • 0-click workflow: Background processing of ASPECTS1,2, LVO1 detection, mCTA and Perfusion6 series
    • Auto send preprocessed images and functional maps in email format to stroke team3

Comprehensive workflow solution for reviewing stroke workup images

  • Non-Contrast CT

    Review the non-contrast head CT, automatically displayed in standard reformatted planes.
    Includes StrokeSENS’ Automated ASPECTS1,2.

  • CT Angio

    Automatically displays CTA images in a thick 2D MIP with optimized WW/WL settings.
    Includes StrokeSENS’ Automated LVO detection and notification1.

  • Collaterals

    Smartly adapts to your scan practices synchronizing up to 6 multi-phase CTA passes to dynamically evaluate collateral circulation.

  • ColorViz

    Displays a sophisticated fused view using color visualization to help assess vascular enhancement timing.

  • CT Perfusion6

    Automated perfusion processing to generate functional maps.

  • Tissue Classification

    Automated brain symmetry of the midline & Deep Learning brain ventricle segmentation7. Identify/segment areas of modified perfusion.

  • Automated email generation3

    Share results with the stroke team immediately once background processing has completed.
