CINA-ASPECTS

Avicenna.AI

CADx assistance for assessment and characterization of brain tissue abnormalities and early ischemic injury in patients with known MCA or ICA occlusion, using ASPECTS regions and scoring to evaluate extent of disease during image interpretation.

Evidence status: each field shows source quality, applicability, and review date. Research pending, information not established in reviewed sources, and vendor documentation pending are distinct outcomes.

Clinical fit

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose
CADx assistance for assessment and characterization of brain tissue abnormalities and early ischemic injury in patients with known MCA or ICA occlusion, using ASPECTS regions and scoring to evaluate extent of disease during image interpretation.
FDA source Exact FDA submission Checked 2026-09-09
Intended users
Neuroradiologists and clinicians, including stroke neurologists, general radiologists, neurointensivists, and vascular neurologists.
FDA source Exact FDA submission Checked 2026-09-09
Care setting and population
Clinical or hospital environment operating in parallel with standard care.
FDA source Exact FDA submission Checked 2026-09-09
Workflow role
Post-acquisition NCCT preprocessing, tilt correction, predefined-ROI analysis, and automatic ASPECTS scoring; the clinician confirms the occlusion prerequisite, reviews and edits the result, and archives the final output.
FDA source Exact FDA submission Checked 2026-09-09
Required input
Non-contrast head CT images in DICOM-compatible clinical imaging workflow from patients over 21 with known unilateral MCA or ICA occlusion, within 12 hours from time last known well, acquired on Canon, GE, Philips, or Siemens scanners; the clinician must confirm the LVO condition before results are available.
FDA source Exact FDA submission Checked 2026-09-09
Output and human action
An automatic ASPECTS score reflecting the number of affected regions, delineated and highlighted ASPECTS ROIs, a heat map of contributing voxels, region labels, underlying voxel values, and DICOM output for PACS or workstation review; the clinician can adjust the score.
FDA source Exact FDA submission Checked 2026-09-09
Limitations
Not intended for primary CT interpretation. It is validated and intended for known unilateral MCA or ICA occlusion, brain ischemia within 12 hours from last known well, patients over 21, and the listed Canon, GE, Philips, and Siemens scanner families. It is not suitable for tumors, abscesses, traumatic brain injury, hemorrhagic transformation, or hematoma; excessive motion, streak artifact, or significant noise can make scans technically inadequate.

Regulatory identity

FDA record and catalog context

The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
A standalone executable can run from the command line or through medical image communications devices; it does not interface directly with CT scanners or data-collection equipment. Results are stored in DICOM for transfer to PACS or a workstation, with exact interface versions and local compatibility not established.

Deployment and data flow
On-premise
Public source Exact FDA submission Checked 2026-08-13

Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.

Security and privacy
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-09

Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.

Training and support
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-09

Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.

Monitoring and change control
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-09

Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.

Evidence summary
FDA standalone testing used a retrospective, multicenter, multinational, multi-vendor, blinded study of CINA-ASPECTS v1.5 with 200 anonymized NCCT cases from five sites in the US and France, four scanner makers, and 27 models; the dataset was separated from training/testing data. The MRMC study used eight readers, four expert neuroradiologists and four non-experts, each scoring 10 regions in the 200 cases. Readers agreed with almost one-half region more per scan with the device, 4.1% (95% CI 3.3%-4.9%); overall reader ROC AUC improved from 0.75 unaided to 0.79 aided, and mean time per case decreased. These are reader agreement, reader ROC, and workflow-time endpoints, not device sensitivity or specificity.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA scope controls clinical claims. ACR provides bounded exact-submission catalog context. Candidate literature metadata remains a discovery queue until full-text identity, endpoint, population, and version review is completed. Automated exact-name discovery found 1 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
