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.

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
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
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
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
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.

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 category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
ACR AI Central provides an exact-submission model card for CINA-ASPECTS; FDA labeling remains controlling for clinical use, limitations, and performance.
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.

No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
Safety and lifecycle
Postmarket record
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Postmarket safety review
The exact-identifier FDA recall query returned no native recall record for K233342. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.

Verify security and privacy controls: Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
Verify training: Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
Verify pricing and total cost: No public price or quote for the exact K233342 configuration was established in this review.
Verify reimbursement and coding relevance: No exact-product payer policy, coding instruction, or payment determination was established; eligibility must be evaluated by payer, site of service, and use case.
Verify local validation and lifecycle monitoring: Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

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.
