EFAI Neurosuite CT Midline Shift Assessment System (MLS-CT-100)

Ever Fortune.AI, Co., Ltd.

Authorized purpose: Prioritization and triage of non-contrast head CT cases with features suggestive of midline shift in individuals aged 18 years and older.

Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

Overview status: Source-reviewed overview

Clinical takeaway

Clinical role: Prioritization and triage of non-contrast head CT cases with features suggestive of midline shift in individuals aged 18 years and older.

Evidence takeaway

Evidence from the reviewed source record: FDA retrospective, blinded, multisite validation used 300 US cases (102 positive and 198 negative) with majority ground truth from three US board-certified radiologists. The dataset included multiple CT manufacturers and a mean age of 59.46 years. Standalone sensitivity was 0.961 (95% CI: 0.903-0.985), specificity was 0.955 (95% CI: 0.916-0.973), AUROC was 0.983 (95% CI: 0.967-0.996), and mean processing time was 62.04 seconds (95% CI: 60.65-63.44); subgroup analyses were also performed.

Output and human action
Case-level passive notification available to a PACS/workstation for worklist prioritization when suspected MLS is identified; no preview image or marking of a specific location is provided.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-09
Limitations
The device is limited to non-contrast head CT and suspected MLS in individuals aged 18 and older, with no user control to select other findings. Results are not for standalone clinical decision-making and are not intended to rule out MLS or preclude clinical assessment. The packet describes on-premise deployment without cloud-server interfacing.

Implementation

Questions for IT, informatics, and operations

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

Integration
The device sends case-level notification to a PACS/RIS workstation for worklist prioritization and is deployed only on-premise; the packet states that it does not interface with cloud servers and does not establish a specific local interface or protocol.
