Ever Fortune AI Co., Ltd.
EFAI PNXXR is a software workflow tool designed to aid the clinical assessment of adult (22 years of age or older). Posteroanterior (PA) view Chest X-Ray cases with features suggestive of pneumothorax in the medical care environment. EFAI PNXXR analyzes cases using an artificial intelligence algorithm to identify suspected findings. It makes case-level output available to a PACS/workstation for worklist prioritization or triage. EFAI PNXXR is not intended to direct attention to specific portions or anomalies of an image. Its results are not intended to be used on a stand-alone basis for clinical decision-making nor is it intended to rule out pneumothorax or otherwise preclude clinical assessment of X-Ray cases.
Clinical details
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Clinical-use display mirrors the best exact-submission purpose source because the reviewed FDA packet did not provide a more specific usable abstraction.
Intended-user text reported in the exact-submission ACR model card.
Patient-population text reported in the exact-submission ACR model card; institutional setting may still require vendor confirmation.
Conservative normalization of explicit wording in an exact-submission source.

Limitations and supported-acquisition details reported in the exact-submission ACR model card.
Regulatory identity
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Implementation
Use these fields to structure a vendor demo, security review, and implementation estimate.
Interoperability terms explicitly reported in the exact-submission ACR model card; interface versions and local compatibility still require confirmation.
Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.
Exact-release security controls, data retention, hosting boundaries, and scoped assurance documentation require vendor confirmation.
Current training prerequisites, competency checks, and support commitments for the exact configuration require vendor confirmation.
Current drift, quality, uptime, alert, escalation, and incident-response commitments for the exact configuration require vendor confirmation.

ACR AI Central provides an exact-submission model card for EFAI ChestSuite XR Pneumothorax Assessment System; FDA labeling remains controlling for clinical use, limitations, and performance.
exact submission · checked 2026-09-09Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.
Structured study metadata from the exact-submission ACR model card; this is not an independent evidence synthesis.
Model sensitivity reported by ACR AI Central. Review endpoint, threshold, study population, and tested version before comparison.
Model specificity reported by ACR AI Central. Review endpoint, threshold, study population, and tested version before comparison.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.
K221552
ACR AI Central summarizes the regulatory study; consult the exact FDA materials before comparative use.
Costs and setup
These are common procurement questions; unknown values remain visible until a source supports them.
No public price or quote for the exact K221552 configuration was established in this review.
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
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA and recall packets were prepared and identity matched, but no new clinical or performance claim was promoted in the conservative fallback. Existing exact-submission facts retain their original source status and applicability; candidate literature remains quarantined. Automated exact-name discovery found 0 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.
