FDA-cleared profile
Siemens Medical Solutions USA, Inc.
AI-Rad Companion Pulmonary processes CT DICOM studies to support lung and lobe segmentation, measurements, density thresholds, and pulmonary-lesion segmentation, measurement, and lobe assignment.
Clinical fit
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
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.
This is the interface boundary described in the exact FDA package; current local compatibility, routing, identity, archive, and downtime behavior still require acceptance testing.
The exact public FDA decision material does not establish the complete deployment topology, hosting responsibility, availability, upgrade path, or service contract.
Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.
Monitoring guidance is buyer-facing implementation guidance derived from the exact cleared scope; it is not a claim that the FDA package provides a live monitoring service.
Map installed model, build, options, population, anatomy, inputs, outputs, and enabled functions to K183271 before acceptance.

The exact public deployment topology remains incomplete; establish hosting responsibility, data flow, availability, upgrade, service, and downtime boundaries locally.
exact submission · checked 2026-09-04FDA-described deployment boundaries do not establish current hosting contracts, security controls, uptime, or local qualification.
The FDA package describes processing of CT DICOM studies; exact local routing, archive, and output behavior remain unverified.
exact submission · checked 2026-09-04Test representative identifiers, orientation, geometry, measurements, units, routing, failure handling, and round trips locally.
Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. The FDA validation scope is adult CT DICOM data with specified scanner and reconstruction conditions; lung and lesion outputs require professional review.

Model capital and recurring cost against net staff time after review, throughput, repeat imaging or rework, room time, consumables, infrastructure, training, service, downtime, upgrade, and replacement costs.
product family · checked 2026-09-04No exact-product price was found in the reviewed public material; productivity or value claims require local evidence.
Monitor K183271 by exact hardware, software, model, and algorithm version; patient population; anatomy; protocol; operator; input quality; output edits or overrides; failed studies; repeat acquisition or rework; downstream impact; downtime; incidents; recalls; and updates. Track these product-specific limits: The FDA validation scope is adult CT DICOM data with specified scanner and reconstruction conditions; lung and lesion outputs require professional review.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.
Sensitivity is not promoted as a product-wide endpoint. Compare only an exact endpoint, threshold, population, version, and source if later verified.
Specificity is not promoted as a product-wide endpoint. Compare only an exact endpoint, threshold, population, version, and source if later verified.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.

Manufacturer evidence submitted for the exact FDA decision. It is not independent clinical validation, and local technical, clinical, privacy, security, and workflow acceptance remains necessary.
Economics and lifecycle
These are common procurement questions; unknown values remain visible until a source supports them.
No public list price for the exact cleared configuration was found. Obtain a written quote separating hardware or license basis, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.
No separate named-product payment identified in reviewed public material
Centers for Medicare & Medicaid Services · United StatesThis is not a product-specific reimbursement determination. Build a local total-cost and value model and verify payer, site-of-service, coding, and coverage assumptions independently.
Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Exact-identifier review does not prove absence of all product-family safety signals.

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-name and exact-submission searches in the checked 2026-09-01 indexes returned 20 PubMed candidate records and 1 ClinicalTrials.gov candidate record for K183271; review status is candidate_review_pending. Literature and registry candidates remain quarantined unless exact submission and tested-version linkage is established. The checked recall disposition is no exact-submission recall record was promoted; ambiguous or family-only candidates are not published. Pricing, complete security architecture, contracted deployment, exact reimbursement, and local interoperability remain unverified. Automated exact-name discovery found 20 PubMed and 1 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.
