The Radiologist's AI Playbook: How Radiologists & Group Leaders Integrate FDA-Cleared CADe/CADx Without Surrendering Liability Defense

The CADe vendor said it would speed up your reading list. It did. Now your medical director is asking why your peer review rate is unchanged. FDA-cleared CADe and CADx tools are everywhere. The clinical evidence is mixed, the workflow integration patterns vary wildly between groups, and the liability picture is unsettled — the courts are still working out who is responsible when AI flags something the radiologist missed (or vice versa). This Playbook is for the practicing radiologist or group leader who wants the productivity gains and the liability framework, in one place, organized by modality. Inside: FDA-cleared CADe/CADx vendor due diligence — 510(k) summaries, training-population disclosures (verifiable); marketing performance claims (treat as marketing) Modality-specific workflow protocols: chest X-ray, mammography, CT lung, brain MRI Second-read vs. concurrent-read decision frameworks (with malpractice implications of each) Billing and CPT coding for AI-assisted reads (where reimbursement exists, where it doesn't) Peer review templates that capture AI use without creating discoverable problems Malpractice defense documentation: what to keep, how long, in what form Group-level AI governance: vendor selection, performance monitoring, incident response Written for: Practicing radiologists, radiology group leaders, imaging informatics directors, quality officers in radiology departments, and radiology malpractice defense counsel preparing AI-touched cases.
