Premarket evidence — what FDA accepted

Device typesamd
source quote (p.7)
Merge PACS, a software medical device, is a standards-based medical imaging diagnostic workstation that serves as an adjunct to assist the clinician to view, read, and report their findings. The software documentation was provided at a Moderate level of concern following the FDA's “Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices".
AlgorithmRegion Analysis Area and Region Analysis Volume tools for 2D and 3D SUV calculations; Automatic Registration for series that do not share a common frame of reference.
source quote (p.7)
The focus of this premarket notification is on the addition of the Region Analysis Area and Region Analysis Volume tools, which allows for additional clinical analysis of images, including volumetric Standard Uptake Value (SUV) calculation. Addition of Region Area and Volume Analysis tools allows for additional clinical analysis of PET images for patient treatment, including 3D SUV calculations. Automatic registration is through the functionality of Blackford to deliver DICOM objects to Merge PACS for automatic registration of series that do not share a common frame of reference.

Recalls attributed to this device

  • Recalling firm matches this device's applicant (Merge Healthcare, Inc.) — same firm and product code, not necessarily this device · initiated 2025-02-19

    When following a specific less typical workflow in which the user remeasures using the ultrasound device or manually edits primitive or derived measurement values directly in Clinical Reporting, derived measurements may be inconsistent with the associated primitive measurements in the final patient report.

    recall event 96344 (openFDA)

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
