Recalls attributed to this device

  • Recalling firm matches this device's applicant (Siemens Medical Solutions USA, Inc.) — same firm and product code, not necessarily this device · initiated 2023-07-12

    During a whole-body planar scan with auto-contour, there is a possibility the short-linear drive (SLD) look-ahead sensors may trigger earlier than expected and may result in detector 1 positioning further from the patient than needed leading to a reduction in image resolution.

  • Recalling firm matches this device's applicant (Siemens Medical Solutions USA, Inc.) — same firm and product code, not necessarily this device · initiated 2023-01-16

    This is a potential problem with the locking mechanism that is used to secure the PET gantry in either its scanning or service position.

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.
