Who uses it?Intended users: Trained physicians for interpretation of the images and/or spectra.
What does the software produce?Output: Axial, sagittal, coronal, and oblique images; spectroscopic images, parametric maps and/or spectra; and dynamic images of structures and/or functions of the entire body, with AIR Recon DL improving signal-to-noise ratio and image sharpness.
What is its most important limitation?Key limitation: The images and/or spectra yield information that may assist in diagnosis when interpreted by a trained physician; depending on the region of interest, contrast agents may be used.
Clinical takeaway
Clinical role: SIGNA Premier is a 3.0T, 70 cm bore whole-body MRI system for diagnostic imaging across multiple anatomies; K193282 adds AIR Recon DL, a deep-learning reconstruction option intended to improve signal-to-noise ratio and image sharpness and enable shorter acquisitions while preserving those properties, with images and spectra interpreted by a trained physician.
Evidence takeaway
Evidence from the reviewed source record: Exact-submission FDA evidence includes manufacturer phantom, digital-object, in vivo, and blinded-reader testing, but public counts and patient outcomes are absent. A later 54-examination SIGNA Premier pediatric knee study found AIR Recon DL could materially change quantitative diffusion metrics at higher spatial resolution, and an independent 7,346-examination outpatient study found the AIR Recon DL group achieved up to a 27% scan-time reduction without a significant room-time reduction. These later studies are product-family evidence and do not establish exact K193282 performance at a new site.

A site still needs scanner-room planning, shielding and power review, MR safety zoning, coil and protocol configuration, PACS and RIS integration, acceptance testing, service coverage, and downtime procedures.
No exact K193282-era cybersecurity architecture, MDS2, supported operating-system inventory, patch policy, remote-service controls, audit specification, or vulnerability-management document was established from the reviewed public sources.
Training and support
The FDA-cleared workflow requires trained personnel and trained-physician interpretation. GE separately offers a 3.5-day classroom and lab course for biomedical engineers servicing SIGNA Premier systems; this is service training, not evidence of the clinical-user training package supplied with K193282 or of AIR Recon DL protocol competency.

Pricing and total cost
No public purchase price for the K193282 SIGNA Premier system or AIR Recon DL option was found. GE lists a separate 3.5-day advanced SIGNA Premier service course at $15,500 tuition only, $16,100 with lodging, or $17,600 with lodging and airfare; these amounts are implementation-cost benchmarks, not scanner, software, maintenance, or clinical-training prices.
CMS NCD 220.2 addresses coverage of medically necessary MRI and MRA services performed on FDA-authorized equipment within its labeling; it does not establish a separate payment for SIGNA Premier or AIR Recon DL. Coverage, coding, payment, and prior-authorization analysis remains examination-, payer-, site-, and patient-specific.

Postmarket safety review
FDA recall Z-1767-2026 includes SIGNA Premier systems that may contain ferrous steel fittings at the rear of the magnet instead of non-ferrous brass fittings, creating a personnel-injury risk if the rear is serviced while the magnet is ramped. FDA lists the recall as open and classified. FDA recall Z-2304-2025 includes SIGNA Premier systems for which planned maintenance may not have checked patient-table caster-lock function, allowing an undocked table to move during patient transfer. FDA lists the recall as open and classified. FDA recall Z-2462-2024 includes SIGNA Premier software RX27.0-RX27.3, RX28.0, RX29.0-RX29.2, MR30.0, and MR30.1. Under specified Low SAR and 2D T2 FLAIR settings, predicted B1+RMS can exceed the prescribed limit and overheat an MR-conditional implant. FDA lists the recall as open and classified. FDA recall Z-1430-2022 affects SIGNA Premier model 5748519 because rare gradient-coil conditions could produce elevated acoustic noise and prolonged exposure could lead to hearing loss. FDA lists the recall as open and classified. FDA recall Z-0590-2022 includes the superconducting magnet used in SIGNA Premier systems because the cryogen ventilation system may not meet venting requirements. FDA lists the recall as open and classified. FDA recall Z-0132-2022 affected SIGNA Premier because some slices could be missing under certain conditions, creating a gap in anatomy in three-dimensional volume images. FDA lists the recall as terminated. FDA recall Z-2052-2021 affected SIGNA Premier because a user intending to select Save RX could inadvertently select Patient Orientation before the initial three-plane localizer, potentially producing incorrectly annotated or flipped images. FDA lists the recall as open and classified.
