## Recalls of this device
- Jun 14, 2024 · Class II · Z-2460-2024: GE HealthCare has become aware that for certain MR systems, the system predicted B1+RMS value can exceed the B1+RMS user prescribed limit when scanning in Low SAR Mode and the following two conditions
- Dec 23, 2021 · Class II · Z-0592-2022: The magnetic resonance systems could potentially have a cryogen ventilation system that does not meet the venting requirements.
- Aug 26, 2021 · Class II · Z-0134-2022: Under certain conditions, some slices may be missing which can lead to a gap of anatomy in the 3D Volume images.
- Jun 4, 2021 · Class II · Z-2054-2021: GE Healthcare has recently become aware of an issue on the affected products listed below where the "Patient Orientation" button may inadvertently be clicked when intending to click on the "Save RX" b
- Dec 23, 2019 · Class II · Z-0876-2020: It was identified that due to a potential installation workflow issue, the MR system date could be set incorrectly. The system's date and time setting are used to populate the DICOM header information
- Mar 1, 2016 · Class II · Z-1347-2016: Ferrous material in the SIGNA Pioneer Table Control Box (TCB) could cause unexpected attraction to the MR system's high strength magnetic field during servicing activities. This could create a potenti

## Indications for use
The SIGNA Pioneer is a whole body magnetic resonance scanner designed to support high resolution, high signal-to-noise ratio, and short scan times. It is indicated for use as a diagnostic imaging device to produce axial, sagittal, coronal, and oblique images, spectroscopic images, parametric maps, and/or spectra, dynamic images of the structures and/or functions of the entire body, including, but not limited to, head, neck, TMJ, spine, breast, heart, abdomen, pelvis, joints, prostate, blood vessels, and musculoskeletal regions of the body. Depending on the region of interest being imaged, contrast agents may be used. The images produced by the SIGNA Pioneer reflect the spatial distribution or molecular environment of nuclei exhibiting magnetic resonance. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.
