Intended Use

The SIGNA™ Sprint 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 SIGNA™ Sprint 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.

Device Story

SIGNA™ Sprint is a 1.5T whole-body magnetic resonance scanner. It utilizes time-varying magnetic field gradients and RF transmissions to acquire signals from nuclei, transforming them into diagnostic images (axial, sagittal, coronal, oblique), spectra, and parametric maps. Operated by trained professionals in clinical settings, the system features a 70cm bore, superconducting magnet, and detachable patient table. It integrates AI-based software applications (AIRx™, AIR™ Recon DL, Sonic DL™) to assist in image reconstruction and acquisition. Physicians interpret the resulting images to assist in clinical diagnosis. The device benefits patients by providing high-resolution, high signal-to-noise ratio images with reduced scan times.

Clinical Evidence

No clinical studies were required. Substantial equivalence is supported by bench testing and the submission of sample clinical images demonstrating diagnostic image performance equivalent to the predicate device.

Technological Characteristics

1.5T superconducting magnet with zero boil-off cryostat; 70cm bore; gradient coil (65 mT/m peak amplitude, 200 T/m/s slew rate); embedded body coil; 1.5T AIR Posterior Array; NEMA DICOM compliant; flame retardant materials; ISO 10993-1 biocompatibility; IEC 60601-2-33 safety compliance.

Indications for Use

Indicated for diagnostic MR imaging of the entire body, including head, neck, TMJ, spine, breast, heart, abdomen, pelvis, joints, prostate, blood vessels, and musculoskeletal regions in patients requiring axial, sagittal, coronal, oblique, or spectroscopic imaging, parametric maps, or dynamic studies.

Regulatory Classification

Identification

Dear Xinyu Song:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

# Device Description:

SIGNA™ Sprint is a whole-body magnetic resonance scanner designed to support high resolution, high signal-to-noise ratio, and short scan time. The system uses a combination of time-varying magnet fields (Gradients) and RF transmissions to obtain information regarding the density and position of elements exhibiting magnetic resonance. The system can image in the sagittal, coronal, axial, oblique, and double oblique planes, using various pulse sequences, imaging techniques and reconstruction algorithms. The system features a 1.5T superconducting magnet with 70cm bore size. The system is designed to conform to NEMA DICOM standards (Digital Imaging and Communications in Medicine).

Key aspects of the system design:

- Uses the same magnet as a conventional whole-body 1.5T system, with integral active shielding and a zero boil-off cryostat.
- A gradient coil that achieves up to 65 mT/m peak gradient amplitude and 200 T/m/s peak slew rate.
- An embedded body coil that reduces thermal and enhance intra-bore visibility.
- A newly designed 1.5T AIR Posterior Array.
- A detachable patient table.
- A platform software with various PSD and applications, including the following AI features:

# Comparison of Indications for Use

The changes in technology do not impact the indications for use. The indications for use have not been changed, other than to reflect the SIGNA™ Sprint product name.

Therefore, the intended use is the same as the predicate device in accordance with the FDA's guidance document "The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)]", dated 28 July 2014.

# Technology

The SIGNA™ Sprint employs the same fundamental scientific technology as its predicate device.

SIGNA™ Sprint is built with a superconducting magnet, gradient, RF transmit architecture, RF receive chain and software application suite.

# Comparison of Technological Characteristics

Overall, the SIGNA™ Sprint employs the same fundamental scientific technology and operating principles as the predicate device and reference devices.

There are some differences in characteristics between the proposed device and the predicate/reference devices, as summarized below:

| Subsystem or Component | Predicate Device SIGNA™ Premier (K193282) | Proposed Device SIGNA™ Sprint | Comments |
| --- | --- | --- | --- |
| Magnet | 3.0T Superconducting Magnet with active shielding. | 1.5T Superconducting Magnet with active shielding. | The magnet has same technology with different magnet field strength, and minor modification on enclosure. It is identical with Reference Device SIGNA™ Artist. |
| Gradient Subsystem | A gradient coil with water-cooled, active-shielded design. | | The gradient coil is modified to reduced DC resistance and AC impedance for less cooling requirements. |
| RF Transmit Subsystem | 3.0T Transmit with embedded body coil and local T/R coil. | 1.5T Transmit with embedded body coil and local T/R coil. | The platform body coil is modified to reduce thermal and enhance intra-bore visibility. The RF Transmit Subsystem except body coil is identical with Reference Device SIGNA™ Artist. |
| RF Receive Subsystem | 3.0T Digitize-Per-Pin (DPP) receive chain architecture. | 1.5T Digitize-Per-Pin (DPP) receive chain architecture. | The RF Receive Subsystem uses the same technology with different RF frequency. It is identical with Reference Device SIGNA™ Artist. |
