Indications for Use
The SIGNA Hero 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 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, TMI, spine, abdomen, pelvis, joints, prostate, blood vessels, and musculoskeletal regions of the body.

| Device Trade<br>Name: | SIGNA™ Hero |
| Common/Usual<br>Name: | Magnetic Resonance Diagnostic Device |
| Classification<br>Names: | Magnetic Resonance Diagnostic Device per 21 CFR 892.1000 |
| Product Code: | LNH, LNI |
| Predicate<br>Device(s): | SIGNA™ Pioneer (K160621) |
| Device<br>Description: | SIGNA™ Hero is a whole body magnetic resonance scanner designed to support high resolution, high signal to-noise ratio, and short scan times. The systems use 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 oblique planes, using various pulse sequences, imaging techniques and reconstruction algorithms. The system features a 3.0T superconducting magnet with 70cm bore size. The system is designed to conform to NEMA DICOM standards (Digital Imaging and Communications in Medicine). |
| Indications for Use | The SIGNA™ Hero 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™ Hero 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. |
| Technology: | The SIGNA™ Hero employs the same fundamental scientific technology as its predicate device. SIGNA™ Hero offers two magnet configurations, building on the 3.0T 3TLC magnet, and introducing the newly designed 3.0T ARES (Platform) magnet. SIGNA™ Hero builds on the existing Gradient Driver design, RF transmit architecture design, RF receive chain design and software platform. SIGNA™ Hero offers a detachable eXpress patient table, similar to detachable tables available on other GEHC 3T MR systems. |
| Comparison of<br>Indications<br>for Use | The changes in technology do not impact the indications for use.<br>The indications for use have not changed, other than to reflect the<br>SIGNA™ Hero product name.<br>Therefore, the intended use is the same as the predicate device in<br>accordance with the FDA's guidance document “The 510(k)<br>Program: Evaluating Substantial Equivalence in Premarket<br>Notifications [510(k)]”, dated 28 July 2014. |
| Comparison of<br>Technological<br>Characteristics | Overall, the SIGNA™ Hero employs the same fundamental<br>scientific technology as the predicate device.<br><b>System Design:</b> There are one notable technological difference<br>between the SIGNA™ Hero and the predicate device: the 3.0T<br>ARES (Platform) magnet.<br><b>Operating Principles:</b> The SIGNA™ Hero functions using the<br>same operating principles as the predicate device.<br><b>Materials:</b> The SIGNA™ Hero and the predicate device both use<br>flame retardant materials.<br><b>Safety and Performance Testing:</b> Both the SIGNA™ Hero and<br>the predicate device comply with the same safety and performance<br>testing (see Determination of Substantial Equivalence, below).<br>These technological differences do not raise any different<br>questions regarding safety and effectiveness. Both devices must<br>address questions of whether they provide an adequate level of<br>image quality appropriate for diagnostic use. The performance<br>data described in this submission include results of both bench<br>testing and clinical testing that show the image quality<br>performance of SIGNA™ Hero compared to the predicate device. |
| Determination of<br>Substantial<br>Equivalence: | <b>Summary of Non-Clinical Tests:</b><br>The SIGNA™ Hero and the predicate device were subject to<br>similar risk management testing to demonstrate substantial<br>equivalence of safety and performance.<br>Testing to the following voluntary standards included:<br>• ANSI/AAMI ES60601-1<br>• IEC 60601-1-2 |
| | |
| IEC 60601-2-33<br>IEC 62304<br>ISO 10993-1<br>●<br>IEC 62464-1<br>In addition, the SIGNA™ Hero complies with applicable NEMA MS | |
| 3, NEMA MS 4, NEMA MS 8, and the NEMA PS3 standard for | |
| DICOM, as does the predicate device. | |
| Both the SIGNA™ Hero and the predicate device have a | |
| successful biocompatibility track record, as demonstrated by ISO | |
| 10993-1 testing and by the patient contacting materials' history of | |
| use in previously cleared devices. | |
| The following quality assurance measures were applied to the | |
| development of the subject device, as they were for the predicate | |
| device: | |
| Risk Analysis | |
| Requirements Reviews | |
| Design Reviews | |
| Testing on unit level (Module verification) | |
| Integration testing (System verification) | |
| Performance testing (Verification) | |
| Simulated use testing (Validation) | |
| Summary of Clinical Tests: | |
| The subject of this premarket submission, the SIGNA™ Hero, did | |
| not require clinical studies to support substantial equivalence. | |
| Sample clinical images have been included in this submission. | |
| The sample clinical images demonstrate acceptable diaqnostic | |
| image performance of the SIGNA™ Hero in accordance with the | |
| FDA Guidance "Submission of Premarket Notifications for | |
| Magnetic Resonance Diagnostic Devices" issued on November 18, | |
| 2016. The image quality of the SIGNA™ Hero is substantially | |
| equivalent to that of the predicate device. | |
| | |
| | |
| | <b>Substantial Equivalence Conclusion:</b> |
| | The indications for use of the proposed device are comparable to<br>the claimed predicate device. The SIGNA™ Hero employs<br>equivalent technology to the claimed predicate device.<br>Additionally, the results from the above non-clinical tests<br>demonstrate that the device performs as intended. Therefore, the<br>SIGNA™ Hero is substantially equivalent to the predicate device to<br>which it has been compared. |
| Conclusion: | In conclusion, GE Healthcare considers the SIGNA™<br>Hero to be as safe, as effective, with performance that<br>is substantially equivalent to the predicate device. |
