Intended Use
The GE MyoSPECT and MyoSPECT ES systems are a medical tool intended for use by appropriately trained healthcare professionals to aid in detecting, localizing and diagnosing of cardiac diseases and heart function for the evaluation of diseases, abnormalities, and disorders. The systems output can also be used by the physician for planning, guiding, and monitoring. MyoSPECT and MyoSPECT ES perform Nuclear Medicine (NM) imaging procedures for the detection of radioisotope tracer uptake in the patient body, using tomographic scanning of single or multi-isotopes with either single or multi energy peaks. The tomographic scanning is supported by various acquisition types. The GE MyoSPECT and MyoSPECT ES systems include signal analysis and display equipment, patient and equipment supports, components and accessories. The systems may include data and image processing to produce reconstructed trans-axial images can also be post processed to obtain additional images, imaging planes, analysis results and uptake quantitation. The systems may be used for patients of all ages.

## Marketed Devices
MyoSPECT and MyoSPECT ES are a modification to the predicate Discovery NM 530c. The primary changes are the introduction of nine (9) detectors configuration on MyoSPECT ES, an option for Extended Field of View (EFOV) processing, enhanced patient positioning workflow, and replacing the patient table with the patient table from the reference NM 830 device. A nineteen (19) detector configuration remains on MyoSPECT, as the current production version of the predicate device.
#### Device Description
The GE MyoSPECT and MyoSPECT ES are Single Photon Emission Computed Tomography (SPECT) systems intended for nuclear cardiology imaging. MyoSPECT and MyoSPECT ES include a nuclear medicine imaging system using a CZT-based multi-detector array. MyoSPECT ES are identical systems that are differentiated by the number of detectors within the multi-detector array. MyoSPECT is offered with 19 detectors as opposed to 9 detectors for MyoSPECT ES is upgradable to MyoSPECT. The MyoSPECT and MyoSPECT ES systems do not introduce any new Intended Use.
The multi-detector array on MyoSPECT ES has a multi-pinhole collimator providing each detector with a pinhole collimator that is focused on a volume in space, all together forming the Quality Field of View (Q.FOV) in which the patient heart is positioned for a cardiac scan.
MyoSPECT and MyoSPECT ES add an option for Extended Field of View (EFOV) processing that enables more flexible positioning. The predicate device patient positioning workflow is also enhanced to provide users with visual means of the Q.FOV and EFOV boundaries, and recommendations on the use of Q.FOV

## Technological Characteristics
MyoSPECT and MyoSPECT ES employ the same fundamental scientific technology as the predicate and reference devices. The three systems share the same CZT multi-detector array, except for difference in the number of detectors within the array. The detectors acquire projections simultaneously, without system motion. The acquired projections are processed into trans-axial images using the same methods for the three systems. The table below summarizes the substantive feature/technological differences between the predicate device and the proposed device:

### Determination of Substantial Equivalence
### Summary of Non-Clinical, Design Control Testing
MyoSPECT and MyoSPECT ES have successfully completed the design control testing per our quality system. No additional hazards were identified, and no unexpected test results were observed. MyoSPECT and MyoSPECT ES were designed under the Quality System Regulations of 21CFR 820 and ISO 13485. GE believes that the extensive bench testing and the physician evaluations performed are sufficient for FDA's substantial equivalence determination.
MyoSPECT and MyoSPECT ES have has been independently tested and conforms with IEC 60601-1 Ed. 3.1 and its applicable Collateral and Particular Standards.
The following quality assurance measures have been applied to the development of the system:
- Requirement Definition
- Risk Analysis
- Technical Design Reviews
- Formal Design Reviews
- · Software Development Lifecycle
- Testing on unit level (Module verification)
- · Integration testing (System verification)
- · System Testing:
- o Safety Testing (Verification)
- System and Image Performance Testing (Verification)
- o Simulating Use Testing (Validation)
The testing and results did not raise new or different questions of safety and effectiveness than associated with predicate device. We consider the proposed device is substantially equivalent to the predicate device.
The substantial equivalence is also based on the software documentation for a "Moderate" level of concern. GE believes that MyoSPECT and MyoSPECT ES is of comparable type and substantially equivalent to the predicate device.
#### Additional Non-Clinical Testing
Engineering bench testing was performed to support substantial equivalence, demonstrate performance, and substantiate the product claims. This included testing for:
- I SPECT Resolution
- Image Uniformity and Contrast
- Energy resolution and simultaneous multi-isotope acquisition
- Extended Field of View
- Smart Positioning Q.FOV / EFOV Workflow

## Clinical Testing
A clinical reader study using 28 studies for MyoSPECT and 32 studies for MyoSPECT ES was performed by three experience NM physicians. The exams constituted a clinically representative sample for evaluation of MyoSPECT's and MyoSPECT ES's performance. The results of the study support the determination of substantial equivalence. The three experienced NM physicians scored the images using 5-point Likert scales for overall image quality. All the physicians attested that their assessments demonstrated acceptable diagnostic results.
## Substantial Equivalence Conclusion
The changes associated with MyoSPECT and MyoSPECT ES do not create a new Intended Use and represent equivalent technological characteristics, with no impact on the control mechanisms, operating principle, and energy type. GE's quality system's design verification, and risk management processes did not identify any new questions of safety or effectiveness, hazards, unexpected results, or adverse effects stemming from the changes to the predicate.
Based on development under GE Healthcare's quality system, the successful system and software verification and validation testing, conformance to standards, the additional engineering bench testing, and the clinical reader study demonstrates that MyoSPECT and MyoSPECT ES are substantially equivalent to, and hence as safe and as effective for its Intended Use, as the legally marketed predicate device.
