The summary describes standard image processing techniques (reconstruction, filtering, motion correction, quantitative calculations) and does not mention any AI/ML terms or concepts.
No
The device is described as a software application for the analysis and display of medical images and the processing of data to derive diagnostic information, not for direct therapeutic intervention.
Yes
The 'Intended Use / Indications for Use' section explicitly states that "The results of this processing may be used in determining the presence of cardiac diseases." This directly indicates a diagnostic purpose.
Yes
The device is described as a "software application" that processes data from a separate hardware device (nuclear medicine gamma camera) and outputs data for visualization by another computer program or workstation. It does not include or require specific hardware components for its primary function.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples: IVDs are designed to examine specimens taken from the human body, such as blood, urine, tissue, etc., to provide information about a person's health.
- This device processes medical images: The ImagenSPECT™ 3.0 system processes images acquired from a nuclear medicine gamma camera. It analyzes and displays these images to aid in the diagnosis of cardiac diseases. It does not directly analyze biological samples.
The device falls under the category of medical imaging software, which is distinct from IVDs.

Intended Use / Indications for Use
The ImagenSPECT™ 3.0 system is a software application that provides a processing environment for the analysis and display of cardiac SPECT and planar images. The results of this processing may be used in determining the presence of cardiac diseases. Data for ImagenSPECT 3.0 is derived from a nuclear medicine gamma camera. The resulting datasets may be either planar or 3D tomograms of patient anatomy. This software can also be used for processing display and quantitation of multigated acquisition blood pool scans (MUGA) specifically the left ventricular ejection fraction (LVEF). ImagenSPECT™ 3.0 can also be used for quantitation of planar and SPECT, early and late 99mTc pyrophosphate images.

Device Description
ImagenSPECT™ 3.0 is a Windows application which allows physicians and healthcare professionals to inspect, reconstruct and reorient myocardial perfusion SPECT images. The system processes gated and ungated SPECT cardiac images to create 3D tomographic data. The user can correct for patient motion, change filter settings, change reconstruction settings, range of reconstruction, and reorientation angles. The application also models the influence of distance dependent blur. The use of this system is limited to qualified, licensed healthcare providers (radiologists, nuclear cardiologists or nuclear medicine physicians) trained in the use of nuclear medicine imaging devices.
This software also processes, display and performs quantitative calculations of LVEF on multigated acquisition blood pool scans (MUGA). ImagenSPECTT™ 3.0 is used to quantitate the uptake of 99™Tc pyrophosphate in early and late planar and SPECT studies.
The ImagenSPECTTM 3.0 system is designed to take nuclear medicine data from commercially available SPECT systems and process the data into a format that can be visualized by a separate computer program or workstation.
In addition, quarter-counts, half dose and/or half-time scans can be reconstructed with ImagenSPECT™ 3.0 using resolution recovery, iterative reconstruction and is equivalent to the predicate ImagenSPECT™ (K152503) using half-counts and full counts (full-time scan, half dose/ half-time, full dose).

Summary of Performance Studies
ImagenSPECT™ 3.0 was tested in phantom and patient data to verify the successful performance of additional features.
- Comparison of 99mTc pyrophosphate heart contralateral ratios from ImagenSPECT 3.0 with heart contralateral ratios from the Siemens e.soft system.
- Quantitative measurements of MUGA derived LVEF using ImagenSPECT 3.0 were correlated with LVEF measurements determined using the Siemens e.soft system.
- One quarter time myocardial perfusion SPECT testing was examined in both phantom and patient studies. Phantom studies demonstrated signal-to-noise ratio. Patient studies compared ImagenSPECT 3.0 reconstructions with conventional ordered subsets expectation maximization (OSEM) reconstructions, analyzed using a 17 segment polar map of tracer uptake.
Key Metrics
- 99mTc pyrophosphate heart contralateral ratios: Pearson correlation coefficient (r) = 0.96, p value for student paired t-test = 0.15 (between ImagenSPECT 3.0 and Siemens e.soft).
- MUGA derived LVEF: r = 0.92, not statistically different (p = 0.13) (between ImagenSPECT 3.0 and Siemens e.soft system).
- One quarter time myocardial perfusion SPECT (phantom): 98.9% of the signal-to-noise using one quarter time reconstructed with ImagenSPECT 3.0 compared to full-time unfiltered reconstructed perfusion images.
- One quarter time myocardial perfusion SPECT (patient): average segmental difference between full-time OSEM and one quarter time ImagenSPECT 3.0 was 5.9%, P value of the paired t-test was 0.76.

F. Comparison of Technical Characteristics to Predicate Device:
The ImagenSPECT™ 3.0 system and its predicates, the ImagenSPECT™ (K152503) and the e.Cam/e.Soft™ system use the same type of data sets for analysis and calculation of data. -
G. Device performance, verification and validation
ImagenSPECT™ 3.0 was tested in phantom and patient data to verify the successful performance of additional features. Specifically, this includes the quantitative assessment of LVEF on multigated acquisition blood pool scans (MUGA), quantitative uptake of 99mTc pyrophosphate and one quarter time myocardial perfusion SPECT testing.
99mTc pyrophosphate heart contralateral ratios from ImagenSPECT 3.0 was compared with heart contralateral ratios from the Siemens e.soft system. The Pearson rorrelation coefficient (r) between ImagenSPECT 3.0 and Siemens e.soft was 0.96 and the p value for student paired t-test was 0.15.
5
Ouantitative measurements of MUGA derived LVEF using ImagenSPECT 3.0 were correlated with LVEF measurements determined using the Siemens e.soft system (r=0.92) and were not statistically different (p=0.13).
One quarter time myocardial perfusion SPECT testing was examined in both phantom and patient studies. Phantom studies demonstrated that a change in signal-to-noise ratio 98.9% of the signal-to-noise using one quarter time reconstructed using ImagenSPECT 3.0 when compared to full-time unfiltered reconstructed perfusion images. One quarter time patient studies reconstructed using ImagenSPECT 3.0 were compared with conventional ordered subsets expectation maximization (OSEM) reconstructions. Myocardial perfusion SPECT images were analyzed using a 17 segment polar map of tracer uptake. The average segmental difference between full-time OSEM and one quarter time ImagenSPECT 3.0 was 5.9% and the P value of the paired t-test was 0.76.
In addition to testing ImagenSPECT 3.0 clinical performance, ImagenSPECT 3.0 was also successfully tested for the success of risk mitigation strategies.
- H. Summary:
Testing and comparison of technological characteristics and intended uses found that all components of the ImagenSPECT™ 3.0 system are equivalent to the predicates. In addition, quarter-counts, e.g. half dose and/or half-time, reconstructed with ImagenSPECT™ 3.0 using resolution recovery, iterative reconstruction was equivalent to the predicate ImagenSPECT™ (K152503) using half-counts and full counts (full-time scan, half dose/ half-time, full dose).
