Intended Use
The Emory Cardiac Toolbox™ 4.0 – 4.3 software program should be used for the quantification of myocardial perfusion for the display of wall motion and quantification of left-ventricular function parameters from SPECT & PET myocardial perfusion studies (EGS™) including to quantitatively evaluate the wall motion and wall thickening of the heart using longitudinal, radial, and circumferential strain measurements, for the 3D alignment of coronary artery models from CT coronary angiography onto the left ventricular 3D epicardial surface and analysis of the CT data to evaluate calcified plaques in the coronary arteries, for the assessment of cardiac mechanical dyssynchrony using phase analysis, for generation of the short axis, vertical, and horizontal long axis tomograms from the SPECT raw data using either filtered back projection (FBP) or iterative reconstruction (MLEM/OSEM), for the quantification of myocardial blood flow and coronary flow reserve, and for the decision support in interpretation (LVX) and automatic structured reporting of the study.
Device Description
The Emory Cardiac Toolbox™ 4.3 is used to display gated wall motion and for quantifying parameters of left-ventricular perfusion and function from gated SPECT & PET myocardial perfusion studies and for the evaluation of dynamic PET studies.
More Information

No
The summary describes standard image processing and quantitative analysis techniques for cardiac imaging, without mentioning AI or ML. The performance studies focus on correlation with existing methods and clinical outcomes, not on the performance metrics typically associated with AI/ML model validation (e.g., sensitivity, specificity of a classification task).

No.
The device is described as software used for quantification, display, and analysis of medical images and data, rather than directly treating or preventing disease.

Yes

The device is used for "quantification of myocardial perfusion," "quantitatively evaluate the wall motion and wall thickening of the heart," "analysis of the CT data to evaluate calcified plaques," "assessment of cardiac mechanical dyssynchrony," and "quantification of myocardial blood flow and coronary flow reserve," all of which are activities that identify or measure a disease or condition. The "decision support in interpretation" also indicates diagnosis.

Yes

The device is described as a "software program" and its function is to process and analyze medical images and data. There is no mention of any accompanying hardware component that is part of the device itself.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Emory Cardiac Toolbox™ software processes and analyzes medical images (SPECT, PET, and CT) of the heart. It quantifies parameters related to myocardial perfusion, left-ventricular function, wall motion, strain, coronary artery calcification, and blood flow.
  • Input Data: The input data is imaging data, not biological samples.
  • Output: The output is quantitative data and visual representations derived from the images, not diagnostic results from analyzing biological samples.

While the software provides information that can be used to aid in diagnosis and treatment decisions, it does so by analyzing images of the body, not by performing tests on samples taken from the body. Therefore, it falls under the category of medical imaging software, not In Vitro Diagnostics.

Emory-CACS: The CACS module was validated against the FDA approved Siemens SynqoVia™ toolbox (K201034). A clinical comparison test was the method used for validation. The test data was comprised a group of 52 patients using 110 vessels with calcified plaques that had been previously scored by Emory radiologists; the same lesions selected by the radiologist were analyzed by the Emory-CACS and SYngo.CT CaScoring modules.
ECTb™ Strain: Validation of strain analysis for ECTb™ 4.3 was performed in 80 patients with variable coronary artery disease (CAD) and 22 patients with low-risk of CAD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Emory-CACS: A clinical comparison test was the method used for validation. The test data was comprised a group of 52 patients using 110 vessels with calcified plaques that had been previously scored by Emory radiologists; the same lesions selected by the radiologist were analyzed by the Emory-CACS and SYngo.CT CaScoring modules. Regression analysis was performed between the SyngoVia™ and the Emory-CACS module. On a per patient basis, linear plaque volume regression (m = 1.10; b = 0.46) produced an r2 = 0.99 and Agatston score regression (m = 1.01; b = 1.06) produced an r2 > 0.99. The values obtained by the Emory-CACS module demonstrated excellent correlations with the Syngo.CT CaScoring developed by Siemens Medical Solutions.

ECTb™ Strain: MPI measurements were validated for resting global longitudinal strain vs. an accepted reference standard, TTE echo. A clinical comparison test was the method used for validation. Longitudinal, radial, and circumferential strains from a low-risk cohort (n=22) were used to establish normal limits to evaluate against the results of a high-risk cohort (n=80). Positive strain, lower limits of normal were determined as the mean radial strain minus 2-standard deviations (SD). For circumferential and longitudinal strains, both negative in sign, lower limits of normal were determined as the mean strain plus 2-SDs. In the CAD cohort, longitudinal strain assessed with PET MPI and TTE were strongly correlated at stress (r= 0.68, p
