The document describes standard image processing and quantitative analysis techniques for cardiac PET images, with no mention of AI or ML algorithms.
No.
The device is an aiding tool for clinicians to perform analysis of PET images and assist in interpretation by quantification. It does not provide therapy or treatment.
Yes
The device is an "aiding tool for the clinicians to perform analysis" of images and to quantify various cardiac metrics (e.g., perfusion, volumes, ejection fraction, myocardial mass) and their severity to "assist clinical interpretation," particularly for patients with suspected or known coronary artery disease. This function of analyzing, quantifying, and assisting in the interpretation of medical data to identify or assess a disease or condition falls under the definition of a diagnostic device. While it states the clinician remains ultimately responsible for the final assessment and diagnosis, the device clearly provides data and analysis that directly support diagnostic conclusions.
Yes
The device description explicitly states it is a "new software device" and describes its functionalities as integrating and building upon existing software platforms for image display and analysis. There is no mention of accompanying hardware components.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
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: CardIQ Flow is a software tool that analyzes images obtained from a PET scanner. It processes and quantifies data from these images to aid in the diagnosis and assessment of cardiac conditions. It does not directly analyze biological samples.
- Input: The input is PET image data, not biological specimens.
- Output: The output is quantitative measurements and visualizations derived from the image data, not results from a laboratory test on a biological sample.
Therefore, CardIQ Flow falls under the category of medical image analysis software, not In Vitro Diagnostics.

Intended Use / Indications for Use
CardIQ Flow is an aiding tool for the clinicians to perform analysis of stationary, dynamic, or gated cardiac position emission tomography (PET) images. The measurements include perfusion, end-diastolic volumes, stroke volume, ejection fraction, myocardial mass, and transient ischemic dilatation. Also included is a feature that enables clinicians to visualize reformatted data and make a comparison between stress and rest series. Software is indicated for determining regional and global absolute rest and stress myocardial perfusion in cc/min/g, Coronary Flow Reserve and their combination into the Coronary (CFC) Map in patients with suspected or known coronary artery disease (CAD) in order to assist clinical interpretation of PET perfusion images by quantification of their severty. It is intended for use by trained professionals, such as nuclear medicine or nuclear cardiology physicians, or cardiologists with appropriate training. The clinician remains ultimately responsible for the final assessment and diagnosis based on standard practices, clinical judgment and interpretation of cardiac images or quantitative data.

Device Description
The basis for this submission is the introduction of a new software device, CardIQ Flow which integrates the functionalities of the predicate devices HeartSee and FullCard Analysis for the display and analysis of Cardiac PET images. It is built within the framework of the Volume Viewer (K041521) 3D platform, intended to aid clinicians in assessing the myocardial perfusion, myocardial perfusion, myocardial blood flow and wall motion. It is used for the evaluation of patients with known or suspected coronary artery or ischemic heart disease.
This application can be used for:
· Reformatting axial data to the standard axis of the heart. Axial data may have been reconstructed using iterative or FBP algorithms with scatter and attenuation correction, if available.
• Analyzing the myocardial perfusion by the Vertical Long Axis (VLA), Horizontal Long Axis (HLA) and Short Axis (SA) obliques generated from the selected input data.
· Comparing myocardial perfusion in rest and stress studies as well as metabolism in viability studies.
- · Viewing wall motions via synchronized gated beating slices.
- · Investigating the entire left ventricle in one 2D Polar Plot that displays all short axis slices.
- · Comparing myocardial perfusion of corrected and uncorrected datasets.
· Calculation and evaluation of Myocardial Blood Flow (MBF), Coronary Flow Reserve (CFR), and Coronary Flow Capacity (CFC).
· Printing a report designed for referring physicians.

Intended use:
CardIQ Flow is a fully integrated post-processing and analysis tool tailored for PET cardiac imaging. CardIQ Flow is designed to provide an easy-to-use and efficient tool aiding clinical interpretation for patients with suspected or known coronary artery disease (CAD) with quantification of their severity.
Indications for use:
CardIQ Flow is an aiding tool for the clinicians to perform analysis of sets of stationary, dynamic, or gated cardiac positron emission tomography (PET) images. The measurements include perfusion, end-diastolic & end-systolic volumes, stroke volume, ejection, myocardial mass, and transient ischemic dilatation. Also included is a feature that enables clinicians to visualize reformatted data and make a comparison between stress and rest series. Software is indicated for determining regional and global absolute rest and stress myocardial perfusion in cc/min/g, Coronary Flow Reserve and their combination into the Coronary Flow Capacity (CFC) Map in patients with suspected or known coronary artery disease (CAD) in order to assist clinical interpretation of PET perfusion images by quantification of their severity. It is intended for use by trained professionals, such as nuclear technicians, nuclear cardiology physicians, or cardiologists with appropriate training. The clinician remains ultimately responsible for the final assessment and diagnosis based on standard practices, clinical judgment and interpretation of cardiac images or quantitative data.
Technological Characteristic:
CardIO Flow employs the same technologies as those of the Predicates.
HeartSee (K171303) is a software tool for cardiac positron emission tomography (PET) for determining regional and global absolute rest and stress myocardial perfusion in cc/min/g. Coronary Flow Reserve and their combination into the Coronary Flow Capacity (CFC) Map for facilitating the interpretation of PET perfusion images in patients with suspected of known coronary artery disease.
FullCard Analysis (K061587) is a post processing analysis software package designed to provide a totally integrated package including automated processing, visualization, quantification of parameters of myocardial perfusion and function, along with simple reporting capabilities. The parameters include perfusion, end-diastolic & end-systolic volumes, stroke volume, ejection fraction, myocardial mass, and transient ischemic dilatation.
CardIQ Flow is a software which integrates together the functionalities from HeartSee and FullCard Analysis in order to be able to display and analyze Cardiac PET images. CardIQ Flow when compared to HeartSee has the same workflow leading to the computation of the CFC (ROI Deposition, blood flow and CFR computation). CardIQ Flow has based the computation of the different maps on HeartSee's 2D formulas, but has tuned them to 3D in order to augment the clinical review capabilities. Similar to HeartSee, the segmentation in CardIQ Flow can be

manually adjusted using dedicated tools so that the user can control where blood flow will be computed.
CardIO Flow has the same workflow as FullCard Analysis and has incorporated the same formulas as FullCard Analysis to quantify the parameters (perfusion, end-diastolic & end-systolic volumes, stroke volume, ejection fraction, myocardial mass, and transient ischemic dilatation) of myocardial perfusion and function.
As CardIQ Flow is built within Volume Viewer, CardIQ Flow inherits the below existing capabilities from Volume Viewer:
- Display of the maps
- Display of the statistics
- Display of the CFC graph
- ROI deposition
- Report of the maps and statistics
