The summary describes image processing and modeling tracer uptake over time, but there is no mention of AI, ML, deep learning, or neural networks. The performance studies focus on simulations and synthesized data, not the typical training and testing of an AI/ML model.
No.
The device processes images to aid in diagnosis, but does not directly provide therapy.
Yes
The device aids in the processing of PET images to help in the diagnosis of myocardial perfusion by addressing corrections and producing output images for review by medical professionals, which is a step in the diagnostic process.
Yes
The device description explicitly states "MFI-Cardiac is a software medical device". It receives DICOM images as input and outputs corrected DICOM images, indicating it operates solely on digital data without requiring or including any 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 (like blood, urine, tissue) outside of the body. The MFI-Cardiac application processes medical images (PET scans) acquired from within the patient's body.
- The intended use and device description clearly state that it processes PET images. It takes DICOM images as input and outputs corrected DICOM images for review.
- There is no mention of analyzing any biological samples or performing tests on specimens.
The device is a software medical device intended for image processing and analysis, not for in vitro diagnostic testing.

Intended Use / Indications for Use
The MFI-Cardiac application is intended to provide processing of rest and stress myocardial perfusion positron emission tomography (PET) images with approved radiotracers that have been acquired with a singlescan or fast back-to-back scans without waiting for radiotracer decay between scans. The application models measurements of tracer uptake over time to aid in the processing of the images. Co-registration or fusion of volumetric data is provided as a quality control. The processed output images are reviewed on other devices by qualified medical professionals trained in the use of medical imaging devices.

Device Description
MFI-Cardiac is a software medical device that facilitates the rapid acquisition and processing of rest and stress myocardial perfusion images (MPI) with positron emission tomography (PET) and approved radiotracers. The device processes rest+stress cardiac PET images that have been rapidly acquired using either a single scan with two administrations of the tracer (one at rest, the other at stress) or separate "back-to-back" rest and stress scans. The rapidly acquired rest and stress cardiac PET images are provided to MFI—Cardiac via digital image transfer in DICOM format.
In use, the device first performs a series of quality assurance tests to ensure data integrity and validity. The images are then processed to correct for residual activity from the 1st tracer administration (administered at rest) that affects the image obtained after the 2nd tracer injection (administered at stress). The device then outputs separated and corrected DICOM images at rest and stress; these images are offloaded to other devices for display and review by qualified healthcare professionals.

Summary of Performance Studies
Three performance evaluation studies were completed with all acceptance criteria met:
(1) Simulation studies to evaluate device performance across the full range of rest and stress myocardial blood flows that are anticipated to be encountered clinically;
(2) Performance evaluation using patient dataset with synthesized rest+stress images to evaluate the performance of MFI-Cardiac for producing output (corrected) rest and stress images that are equivalent to rest and stress images obtained from separate scans: and
(3) Evaluation of rest-stress image co-reqistrations performed by MFI-Cardiac for ensuring that the estimate for residual rest tracer activity is aligned with the stressphase images before the correction is applied. This evaluation was also performed using patient datasets with synthesized rest+stress images.

2. Device Description
MFI-Cardiac is a software medical device that facilitates the rapid acquisition and processing of rest and stress myocardial perfusion images (MPI) with positron emission tomography (PET) and approved radiotracers. The device processes rest+stress cardiac PET images that have been rapidly acquired using either a single scan with two administrations of the tracer (one at rest, the other at stress) or separate "back-to-back" rest and stress scans. The rapidly acquired rest and stress cardiac PET images are provided to MFI—Cardiac via digital image transfer in DICOM format.

In use, the device first performs a series of quality assurance tests to ensure data integrity and validity. The images are then processed to correct for residual activity from the 1st tracer administration (administered at rest) that affects the image obtained after the 2nd tracer injection (administered at stress). The device then outputs separated and corrected DICOM images at rest and stress; these images are offloaded to other devices for display and review by qualified healthcare professionals.
3. Intended Use
The MFI–Cardiac application is intended to provide processing of the biodistribution of radionuclides in the body using tomographic images. The application models measurements of tracer uptake over time to aid in the processing of myocardial perfusion emission tomographic images. Co-registration or fusion of volumetric data is provided as a quality control. The processed output images are reviewed on other devices by qualified medical professionals trained in the use of medical imaging devices.
The intended use of the new device is the same, but not identical to that of the predicate device (Corridor 4DM v2010); however, the differences do not alter the intended therapeutic use of the device nor do they affect the safety and effectiveness of the subject device relative to the predicate. Both the subject and predicate devices are intended to provide processing of the biodistribution of radionuclides in the body using tomographic images and both are used for rest-stress myocardial perfusion imaging in nuclear cardiology.

5. Performance Data
The performance data provided in this submission in support of the substantial equivalence determination are described in the subsections below:
Software Verification and Validation
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device is considered to pose a "moderate" level of concern, since a failure or latent flaw in the software could directly result in minor injury to the patient.
Performance Evaluations
Three performance evaluation studies were completed with all acceptance criteria met:
(1) Simulation studies to evaluate device performance across the full range of rest and stress myocardial blood flows that are anticipated to be encountered clinically;
(2) Performance evaluation using patient dataset with synthesized rest+stress images to evaluate the performance of MFI-Cardiac for producing output (corrected) rest and stress images that are equivalent to rest and stress images obtained from separate scans: and
(3) Evaluation of rest-stress image co-reqistrations performed by MFI-Cardiac for ensuring that the estimate for residual rest tracer activity is aligned with the stressphase images before the correction is applied. This evaluation was also performed using patient datasets with synthesized rest+stress images.
Human Factors / Usability Study
Human factors engineering for MFI-Cardiac included preliminary human factors analyses, formative evaluations, implementation of design changes that mitigate or eliminate use-related hazards, and human factors validation testing. The results of validation testing indicate that MFI-Cardiac is safe and effective for the intended users, uses and use environments. Residual risks that remain would not be further reduced by modifications of user interface design or labeling (User Manual and Supporting Documents), and are outweighed by the benefits that may be derived from the device's use.
Conclusion / Summary of Substantial Equivalence 6.
The results of the non-clinical, human factors engineering, and simulated use tests and software verification and validation studies demonstrate the safety and effectiveness of the subject device and equivalence with the predicate device. Based on the information and data provided and analyzed in this 510(k) premarket notification, MultiFunctional Imaging, LLC concludes that MFI-Cardiac is substantially equivalent to the predicate device and is safe and effective for its intended use.
