Intended Use

The MRI-Q System is intended to provide additional processing of images for the analysis of multi-slice gradient echo MRI data sets of cardiac tissue to quantify the signal decay rate (R2*) and time (T2*).

Device Story

MRI-Q System is a standalone software package for cardiac MRI analysis. It imports multi-slice gradient echo MRI datasets via DICOM. The software provides an image viewer for browsing datasets and performing region of interest (ROI) analysis. It transforms input signal intensities by fitting signal decay curves on a voxel-by-voxel basis to calculate signal decay rate (R2*) and time (T2*). The system is used by clinicians to quantify cardiac tissue parameters, aiding in clinical decision-making regarding iron overload or other cardiac tissue characterizations. It functions as a post-processing tool for existing MRI data.

Clinical Evidence

No clinical data provided. The submission relies on bench testing and the demonstration of substantial equivalence to legally marketed predicate devices.

Technological Characteristics

Standalone software package. Operates on DICOM-compliant multi-slice gradient echo MRI data. Principle of operation: voxel-by-voxel fitting of signal decay curves to determine R2* and T2* values. Software-based processing.

Indications for Use

Indicated for quantitative analysis of magnetic resonance image signal decay parameters in cardiac tissue. Used for importing, viewing, and performing region of interest analysis on DICOM cardiac MRI datasets to measure R2* and T2* decay rates.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

Predicate Devices

PREDICATE DEVICE(S):

- K043271: Resonance Health Analysis Services R2-MRI Analysis System
- K073194 Cardiovascular Imaging Solutions Ltd. CMRtools and plug-in ThalassaemiaTools

DEVICE DESCRIPTION: Stand alone software package used to facilitate the import, visualization and analysis of multi-slice gradient echo MRI data sets encompassing cardiac tissue, to quantify the signal decay rate (R2*) and time (T2*).

- SCIENTIFIC CONCEPTS: The operational principle of the MRI-Q System is based on fitting signal decay curves to magnetic resonance image signal intensities acquired at different echo times on a voxel-by-voxel (3-D pixel) basis to determine the signal decay rate (R2*) and time (T2*).
#### INTENDED USE: The MRI-Q System is intended to provide additional processing of images for the analysis of multi-slice gradient echo MRI data sets of cardiac tissue to quantify the signal decay rate (R2*) and time (T2*).

## SUBSTANTIAL EQUIVALENCE INFORMATION:

The device has been shown to be substantially equivalent to the Resonance Health Analysis Services R2-MRI Analysis System (K043271) and the Cardiovascular Imaging Solutions Ltd CMRtools and plug-in ThalassaemiaTools (K073194).

### CONCLUSION:

The 510(k) premarket notification for the MRI-Q System contains adequate information and data to enable the FDA-CDRH to determine substantial equivalence to the predicate devices.

Dear Mr. Holland:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition. FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
