Outputs: visualization of functional maps, 2D/3D images, and reports. Used in clinical environments by radiologists or medical technicians to optimize workflow efficiency. Healthcare providers use outputs to assess brain function and structure, aiding clinical decision-making regarding neurological conditions.

Clinical Evidence

Bench testing only. Verification and validation activities were performed to ensure the software meets design and performance specifications and user needs.

Indications for Use

Indicated for analysis and visualization of dynamic brain MRI data to present derived properties and parameters in a clinical context. Intended for use by trained medical personnel (radiologists or technicians).

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).

# Device Description

The nordicBrainEx Software is a post-processing application for dynamic MRI data developed with focus on ease of use and high performance on a standard Windows workstation. The software provides comprehensive functionality for dynamic image analysis and visualization of MRI data, where signal changes over time are analyzed to determine various modality dependent functional parameters. The following algorithms provide the main functional analyses of the application.

- BOLD: BOLD fMRI analysis is used to highlight small magnetic susceptibility changes in the ● human brain in areas with altered blood-flow resulting from neuronal activity.
- DTI: Diffusion analysis is used to visualize local water diffusion properties from the analysis of � diffusion-weighted MRI data. Fiber tracking utilizes the directional dependency of the diffusion to display the white matter structure in the brain.
- DSC: Calculations of perfusion related parameters that provide information about the blood . vessel structure and characteristics. Examples of such maps are blood volume, blood flow, time to peak, mean transit time and leakage.

In addition to these specific functional analyses, the application also provides general visualization tools, a database for data handling, and a reporting feature. This is to ensure that the workflow of the application is optimized to ensure efficiency and high throughput in a clinical environment.

### Intended Use

nordicBrainEx is an advanced visualization and processing software, with specific focus on providing algorithms designed to analyze functional MR data of the brain. The software runs on a standard "offthe-shelf" PC workstation and can be used with data and images acquired through DICOM compliant imaging devices and modalities.

The software is intended to be used by medical personnel, such as radiologists or medical technicians, trained in the methods provided by the application. In order to best accommodate this group of users, it is specifically designed to have an easy to use and streamlined workflow, as well as an intuitive graphical user interface.

## Indications For Use

nordicBrainEx provides analysis and visualization capabilities of dynamic MRI data of the brain, presenting the derived properties and parameters in a clinically useful context.

The indications for use of the predicate device, nordic!CE, is formulated in a more general way with focus on delivering specific functionality to a clinical environment. However, since those functionalities are the same as those in nordicBrainEx the more specific indications of nordicBrainEx are considered to be substantially equivalent to those of nordicICE. See SE discussion for more details.

## Technological Characteristics and Substantial Equivalence

The nordicBrainEx Software is substantially equivalent to the nordicICE Software (K090546) in technological characteristics and operational characteristics.

More details can be found in the substantial equivalence discussion.

The rationale for determining the substantial equivalence between nordicBrainEx and nordiclCE is based on the defined intended use, indications for use, and the technical and operational characteristics of the two applications. To verify that nordicBrainEx fulfils the defined characteristics and requirements, it has been subject to extensive in-house testing (see section below). The successful completion of said tests verifies the claimed characteristics of nordicBrainEx, and thus supports the determination of substantial equivalence.

## Performance Testing

Prospectively defined verification and validation activities for the nordicBrainEx Software assure that the nordicBrainEx Software meets design and performance specifications as well as user needs when operated according to the operating instructions.
