The description focuses on established image processing algorithms (BOLD, DTI, DSC Perfusion) and does not mention AI or ML.
No
The device provides analysis and visualization of MRI data for diagnostic purposes, not direct treatment or therapy.
Yes
Explanation: The device provides analysis and visualization capabilities of dynamic MRI data to present derived properties and parameters in a clinically useful context, which suggests its use in understanding a patient's condition. While it doesn't directly state a diagnosis, its features like BOLD, DTI, and DSC Perfusion analysis are tools used by medical professionals to aid in clinical diagnosis.
Yes
The device description explicitly states that Brainance MD is a "web-accessible medical viewing and post-processing software application" and describes its functionalities solely in terms of software-based analysis and visualization of existing MRI data. There is no mention of any hardware components being part of the device itself.
No, 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.
- Brainance MD's Function: Brainance MD processes and analyzes imaging data (MRI scans) of the brain. It does not analyze biological samples taken from the patient.
Therefore, based on the provided information, Brainance MD falls under the category of medical imaging software, not an In Vitro Diagnostic device.

Device Description
Brainance MD is a web-accessible medical viewing and post-processing software application. Brainance MD offers comprehensive functionality for dynamic image analysis and visualization of brain MRI data which are acquired through DICOM compliant imaging devices and modalities.
The following algorithms provide the main functional analyses of the software application.
- · BOLD: BOLD fMRI analysis is used to highlight small magnetic susceptibility changes in the human brain in areas with altered bloodflow 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 Perfusion: Calculations of perfusion related parameters that provide information about the blood vessel structure and characteristics. Examples of such maps are blood flow, time to peak, mean transit time and leakage.
Apart from the aforementioned functionalities, Brainance MD offers general visualization tools, a data upload, data download and a reporting feature.

Description of the test set, sample size, data source, and annotation protocol
A comparative study was conducted in order to validate the equivalence of results computed by Brainance MD and the primary predicate device reqarding the processing of DSC Perfusion, fMRI and DTI sequences. Towards this direction two sequences that were part of two different exams/subjects (either healthy control or diseased) were selected for the comparison conducted for each modality. The subjects selected were all adults and either healthy controls or diseased diagnosed with metastasis or glioblastoma multiforme.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Type: Comparative study; Software verification and validation testing.
Sample Size: For the comparative study, two sequences were selected for each modality (DSC Perfusion, fMRI, DTI) from two different exams/subjects.
Key Results: The final results matched the criteria of acceptance/approval priorly set by the manufacturer and thus equivalent the two devices on a result level was proven.
Standalone Performance: Not Found
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The maps that resulted from the processing were compared using ICC & Bland-Altman analysis on all valid pixel values for every subject in the dataset. The fiber tracts that resulted were compared using Mean Relative Difference (MRD) as Percentage across each tract, which is the mean across samples of the absolute difference divided by the maximum absolute value.
