The description focuses on post-processing of MR data to generate parametric maps and different image contrasts based on physical parameters (R1, R2, PD, TE, TR, TI). There is no mention of AI or ML algorithms being used for this processing or analysis.
No
The device is described as a post-processing software medical device for visualization and analysis of MR imaging data for diagnostic purposes, not for treating any condition.
Yes
The device is described as a "medical device intended for use in visualization of the brain" and "SyMRI images can provide information useful in determining diagnosis," which explicitly states its role in aiding diagnosis.
Yes
The device is described as "post-processing software medical device" and its function is to analyze input data from MR imaging systems to generate parametric maps and image contrasts. While it relies on input data from an MR imaging system (hardware), the device itself is solely performing software-based analysis and processing of that data. The description focuses entirely on the software's capabilities and functions.
Based on the provided text, SyMRI is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The text explicitly states that SyMRI analyzes "input data from MR imaging systems" and is used for "visualization of the brain" and "head imaging." It processes imaging data, not biological samples.
- The intended use is for visualization and analysis of MR images. The description focuses on generating parametric maps and different image contrasts from MR data to aid in diagnosis when interpreted by a physician. This is characteristic of medical imaging software, not IVD devices.
Therefore, SyMRI falls under the category of medical imaging software, not an IVD.

Intended Use / Indications for Use
SyMRI is a post-processing software medical device intended for use in visualization of the brain. SyMRI analyzes input data from MR imaging systems. SyMRI utilizes data from a multi-delay, multi-echo acquisition (MDME) to generate parametric maps of R1, R2 relaxation rates, and proton density (PD). SyMRI can generate multiple image contrasts from the parametric maps. SyMRI enables post-acquisition image contrast adjustment. SyMRI is indicated for head imaging. When interpreted by a trained physician, SyMRI images can provide information useful in determining diagnosis. SyMRI should always be used in combination with at least one other, conventional MR acquisition (e.g. T2-FLAIR).

Device Description
SyMRI allows the user to generate multiple image contrasts from a single acquisition scan. This is accomplished by post-processing a multi-delay, multi-echo acquisition (MDME) into parametric maps. The parametric maps are R1, R2 relaxation rates, and proton density (PD). The inverse relaxation parameters, T1 relaxation time (1/R1), and T2 relaxation time (1/R2) are also provided as parametric maps. The parametric maps can be visualized as contrast weighted MR images, such as T1, T2, PD, and Inversion Recovery (IR) weighted images (including T1-FLAIR, T2-FLAIR, STIR, Double IR, and PSIR weighted images). SyMRI calculates the pixel signal intensity as a function of R1, R2, PD, and desired MR scanner settings, such as echo time (TE), repetition time (TR), and inversion delay time (TI). A number of default settings for TE. TR, and TI are provided, but the user has the ability to change the contrast of the images. SyMRI generates all the different image contrasts from the same parametric maps, derived from the same acquisition. This leads to enhanced image slice registration, owing to the absence of interacquisition patient movement. SyMRI provides the user the ability to change the contrast of the images after the acquisition. This is performed by adjusting the TE, TR, and/or TI parameters post-acquisition, to generate the specific contrast desired.
SyMRI also provides image processing tools to extract the values of the parametric maps per individual pixel, per region of interest, or the entire imaging volume.
SyMRI is intended to be used on MDME sequence data from GE MAGiC.

003 510k Summary
SyMRI is intended to be used on MDME sequence data from GE MAGiC.
Comparison of Technological Characteristics
SyMRI and MAGiC are the same algorithm for post processing, MAGiC also includes acquisition. Input data to SyMRI and MAGiC is MDME acquisition. SyMRI and MAGiC both uses a single scan to acquire a multi-delay, multi- echo acquisition (MDME) data to generate parametric maps of R1, R2 relaxation rates, and proton density (PD) This data is used to generate images, which are possible to adjust, even post acquisition. In SyMRI the parametric maps are used to produce the synthetic images - as in MAGiC. SyMRI is the same as MAGiC post processing.
By virtue of its intended use and physical and technological characteristics, SyMRI is substantially equivalent to the predicate devise that has been cleared for marketing in the US. The performance data shows that SyMRI is as safe and effective as the predicate device.
Performance Data Quality and Safety:
SyMRI was designed in compliance with following standards:
- AAMI/ANSI 62304- Medical Device software Software life cycle processes ●
- NEMA PS 3.1 3.20 (2016) DICOM Format ●

- IEC 62366-1:2015 Application of usability engineering to medical devices ●
- IEC82304-1:2016 Health Software Part 1: General requirements for product safety ●
Testing to Support of Substantial Equivalence Determination
Verification and validation was performed according to SyntheticMR processes. Additional phantom head to head comparison of R1, R2 and PD parametric maps, which included one contrast of each major synthetic image (T1w, T2w, T2 FLAIR), were performed to compare SyMRI to MAGiC. There was no difference between SyMRI and MAGiC.
