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 SyMRI is indicated for head imaging.
SyMRI is also intended for automatic labeling, visualization and volumetric quantification of segmentable brain tissues from a set of MR images. Brain tissue volumes are determined based on modeling of parametric maps from MDME.
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),

The provided text is a 510(k) clearance letter from the FDA for a device named SyMRI. It describes the device's indications for use and classification but does not contain any information about the acceptance criteria or the study that proves the device meets those criteria.
Therefore, I cannot fulfill your request for the specific details regarding:
- A table of acceptance criteria and the reported device performance
- Sample sizes and data provenance
- Number and qualifications of experts for ground truth
- Adjudication method
- MRMC comparative effectiveness study and effect size
- Standalone performance
- Type of ground truth used
- Training set sample size
- Ground truth establishment for the training set
The document primarily focuses on the regulatory clearance of the SyMRI device based on its substantial equivalence to predicate devices, rather than detailing the performance studies conducted to establish that equivalence.
§ 892.1000 Magnetic resonance diagnostic device.
(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
