Intended Use

The uMR 680 system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces sagittal, transverse, coronal, and oblique cross sectional images, and spectroscopic images, and that display internal anatomical structure and/or function of the head, body and extremities. These images and the physical parameters derived from the images when interpreted by a trained physician yield information that may assist the diagnosis. Contrast agents may be used depending on the region of interest of the scan.

Device Story

uMR 680 is a 1.5T superconducting MRI system; 70cm bore. Inputs: RF signals from patient anatomy via specialized coils (including new 24-channel breast coil). Operation: System components (magnet, gradient coils, spectrometer, computer) acquire and process signals to generate anatomical and spectroscopic images. Includes Magnetic Resonance Elastography (MRE) functionality (epi_se_mre sequence). Used in clinical settings by trained physicians/technicians. Output: Cross-sectional images and physical parameters interpreted by radiologists to assist diagnosis. Benefits: Enhanced diagnostic imaging capabilities for breast and tissue elasticity assessment.

Clinical Evidence

Bench testing only. Included NEMA MS 1, 3, 6, 9 (SNR/Uniformity), NEMA MS 14 (surface heating), ANSI/AAMI ES60601-1 (electrical/mechanical safety), and IEC 60601-1-2/4-2 (EMC). Biocompatibility evaluated per ISO 10993-1. Clinical image quality for breast coil and MRE performance (accuracy, repeatability, reproducibility) verified via phantom and volunteer testing; image quality confirmed sufficient for diagnostic use by U.S. Board Certified radiologist.

Technological Characteristics

1.5T superconducting MRI; 70cm bore. Components: magnet, RF power amplifier, RF coils, gradient power amplifier/coils, patient table, spectrometer. Connectivity: DICOM/NEMA compliant. Biocompatibility: ISO 10993-1 compliant. Software: MRE (epi_se_mre) and 24-channel breast coil integration.

Indications for Use

Indicated for use as an MR diagnostic device to produce cross-sectional and spectroscopic images of the head, body, and extremities to display internal anatomical structure and/or function. For use by trained physicians to assist in diagnosis. Contrast agents may be used.

Regulatory Classification

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).

Special Controls

*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.

Dear Xin Gao:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

The test results demonstrated that the device performed as expected and thus, it is substantial equivalent to the predicate devices to which it has been compared.

#### Conclusion 9.

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, we conclude that uMR 680 Magnetic Resonance Diagnostic Device is substantially equivalent to the predicate device. It does not introduce new indications for use, and performance test results support that the technical characteristic change of the Breast Coil - 24 (i.e., the number of channels in the coil) and incorporating MRE/epi_se_mre do not introduce new potential hazards or safety risks.
