Indications for Use
The MAGNETOM system is indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and/or spectra, and that displays the internal structure and/or function of the head, body, or extremities. Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These images and/or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis. The MAGNETOM system may also be used for imaging during interventional procedures when performed with MR compatible devices such as in-room displays and MR Safe biopsy needles.
Device Story
MAGNETOM Viato.Mobile is a magnetic resonance diagnostic device (MRDD) used in clinical settings by trained physicians to acquire and interpret cross-sectional images, spectroscopic images, and spectra of the head, body, or extremities. The system utilizes magnetic resonance imaging (MRI) technology to display internal structures and functions, aiding in clinical diagnosis. This version introduces a new XQ gradient coil and gradient power amplifier, replacing the XJ gradient system found in the predicate. The device supports interventional procedures when used with MR-compatible accessories like biopsy needles and in-room displays. Healthcare providers use the generated images to inform clinical decision-making. The system is designed for professional use, ensuring patient benefit through non-invasive diagnostic visualization.
Clinical Evidence
No clinical data or clinical studies were conducted. Substantial equivalence is supported by non-clinical bench testing, including verification and validation of the new hardware and system-level electrical safety and electromagnetic compatibility (EMC) testing per IEC 60601-1-2.
Technological Characteristics
Magnetic resonance diagnostic device; utilizes XQ gradient coil and gradient power amplifier. Conforms to IEC 60601-1 (General safety), IEC 60601-1-2 (EMC), IEC 60601-2-33 (MR safety), and NEMA MS 4 (Acoustic noise). Software: syngo MR XA51A. Operates via standard MR imaging principles. Sterilization not applicable; device is for professional clinical use.
Indications for Use
Indicated for patients requiring MR diagnostic imaging of head, body, or extremities; produces cross-sectional images, spectroscopic images, and spectra to assist in diagnosis; usable for interventional procedures with MR-compatible devices.
Regulatory Classification
Identification

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 Alina Goodman:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

# 12. Conclusion as to Substantial Equivalence
MAGNETOM Viato.Mobile with software syngo MR XA51A and XQ gradient system has the same intended use and same basic technological characteristics than the predicate device system, MAGNETOM Viato.Mobile with syngo MR XA51A and XJ gradient system, with respect to the magnetic resonance features and functionalities. There are no differences in technical features compared to the predicate device, but new hardware. The resulting differences have been tested and the conclusions from all verification and validation data suggest that the system bears an equivalent safety and performance profile to that of the predicate device and reference device.
Siemens believes that MAGNETOM Viato.Mobile with software syngo MR XA51A and XQ gradient system is substantially equivalent to the currently marketed device MAGNETOM Viato.Mobile with software syngo MR XA51A and XJ gradient system(K232482, cleared on September 6, 2023).
