Intended Use
The MAGNETOM SYMPHONY with the Sonata Gradients is a whole body scanner with higher gradient amplitudes. The MAGNETOM SYMPHONY with the Sonata Gradients is indicated for use as diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the head or body. The images produced by the MAGNETOM SYMPHONY with the Sonata Gradients reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin lattice relaxation time (T1), spin-spin relaxation time (T") and flow. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.

No
The document describes a standard MRI system and does not mention any AI or ML capabilities in its intended use, device description, or performance studies.

No
The device is indicated for diagnostic imaging to produce images for diagnostic purposes, not for therapy.

Yes
The "Intended Use / Indications for Use" section explicitly states, "The MAGNETOM SYMPHONY with the Sonata Gradients is indicated for use as diagnostic imaging device..." and later mentions that the images "provide information that can be useful in determining a diagnosis."

No

The device description explicitly states it is a "whole body scanner," which is a hardware device. The summary describes a physical system for producing images, not a software application.

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.
  • Device Function: The description clearly states the MAGNETOM SYMPHONY is a "whole body scanner" that produces images of the internal structures of the head or body using Magnetic Resonance. It works by detecting the spatial distribution of protons within the body.
  • No Sample Analysis: The device does not analyze samples taken from the body. It directly interacts with the body to generate images.

Therefore, based on the provided information, the MAGNETOM SYMPHONY is an in vivo diagnostic imaging device, not an in vitro diagnostic device.

§ 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.

II. Safety and Effectiveness Information Supporting Substantial Equivalence.

• Device Description:

· Intended Use

The MAGNETOM SYMPHONY with the Sonata Gradients is a whole body scanner with higher gradient amplitudes. The MAGNETOM SYMPHONY with the Sonata Gradients is indicated for use as diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the head or body. The images produced by the MAGNETOM SYMPHONY with the Sonata Gradients reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin lattice relaxation time (T1), spin-spin relaxation time (T") and flow. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.

• Technological Characteristics

The MAGNETOM Symphony with the new Sonata Gradients is substantially equivalent to the MAGNETOM Symphony System.

· General Safety and Effectiveness Concerns:

Operation of the MAGNETOM Symphony with the new Sonata Gradients is substantially equivalent to the commercially available MAGNETOM Symphony System. The following are the safety parameter with action levels:

  • Maximum Static Field ●
  • Rate of Change of Magnetic Field .
  • . RF Power Deposition
  • Acoustic Noise Levels .

and performance levels

  • . Specification Volume
  • . Signal to Noise
  • . Image Uniformity
  • Geometric Distortion .
  • Slice Profile, Thickness and Gap .
  • High Contrast Spatial Resolution .

specified by the FDA guidance document for MR Diagnostic Devices were evaluated within this notification. The reduction in the minimum rise time of the system will affect both the acoustic noise level and the rate of change in the magnetic field strength (dB/dt), as well as certain performance levels with the system. However, the new levels are not significantly changed and, in the case of safety, parameters remain below the level of concern.

• Substantial Equivalence:

Laboratory testing were performed to support this claim of substantial equivalence and to show that the technological differences do not raise any new questions pertaining to safety and effectiveness.

Dear Ms. Yieh:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613.
