Intended Use
The Picker MR Spectroscopy Package is intended for use as a non-invasive diagnostic device that provides information based on relative concentrations of metabolites in body tissues. This NMR data in the form of spectra or spectral images reflect the NMR properties of proton density, spin-lattice relaxation time (T1), spin-spin relaxation time (T2), and chemical shift. When interpreted by a trained medical practitioner, these spectral data provide information that can be useful in making a diagnosis. This package is indicated for use as follows: Anatomical region: Head, whole body Nuclei Excited: 1H
Device Description
Picker's MR Spectroscopy Package described in this submission is a proton ('H) spectroscopy software option. The package includes both capabilities for single voxel proton (SVP) spectroscopy and chemical shift imaging (CSI). These techniques provide a non-invasive method for analyzing metabolite concentrations in the brain and throughout the body. The MR Spectroscopy Package does not include any additional risks to the patient other than those for standard MR imaging.
More Information

No
The document describes standard MR spectroscopy techniques (SVP and CSI) and their use in analyzing metabolite concentrations. There is no mention of AI, ML, or any related terms in the intended use, device description, or specific sections for AI/ML information. The interpretation is explicitly stated to be performed by a trained medical practitioner.

No.
The device is described as a non-invasive diagnostic device that provides information useful in making a diagnosis, not for treating conditions.

Yes

The "Intended Use / Indications for Use" section explicitly states, "The Picker MR Spectroscopy Package is intended for use as a non-invasive diagnostic device".

No

The device is described as a "software option" for an existing MR system and processes data from an MRI scanner, which is a hardware device. While the submission focuses on the software package, it is dependent on and integrated with a hardware system for data acquisition.

Based on the provided information, 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 Description: The Picker MR Spectroscopy Package is described as a "non-invasive diagnostic device" that uses Magnetic Resonance (MR) data from "body tissues." It analyzes the NMR properties of protons within the body directly, without requiring a sample to be taken from the body.
  • Intended Use: The intended use describes obtaining information based on relative concentrations of metabolites in body tissues, not from a sample taken from the body.

Therefore, because the device operates non-invasively on the body itself rather than on a sample taken from the body, it falls outside the definition of an In Vitro Diagnostic.

§ 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.

Dear Dr. Keeler:

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 III (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 Requlations, 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. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the requlation entitled. "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
