The document describes standard MRI technology and image processing techniques, with no mention of AI, ML, or related concepts.
No
The device is described as an imaging device intended for diagnosis, not for treatment or therapy.
Yes
Explanation: The "Intended Use / Indications for Use" section states, "When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination." This clearly indicates its role in the diagnostic process.
No
The device description explicitly states it is a "Magnetic Resonance Imaging System that utilizes a 0.7 Tesla superconducting magnet in an open gantry," indicating it is a hardware system, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is an "imaging device" that provides "physiological and clinical information" through "images." It does not mention analyzing samples of human origin (like blood, urine, tissue, etc.) outside of the body.
- Device Description: The description confirms it's a "Magnetic Resonance Imaging System," which is an imaging modality, not a device designed for in vitro testing.
- Input Imaging Modality: The input is "Magnetic Resonance Imaging (MRI)," which is an in vivo imaging technique.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body to detect diseases, conditions, or infections. This device does not perform such tests.
The device is an imaging system used to visualize internal structures of the body, which is a different category of medical device than an IVD.

§ 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.
