More Information

No
The summary does not mention AI, DNN, or ML, nor does it describe any training or test sets typically associated with AI/ML development. The focus is on software upgrades and new imaging sequences.

No
The described device is used for imaging, which is a diagnostic purpose, not a therapeutic one.

Yes
The device is described as an upgrade to existing MRI systems (FLEXART and VISART) and its Intended Use / Indications for Use section clearly states "Imaging of: The Whole Body..." for various anatomical sites and imaging techniques (e.g., MRCP, MR Angiography). MRI is an imaging modality used for diagnostic purposes, and the output (images) is used by healthcare professionals to diagnose conditions.

No

The device is described as a software upgrade to existing Magnetic Resonance Imaging (MRI) systems (MRT-50GP/E2, MRT-50GP/H2, MRT-150/F1, MRT-150/F2). While it is a software component, it is explicitly tied to and functions as part of a larger hardware system (the MRI scanner) and is not a standalone software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use describes imaging of various parts of the body using Magnetic Resonance (MR). This is a diagnostic imaging technique performed in vivo (within the living body), not in vitro (outside the body, typically on biological samples).
  • Device Description: The device is a software upgrade for existing MR imaging systems. MR systems are used for diagnostic imaging, not for testing biological samples.
  • Lack of IVD Indicators: There are no mentions of analyzing biological samples, performing tests on bodily fluids or tissues, or providing results related to the chemical, biological, or immunological state of a patient's sample.

The information clearly points to a medical imaging device used for diagnostic purposes on the patient, which falls under a different regulatory category than IVDs.

§ 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.
