Intended Use
The Quadrature and Phased Array Flexible Body Coils do not change the intended use of the Picker 1.5T EDGE system. The 1.5T EDGE system is intended for use as a NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR, (2) depend upon NMR parameters (proton density, flow velocity, spin-lattice relaxation time T1, spin-spin relaxation time T2) and (3) display the soft tissue structure of the head and whole body. When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis. The Quadrature and Phased Array Flexible Body Coils are indicated for use in the following anatomic regions and with the designated nuclei: Anatomic Regions: Liver, kidneys, adrenal glands, spleen, bilateral hips and associated abdominopelvic structures Nuclei Excited: Hydrogen
Device Description
The Picker Flexible Body Coils have either a Quadrature or Phased Array coil architecture enclosed in a flexible package that can be wrapped around the area of interest. The coils are designed to give improved signal-to-noise ratio, image resolution and image acquisition time over that of the standard EDGE body coil.
More Information

No
The document describes a new coil for an existing MRI system, focusing on hardware improvements (signal-to-noise ratio, image resolution, acquisition time) and does not mention any software or processing features related to AI or ML.

No.
The device is used to produce images for diagnostic purposes, not for therapeutic treatment.

Yes
The device is described as an "NMR device that produces images" which, "When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis." This explicitly states its role in diagnosis.

No

The device description explicitly states it is a "coil architecture enclosed in a flexible package," indicating a physical hardware component.

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 function: The description clearly states that this device is a component (flexible body coils) for a Magnetic Resonance Imaging (MRI) system. MRI is an imaging modality that produces images of the internal structure of the body using magnetic fields and radio waves. It does not involve testing samples taken from the body.
  • Intended Use: The intended use is to produce images that can be interpreted by a trained physician to aid in diagnosis. This is consistent with the function of an imaging device, not an IVD.

Therefore, the Quadrature and Phased Array Flexible Body Coils, as described, are part of an imaging system and 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.
