Yes
The "Intended Use / Indications for Use" section explicitly states, "It is indicated for use as a diagnostic imaging device."
No
The device description explicitly states it is a "whole body magnetic resonance scanner" and details hardware components like a "1.5T superconducting magnet with 60 cm bore size," indicating it is a hardware device with integrated software.
Based on the provided information, the SIGNA Prime Elite is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- SIGNA Prime Elite Function: The SIGNA Prime Elite is a magnetic resonance scanner. It produces images of the internal structures and functions of the body in vivo (within the living body) using magnetic fields and radio waves. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's a "diagnostic imaging device" to produce images and spectra of the entire body. These images are interpreted by a trained physician to assist in diagnosis. This is characteristic of an imaging device, not an IVD.
Therefore, the SIGNA Prime Elite falls under the category of a diagnostic imaging device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The SIGNA Prime Elite is a whole body magnetic resonance scanner designed to support high signal-to-noise ratio, and short scan times. It is indicated for use as a diagnostic imaging device to produce axial, sagittal, coronal, and oblique images, spectroscopic images, parametric maps, and/or spectra, dynamic images of the structures and/or functions of the entire body, including, but not limited to, head, neck, heart, abdomen, pelvis, joints, prostate, blood vessels, and musculoskeletal regions of the body.
Depending on the region of interest being imaged, contrast agents may be used. The images produced by SIGNA Prime Elite reflect the spatial distribution or molecular environment of nuclei exhibiting magnetic resonance.
These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.
