Intended Use
MRopen 0.5 T is a diagnostic total body imaging device with the following limitation: no cardiac imaging, no breast imaging. MRopen 0.5 T tomograph produces transverse, sagittal, coronal and oblique cross-sectional images that display the internal structure of the body. The examinations may be performed both in weight free (supine or seated position) and weight bearing position. The images produced reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The MR parameters that determine image appearance are proton density, spin-lattice relaxation time (Tl), spin-spin relaxation time (T2), chemical shift and flow velocity. When interpreted by a trained physician, these images can yield information that can be useful in the determination of a diagnosis.

More Information

No
The document describes modifications to an existing MRI device, focusing on hardware changes, a new DWI technique, and a new user interface. There is no mention of AI, ML, or any related image processing or analysis techniques that would typically indicate the use of such technology.

No
Explanation: The device is described as a "diagnostic total body imaging device" that produces images useful "in the determination of a diagnosis," not for treatment.

Yes

The "Intended Use / Indications for Use" section explicitly states, "MRopen 0.5 T is a diagnostic total body imaging device." Additionally, it mentions that the images produced "can yield information that can be useful in the determination of a diagnosis" when interpreted by a trained physician.

No

The device description explicitly states that the device is a total body magnetic resonance imaging device and details significant hardware components and modifications, including a magnet, spectrometer, compressors, cold heads, RFA, coils, and patient support. While it mentions software updates (User Interface and DWI technique), it is clearly not a software-only device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health.
  • Device Function: The MRopen 0.5 T is a Magnetic Resonance Imaging (MRI) device. It produces images of the internal structure of the body directly by interacting with the patient's body using magnetic fields and radio waves. It does not analyze specimens taken from the body.
  • Intended Use: The intended use clearly states it's a "diagnostic total body imaging device" that produces "cross-sectional images that display the internal structure of the body." This aligns with the function of an imaging device, not an IVD.

Therefore, the MRopen 0.5 T is a medical imaging device, not an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol

A test was performed on healthy volunteers who agreed to cooperate to demonstrate performance of the device on humans. The healthy volunteers were adult male and female aged between 20 and 60 available in our firm. Only main changes were tested.

New DWI technique base on HASTE readout sequence: The images on healthy volunteers conform to the expected image quality. Both ADC calculated image and DWI images along the three main directions are displayed.

New Long Spine coil: The use of this new receiving coil has been referred to the previous spine model for equivalent or better quality image, with the workflow improvement of not new coil positioning in case of multiple scan of different streches of spine. Performance test report in Section 18.

Shoulder coil New model: This design is exactly the same employed in MrJ 3300 secondary predicate device which better fits the new patient comfort accessories during shoulder exam. Performance test report in Section 18.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Study Type: Non-clinical (bench) and clinical (healthy volunteers)
Sample Size: Healthy volunteers (adult male and female aged between 20 and 60 available in the firm). Specific sample size not provided.
Key Results: The non clinical (bench) and clinical (healthy volunteers) data demonstrate MRopen 0.5T to be as safe, as effective and performs as well than the predicates. Mropen 0.5 T is substantially equivalent to the legally marketed devices and conforms to applicable medical device safety and performance standards.

Dear Luisella De Benedetti:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see
