No
The provided text describes a standard MRI device and its intended use for diagnostic imaging. There is no mention of AI, ML, image processing beyond standard MRI reconstruction, or any data sets/performance studies typically associated with AI/ML algorithms.
No
The device is described as being for "diagnostic MRI imaging" and produces images to "provide diagnostically useful information," indicating it is used for diagnosis, not therapy.
Yes
The text explicitly states: "If interpreted by a medical expert, these images can provide diagnostically useful information." This indicates the device aids in diagnosis.
No
The description focuses on the output of an MRI machine, which is a hardware device. There is no mention of the device itself being software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The description clearly states that the device is an MRI machine used for imaging internal structures of the body. It produces images based on the magnetic resonance properties of protons within the body.
- No Specimen Analysis: There is no mention of the device analyzing any specimens taken from the body.
Therefore, this device falls under the category of an in vivo diagnostic imaging device, not an in vitro diagnostic device.

Intended Use / Indications for Use
The intended use of Paramed's MRJ product is for diagnostic MRI imaging of the hip, knee, ankle, foot, shoulder, elbow, wrist, hand, calf, thigh, arm, forearm, TMJ and cervical spine with limitation to joint pathologies -- no tumors, no angiography. The device produces transverse, sagittal, coronal and oblique cross-sectional images, displaying the internal structure of the limbs and joints being imaged. The images produced correspond to the spatial distribution of protons (hydrogen nuclei) that check the magnetic resonance properties and depend on the MR parameters (spin-lattice relaxation time -- T1, spin-spin relaxation time -- T2, nuclei density, flow velocity and chemical shift). If interpreted by a medical expert, these images can provide diagnostically useful information.

§ 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.

Dear Ms. Upton:
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, 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act), 21 CFR 1000-1050,

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of the letter:
