No
The summary describes a traditional MRI system with a unique mechanical design for intra-operative use. There is no mention of AI or ML in the intended use, device description, or performance studies.
No
The device is described as a "magnetic resonance diagnostic device" used to produce images and spectra that "assist in diagnosis," not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the iMRI 1.5T A and 3T S are "magnetic resonance diagnostic device (MRDD)".
No
The device description explicitly states that the iMRI systems are "a traditional MRI unit that has been suspended on an overhead rail system" and lists major components including the "Siemens MAGNETOM MRI system with minor modifications; IMRIS Magnet Mover System, OR Table, RF coils and 3-pin head fixation device." This clearly indicates the presence of significant hardware components, not just software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body, such as blood, urine, or tissue, outside of the body to provide information for diagnosis, monitoring, or screening.
- Device Function: The description clearly states that the iMRI system is a "magnetic resonance diagnostic device (MRDD)" that produces images and spectra of the internal structure and function of the head, body, or extremities. This is done in vivo (within the living body).
- Intended Use: The intended use is for diagnostic imaging, intra-operative imaging, and interventional procedures, all of which involve imaging the patient directly.
- No Mention of Specimens: There is no mention of the device being used to analyze samples or specimens taken from the body.
Therefore, the iMRI system described is an in vivo diagnostic imaging device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The iMRI 1.5T A and 3T S are indicated for use as a magnetic resonance diagnostic device (MRDD) that produces transverse, sagittal, coronal and oblique cross sectional images, spectroscopic images and / or spectra, and that displays the internal structure and / or function of the head, body or extremities.
Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, contrast agents may be used. These images and/or spectra and the physical parameters derived from the images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.
The iMRI 1.5T A and 3T S systems may also be used for imaging during intra-operative and interventional procedures when performed with MR safe devices or MR conditional devices approved for use with the MR scanner.
The iMRI 1.5T A and 3T S MRI systems may also be used for imaging in a multi-room suite.

Device Description
The IMRIS Intraoperative MRI systems (iMRI 1.5T A and iMRI 3T S) are a traditional MRI unit that has been suspended on an overhead rail system, and is designed to operate inside an RF shielded room to facilitate intra-operative and multi-room use. The magnet is normally situated in a diagnostic room until imaging is requested. For Diagnostic room purposes, the system retains the standard diagnostic features of an MRI system. The diagnostic room is separated from the intra-operative suite by sliding doors that are part of the facility structure.
The iMRI system (1.5T A/3T S) is a tool for radiologists and surgeons, used to acquire images for diagnostic, intra-operative or interventional procedures. For OR purposes, high-resolution images can be obtained immediately prior to surgical incision, intraoperative and after wound closure. The iMRI 1.5T A is based on the IMRIS Neuro II-SE predicate cleared under 510(k) K071099 and the Siemens MAGNETOM Aera/Skyra MRI system cleared under 510(k) K101347. The iMRI 3T S is based on the IMRIS Neuro III-SV cleared under 510(k) K083137 and the Siemens MAGNETOM Aera/Skyra MRI system cleared under 510(k) K101347. The major components of the iMRI systems are: the Siemens MAGNETOM MRI system with minor modifications; IMRIS Magnet Mover System, OR Table, RF coils and 3-pin head fixation device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The iMRI systems (1.5T A and 3T S) have been designed to provide MRI imaging in an intra-operative setting in the same manner as the predicate Neuro systems (Neuro II-SV and Neuro II-SE System). The iMRI 3T S/1.5T A intra-operative features, including the Magnet Mover Assembly, OR Patient Table, Intraoperative Coil and Head Fixation Device are substantially equivalent to the same intra-operative features of the predicate Neuro III-SV/ Neuro II-SE. The iMRI systems (1.5T A and3T S) do not raise any new safety or effectiveness issues related to the use of a moving MRI system in an intra-operative setting.
The iMRI systems (1.5T A and 3T S) MRI imaging system's software and hardware are substantially equivalent to the Siemens MAGNETOM Skyra and Aera. The iMRI systems (1.5T A and 3T S) do not raise any new safety issues related to static magnetic field effects, changing magnetic field effects, RF heating or acoustic noise or effectiveness issues related to specification volume, signal to noise, image uniformity, and geometric distortion, slice profile, thickness and gap, or high contrast spatial resolution.
Testing has been completed to verify the equivalence to the Siemens MAGNETOM Skyra and Aera System and to verify the safe and effective intra-operative operation of the iMRI systems (1.5T A and 3T S).
iMRI systems (1.5T A and 3T S) verification and validation supports a determination of substantial equivalence.

Dear Mr. Job:
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. 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 (reporting of medical device-related adverse events) (21 CFR 803); 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.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Small Manufacturers, International and Consumer Assistance at its toll
