The summary describes a new set of coils for an existing MRI system. There is no mention of AI or ML in the intended use, device description, or performance studies. The focus is on the hardware components and their performance metrics (SNR, uniformity).
No
The device is used for diagnostic imaging to produce images that assist trained physicians in determining a diagnosis, rather than directly treating a condition.
Yes
The document explicitly states that the device is "indicated for use as a diagnostic imaging device" and that the images produced "provide information that can be useful in determining a diagnosis."
No
The device description explicitly states that the Flex Loop Coil Set 3 T consists of physical components including coils, an interface, preamplifiers, cable traps, and a combiner network. These are hardware components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "MR examination of the human body" and to "produce transversal, sagittal, coronal and oblique images of the internal structures of the body." This describes an in vivo (within the living body) imaging process, not an in vitro (outside the living body) diagnostic test performed on biological samples.
- Device Description: The device is a set of coils used in conjunction with an MRI scanner. This is consistent with an imaging device, not a device for analyzing biological samples.
- Input Imaging Modality: The input modality is Magnetic Resonance, which is an imaging technique applied to the body.
- Anatomical Site: The device is used to image "internal structures of the body," again indicating an in vivo application.
- Performance Studies: The performance studies focus on metrics relevant to imaging quality (Signal to Noise Ratio, Image Uniformity), not metrics related to the accuracy of analyzing biological samples.
IVD devices are typically used to examine specimens such as blood, urine, or tissue to detect diseases, conditions, or infections. This device is used to create images of the body itself.

Intended Use / Indications for Use
The intended use of the Flex Loop Coil Set 3 T is, in conjunction with a Magnetic Resonance Scanner, the MR examination of the human body. Maghed in the MAGNETOM 3 T Trio, A Tim System, the Flex Loop Coils are intended to produce transversal, sagittal, coronal and oblique images of the internal structures of the body.
Used in the MAGNETOM 3 T Trio, a Tim System, the Flex Loop Coils are indicated for use as a diagnostic imaging device to produce transversal, sagittal, coronal and oblique images of the internal structures of the body. The images produced by the MAGNETOM 3 T Trio, a Tim System with the Flex Loop Coils reflect the spatial distribution of protons (hydogen nuclei) exhibiting magnetic resonance.
When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis.
The intended use of the MAGNETOM 3 T Trio, a Tim System is not affected in any way by the use of the new Flex Loop Coil Set 3 T.

(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.

Summary of Technological Characteristics of the Principal Device as Compared with the Predicate Device
Although the new Flex Loop Coils are designed for a field strength of 3 T, we believe that they are substantially equivalent to the predicate Flex Loop Coils for 1.5 T MAGNETOM Systems.
General Safety and Effectiveness Concerns
The following safety and performance parameters:
[Safety]
- Maximum Static Field
- Rate of Change of Magnetic Field
- RF Power Deposition
- Acoustic Noise Level
[Performance]
- Geometric Distortion
- Slice Profile, Thickness and Gap
- High Contrast Spatial Resolution
specified by the FDA Guidance document for MR Diagnostic Devices are unaffected by the modifications described within this notification.
The following parameters were considered for the new Flex Loop Coil Set 3 T
{Safety| - Biocompatibility
[Performance] - Signal to Noise Ratio
- Image Uniformity
No new materials were used for the new Flex Loop Coil Set 3 T compared to their predicate devices. Therefore no biocompatibility tests were performed. Signal to Noise Ratio (SNR) and image uniformity tests acc. to NEMA MS-6 standard were performed for the new Flex Loop Coil Set 3 T and the results presented in this submission show that they are equivalent with the predicate devices.
Conclusion as to Substantial Equivalence
Laboratory and clinical testing was performed to support this claim of substantial equivalence and to show that the technological differences do not raise any new questions pertaining to safety and effectiveness.
