No
The summary describes an MRI coil, which is a hardware component used for signal acquisition. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance studies focus on hardware characteristics like SNR and image uniformity.

No.
The device is described as an MRI coil used for imaging musculoskeletal, soft tissue, and vascular structures of the lower extremities, which is a diagnostic function, not a therapeutic one.

No

Explanation: This device is an MRI coil, which is a component used with an MRI system to acquire images. It does not perform image interpretation or diagnosis itself; it is an imaging accessory.

No

The device description explicitly states it is a "Phased Array Lower Extremity Coil," which is a hardware component used in MRI systems. The performance studies also focus on hardware-related metrics like Signal-to-Noise Ratio and Image Uniformity.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The provided description clearly states that this device is a "Magnetic resonance imaging (MRI) of the musculoskeletal structures, soft tissue and vascular structures of the lower extremities." It's a coil used in an MRI system to acquire images of the body.
  • No Sample Analysis: The device does not analyze any samples taken from the body. It's a component of an imaging system that interacts with the patient's body directly to generate images.

Therefore, based on the intended use and device description, this is an imaging device, not an in vitro diagnostic device.

Summary of Performance Studies

The device was evaluated for safety parameters (Maximum Static Magnetic Field, Rate of Magnetic Field Strength Change, RF Power Deposition, Acoustic Noise Levels, Biocompatibility) and imaging performance parameters (Specification Volume, Signal-to-Noise Ratio, Image Uniformity, Geometric Distortion, Slice Thickness and Gap, High Contrast Spatial Resolution, Fast Imaging Protocol Compatible).

Key Results:

  • Safety parameters: No change due to coil for Static Magnetic Field, Rate of Magnetic Field Strength Change, Acoustic Noise Levels, and Biocompatibility. RF Power Deposition was improved.
  • Imaging Performance Parameters: Specification Volume of 15-16 cm typical FOV all planes. 3 Times Improvement over predicate device in peripheral regions for Signal-to-Noise Ratio. No change for Image Uniformity, Geometric Distortion, Slice Thickness and Gap, and High Contrast Spatial Resolution. Compatible with Fast Imaging Protocol.

§ 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.

Overview

The Radiology Devices Panel considered potential concerns regarding the safe and effective operation of Magnetic Resonance Diagnostic Devices when they recommended reclassification to Class II on July 27, 1987. After reclassification, the FDA's Center for Devices and Radiological Health (CDRH) released a draft guidance document for the content and review of Magnetic Resonance Diagnostic Device premarket notification submissions that offered clarification of these concerns. Due to considerable technological advances in MRDDs, CDRH issued an updated guidance document on November 14, 1998. The following is a summary of the information contained within this premarket notification that addresses these concerns:

The GE and Siemens 1.5T and 3.0T MRI systems, operated with the Medical Advances 8 Channel T/R Phased Array Lower Extremity Coil, are substantially equivalent to the GE Signa 1.5T system operated with the legally marketed predicate devices listed in scction 4.0, within the Class II definition of Magnetic Resonance Diagnostic Device with respect to the safety parameter action levels:

Safety Parameters

Maximum Static Magnetic Field:No change due to coil
Rate of Magnetic Field Strength Change:No change due to coil
RF Power Deposition:Improved
Acoustic Noise Levels:No change due to coil
Biocompatibility:No change
