## Intended Use

To be used in conjunction with a Magnetic Resonance Scanner to produce images of the knee that can be interpreted by a trained physician.

## Device Story

HRK-123 Knee Array Coil is an accessory for Magnetic Resonance (MR) scanners; functions as a radiofrequency (RF) receiver coil to capture MR signals from the knee anatomy. Device transforms received RF signals into image data for display on MR scanner console. Used in clinical radiology settings by trained technologists/radiologists. Output provides diagnostic images for physician interpretation to assist in clinical decision-making regarding knee pathology. Benefits include high-resolution imaging of knee structures.

## Clinical Evidence

Bench testing only.

## Technological Characteristics

RF receiver coil for MR imaging; form factor specific to knee anatomy; connects to MR scanner system; passive device component; non-invasive.

## Regulatory 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).

## Special Controls

*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.
