Regulatory Classification

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.

Device Description:

Common/Usual Name:

Discovery MR750w 3.0T (K103327)

The Discovery MR750w 3.0T features a superconducting magnet operating at 3.0 Tesla. The data acquisition system accommodates up to 32 independent receive channels in various increments, and multiple independent coil elements per channel during a single acquisition series. The system uses a combination of time-varying magnetic fields (gradients) and RF transmissions to obtain information regarding the density and position of elements exhibiting magnetic resonance. The system can image in the sagittal, coronal, axial, oblique and double oblique planes, using various pulse sequences and reconstruction algorithms. The Discovery MR750w 3.0T uses multi-drive RF transmit for imaging of the head and body regions. The Discovery MR750w 3.0T is designed to conform to NEMA DICOM standards.

The images produced by the Discovery MR750w 3.0T reflect the spatial distribution or molecular environment of nuclei exhibiting magnetic resonance. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.

The Discovery MR750w 3.0T employs the same Technology: fundamental scientific technology as its predicate device Discovery MR750w 3.0T (K103327). It is a whole body magnetic resonance scanner designed to support high resolution, high signal-to-noise ratio, and short scan times. It employs the same multi-drive RF transmit technology as its predicate. The modified device enables multi-drive RF transmit for head scanning, in addition to body scanning. There have been no hardware changes to enable multi-drive RF transmit for head scanning, it is solely a software change.
