Intended Use

The GE Signa® Excite MR system is a whole body magnetic resonance scanner designed to support high resolution, high signal-to-noise ratio, and short scan times. The Signa Excite MR system is indicated for use as a diagnostic imaging device to produce axial, sagittal, coronal and oblique images, spectroscopic images, and/or spectra, dynamic images of the internal structures and organs of the head, neck, TMJ, spine, breast, heart, abdomen, pelvis, joints, prostate, and musculoskeletal regions of the body. The images produced by the Signa Excite system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. These images and/or spectra when interpreted by a trained physician yield information that may assist in diagnosis.

Device Story

The GE Signa® Excite 1.5T and 3.0T MR systems are superconducting magnetic resonance scanners. They acquire 2D and 3D images and spectra by detecting the spatial distribution of protons (hydrogen nuclei) using magnetic resonance. The systems support 1, 4, 8, and 16 independent receive channels, with modular expansion capability in 16-channel increments. The device is operated by trained professionals in clinical settings to produce high-resolution anatomical images and spectroscopic data. These outputs are interpreted by physicians to assist in clinical diagnosis. The systems are designed for high signal-to-noise ratios and short scan times.

Clinical Evidence

Bench testing only. The systems were evaluated against IEC 60601-1 International Medical Equipment Safety Standard and IEC 60601-2-33 Particular Requirements for Safety of Magnetic Resonance Equipment for Medical Diagnosis.

Technological Characteristics

Superconducting magnet operating at 1.5T and 3.0T. Supports 1, 4, 8, 16 independent receive channels with modular expansion. Acquires 2D/3D images in sagittal, coronal, axial, oblique, and double oblique planes. Supports multinuclear spectroscopy. Complies with IEC 60601-1 and IEC 60601-2-33 standards.

Indications for Use

Indicated for use as a diagnostic imaging device for the entire body, including head, neck, TMJ, spine, breast, heart, abdomen, pelvis, joints, prostate, and musculoskeletal regions. Produces axial, sagittal, coronal, and oblique images and spectra to assist in diagnosis. For use by trained physicians.

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.

Predicate Devices

• Signa® 1.5T Infinity MR system (K013636)
• Signa® 3.0T Infinity with Excite Technology MR System (K030874)
