Intended Use

Intended use of the 3T 16ch Flex SPEEDER Coils is identical to that of routine MR imaging: specifically to produce diagnostic images of the upper and lower extremities, chest, abdomen, pelvis, head, neck, and spine. Use of the device in conjunction with an MRI scanner is unchanged.

Device Story

The NeoCoil 3T 16ch Flex SPEEDER Coils are receive-only phased array MRI coils designed for high-resolution imaging of various anatomical regions, including extremities, torso, head, neck, and spine. The system comprises two flexible, detachable antennae that conform to patient anatomy to reduce motion artifacts. The coils are tuned to the proton precession frequency of a 3 Tesla magnetic field. Operated by trained clinicians in a clinical MRI environment, the device receives RF signals which are processed by the host Toshiba 3T MRI scanner to generate diagnostic images. The device features modified DC and RF chains for 3T compatibility and relocated preamplifier circuitry to improve signal stability. The output images assist physicians in clinical diagnosis. The device benefits patients by providing high-quality diagnostic imaging while accommodating diverse anatomical shapes.

Clinical Evidence

Clinical performance testing was conducted in accordance with FDA guidance for Magnetic Resonance Diagnostic Devices. The study evaluated the 3T 16ch Flex SPEEDER Coils (Large and Medium) across various anatomical regions in axial, sagittal, and coronal planes. No adverse events were reported. Performance was deemed adequate to support the indications for use, demonstrating equivalence to the predicate device.

Technological Characteristics

Receive-only phased array coil system; 3T magnetic field tuning; flexible/formable antenna design; ODU connectors for Toshiba 3T scanners. Complies with IEC 60601-1 (electromechanical safety), IEC 60601-1-2 (ESD), IEC 60601-2-33 (safety), ISO 10993-1 (biocompatibility), and NEMA MS-6 (SNR/uniformity).

Indications for Use

Indicated for use with Toshiba 3T Magnetic Resonance Scanners with ODU connectors to produce diagnostic images of the upper and lower extremities, chest, abdomen, pelvis, head, neck, and spine for interpretation by a trained physician.

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.
