The biopsy plates allow access to the breast anatomy during biopsy procedures. No biopsy needles are included with, or packaged with the 3.0T HD Breast Array. The indications for use are the same as for standard MR Imaging. The 3.0T HD Breast Array is designed for use with the 3.0T Signa Excite MRI scanner, manufactured by General Electric Healthcare. ## Device Story 3.0T HD Breast Array is a phased-array, receive-only MRI coil; used for breast and axillary imaging and biopsy procedures. Device consists of a main base, coil chamber, sternum bridge, and lateral wings; houses eight coil elements within a rigid plastic housing. Operates as an accessory to the GE 3.0T Signa Excite MRI scanner. During biopsy, integrated plates provide lateral and medial access to breast anatomy. Device does not include biopsy needles. Radiologists or technicians operate the coil within an MRI suite; output is processed by the MRI scanner to generate diagnostic images. Benefits include optimized imaging at 3.0T field strength and facilitated biopsy access. ## Clinical Evidence Bench testing only. Testing performed to demonstrate that design modifications to the 3.0T HD Breast Array meet predetermined acceptance criteria. ## Technological Characteristics Phased-array, receive-only RF coil; 8-channel configuration. Materials: rigid, fire-rated plastic housing with high impact and tensile strength. Connectivity: dedicated interface for 3.0T Signa Excite MRI scanner. Form factor: base with coil chamber, sternum bridge, and lateral wings for breast positioning and biopsy access. ## 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. ## Predicate Devices - 1.5T Liberty 9000 8-channel Breast coil ([K041695](/device/K041695.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Section 514 of the Food, Drug and Cosmetic Act. | | | 7. Intended Use: | The 3.0T HD Breast Array is a receive-only RF coil, used for
obtaining MR images of the breast and axillary tissue. The biopsy
plates allow access to the breast anatomy during biopsy
procedures. No biopsy needles are included with, or packaged
with the 3.0T HD Breast Array. The indications for use are the
same as for standard MR Imaging. The 3.0T HD Breast Array is
designed for use with the 3.0T Signa Excite MRI scanner,
manufactured by General Electric Healthcare. | | | 8. Device Description: | The 3.0T HD Breast Array is a phased array, receive-only MRI
coil. The coil consists of a main supporting base with a coil
chamber in the middle section. A sternum bridge and two lateral
wings divide the chamber into two segments, one to receive each
breast. Each of the hollow coil segments houses four coil elements
that are insulated from the patient by a rigid plastic housing. The
coil housing is made of plastic materials, which are fire rated and
have high impact and tensile strength. The 3.0T HD Breast Array
is designed to offer optimized imaging capabilities and maximum
lateral and medial access to each breast for biopsy procedures. | | | 9. Marketed Device:
10. Comparison with Predicate: | 3.0T HD Breast Array
The 3.0T HD Breast Array is a modification of the existing cleared
1.5T Liberty 9000 8-channel Breast coil (K041695), with the main
difference being the coil has been retuned for operation in a 3.0T
magnetic field instead of a 1.5T field strength | | | 11. Summary of Studies: | Testing was performed to demonstrate that the design
modifications to the 3.0T HD Breast Array meet predetermined
acceptance criteria. | | {1}------------------------------------------------ #### Conclusion: It is the opinion of USA Instruments that the 3.0T HD Breast Array is substantially equivalent to the USA Instruments 1.5T Liberty 9000 8 channel Breast Array (K041695). Usage of the USA Instruments 3.0T HD Breast Array does not result in any new potential hazards. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the seal of the U.S. Department of Health & Human Services.
