Intended Use
To be used in conjunction with 1.5T GE HD series Magnetic Resonance scanners to produce diagnostic images of the chest, abdominal, and pelvic regions that can be interpreted by a trained physician.
Device Story
Multi-element phased array receive-only MRI coil; 16-channel configuration; consists of anterior (11 antennas) and posterior (5 antennas) housings. Anterior housing is rigid centrally and flexible laterally to wrap around patient; posterior housing is rigid. Antennas positioned with overlap to cancel mutual coupling; pre-amplifier decoupling used. Active and passive transmit decoupling circuits (diodes) ensure safety by switching to high impedance during RF transmit. Used in clinical MRI settings; operated by MRI technicians/radiologists. Provides diagnostic images of chest, abdomen, and pelvis to physicians for clinical interpretation. Benefits include increased lateral coverage (60 cm) compared to predicate, facilitating improved diagnostic imaging.
Clinical Evidence
Bench testing only. SNR and image uniformity testing performed to support substantial equivalence. No clinical data provided.
Technological Characteristics
16-channel phased array receive-only MRI coil. Materials: hard plastic housings, foam padding. Connectivity: cable interface to GE Healthcare 1.5T Signa Excite MRI scanner. Safety: active (diode-based) and passive (crossed-diode) transmit decoupling circuits. Standards: IEC 60601-1, IEC 60601-2-33, NEMA MS-6.
Indications for Use
Indicated for patients requiring diagnostic MRI imaging of the chest, abdominal, and pelvic regions using 1.5T GE HD series scanners. No specific age or gender contraindications stated.
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: | The NeoCoil 1.5T 16-Channel Cardiac-Abdominal-Pelvic Array Coil is a multi-<br>element phased array receive only coil used for obtaining diagnostic images of<br>the chest, abdominal, and pelvic regions in Magnetic Resonance Imaging<br>Systems. Compared to predicate device, the submitted device offers greater<br>lateral coverage (60 cm v. 42 cm). | | | |
| | The submitted device consists of two dependent housings; an anterior and a<br>posterior. The anterior housing consists of 11 antennas. It is rigid in the middle,<br>below the covers, and laterally flexible to permit it to wrap about the patient. The<br>posterior consists of 5 antennas. It is made of a hard plastic housing. A single<br>cable connects the posterior housing to the junction box, which provides the<br>interface with the anterior housing. The junction box provides the inter- | | | |

| connection for the anterior and posterior housings, which are mutually<br>dependant, and the GE Healthcare 1.5T Signa Excite MRI scanner. | |
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| The antennas are uniquely positioned with the appropriate overlap to cancel out<br>mutual coupling effects from adjacent antennas. Pre-amplifier decoupling<br>reduces any remaining coupling between the antennas. | |
| The posterior housing is covered with a padded surface, of the same foam<br>material as the anterior housing (flexible region). Hospital gowns, sheets, and/or<br>patient street clothing separate the patient from direct contact with the coil and<br>housing materials. | |
| The flexible portion of the anterior secures, about the patient, to the posterior with<br>the provided straps. The posterior housing nests securely in the MRI scanner<br>patient table. | |
| To ensure safety, each antenna is equipped with active and passive transmit<br>decoupling circuits. Active decoupling is achieved via diodes that receive signals<br>from the scanner to turn the coil to a high impedance state during system RF<br>transmit. Crossed diodes are installed on each antenna acting as passive<br>switches. These passive switches provide additional safety in case the active<br>circuitry does not receive signal from the scanner. | |
| Predicate Device: | IGC-Medical Advances Inc, Model 558GE-64 Torso Array Coil (K041185). |
| Comparison to Predicate: | It is our opinion that the NeoCoil 1.5T 16-Channel Cardiac-Abdominal-Pelvic<br>Array Coil in this submission is substantially equivalent to the previously cleared<br>IGC-Medical Advances Inc, Model 558GE-64 Torso Array Coil (K041185). |
| Summary of Studies: | In all material respects, the NeoCoil 1.5T 16-Channel Cardiac-Abdominal-Pelvic<br>Array Coil is substantially equivalent to the referenced predicate device. SNR<br>and image uniformity testing was performed which support the conclusion that the<br>submitted device satisfies design objectives. |
| Conclusion: | The NeoCoil 1.5T 16-Channel Cardiac-Abdominal-Pelvic Array Coil is<br>substantially equivalent to the predicate device. Use of the NeoCoil 1.5T 16-<br>Channel Cardiac-Abdominal-Pelvic Array Coil does not result in any new potential<br>hazards and does not alter the safety of the MRI scanner. |

Dear Mr. Lehtonen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
