The carotid coil is a receive-only coil, used for high resolution imaging of the bifurcation of the carotid artery in 1.5T and 3T General Electric, Siemens and Philips Magnetic Resonance Imaging (MRI) systems. Nucleus Excited: Proton 1H Anatomic regions: Carotid. The Carotid Coil is used for obtaining diagnostic images of carotid in magnetic resonance imaging systems. These images, when interpreted by a trained physician, yield information that may assist in diagnosis.
Carotid Coil is a phased array, receive-only coil. It consists of eight elements optimized for high signal-to-noise ratio. Semi-flexible design makes the coil reliable and comforts the patient. The enclosure, which may contact the patient, is made up of biocompatible material.
The provided document is a 510(k) Summary for a Magnetic Resonance Diagnostic Device, Carotid Coil. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study of its clinical performance against specific acceptance criteria for diagnostic accuracy.
Therefore, many of the requested items (e.g., acceptance criteria for diagnostic performance, sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, ground truth for test/training set, training set sample size) are not applicable or not provided in this type of submission document, as it is a submission for a medical device (coil) used for imaging, not a diagnostic algorithm.
Here's a breakdown of what can be extracted from the document:
1. Table of Acceptance Criteria and Reported Device Performance
This document does not outline specific acceptance criteria for diagnostic performance (e.g., sensitivity, specificity, accuracy) of a device that interprets images. The "performance tests" mentioned refer to technical parameters of the coil itself.
| Acceptance Criteria (Technical) | Reported Device Performance (Technical) |
|---|---|
| Bio-compatibility tests | Complies with ISO 10993-5 and ISO 10993-10 |
| IEC60601-1 compliance tests | Complies with UL 60601-1 |
| Safety and Effectiveness | Proved safe and effective by performance tests, biocompatibility tests, and IEC60601-1 compliance tests; substantially equivalent to predicate device. |
2. Sample Size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable / Not Provided. This document describes a physical medical device (an MRI coil), not a diagnostic algorithm that processes data. Therefore, there is no "test set" in the context of diagnostic performance evaluation. The "performance tests" refer to the engineering and technical performance of the coil.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not Applicable / Not Provided. See point 2.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable / Not Provided. See point 2.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. This is not a study of an AI or diagnostic algorithm, but a physical MRI coil. An MRMC study would not be relevant here.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This is a physical MRI coil, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- Not Applicable / Not Provided. The "ground truth" concept as applied to diagnostic algorithms is not relevant for this submission about an MRI coil. The "ground truth" for the coil's performance would be its technical specifications verified by engineering tests.
8. The sample size for the training set
- Not Applicable / Not Provided. This is a physical MRI coil, not a machine learning algorithm.
9. How the ground truth for the training set was established
- Not Applicable / Not Provided. See point 8.

Dear Mr. Chen:
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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of
{4}------------------------------------------------
medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
