Center for Devices and Radiological Health This guidance provides performance criteria for magnetic resonance (MR) receive-only coils in support of the Safety and Performance Based Pathway. Under this framework, submitters (you) planning to submit a 510(k) using the Safety and Performance Based Pathway for MR receive-only coils will have the option to use the performance criteria proposed in this guidance to support substantial equivalence, rather than a direct comparison of the performance of the subject device to that of a predicate device.
