Anatomic Regions: Vascular structures, soft tissue and musculoskeletal structures in the lower extremities (mid-abdomen to mid-foot) ## Device Story The Model 675GE-64 Peripheral Vascular Coil is a phased array MRI coil system consisting of a Lower Extremity Flexible Array (Model 665GE-64) and a Medium General Purpose Flex Coil (Model 538GE-64). Designed for use with GE Signa 1.5T MRI systems, the device captures radiofrequency signals from the patient's lower extremities. These signals are processed by the host MRI system to generate diagnostic images. Operated by radiologists or MRI technicians in clinical settings, the coil facilitates high-resolution imaging of vascular and musculoskeletal anatomy. The device does not alter the MRI system's safety parameters (static magnetic field, RF power, acoustic noise) or imaging performance metrics (SNR, uniformity, distortion). It provides clinicians with detailed anatomical visualization to support diagnostic decision-making. ## Clinical Evidence Bench testing only. The submission relies on performance comparisons demonstrating that the device does not alter the safety or imaging performance specifications of the GE Signa 1.5T MRI system. ## Technological Characteristics Phased array MRI coil system; compatible with GE Signa 1.5T MRI systems. Materials comply with UL 94 (flammability) and CPAI-84 (flame resistance). Electrical safety complies with UL 544 and IEC 601-1. Passive sensing device; no internal software or active processing algorithms. ## 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. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

After reclassification, the FDA's Center for Devices and Radiological Health released a draft guidance document for the content and review of Magnetic Resonance Diagnostic Device premarket notification submissions that offered clarification of these concerns. The following is a summary of the information contained within this premarket notification that addresses these concerns: The GE 1.5T Signa MRI system operated with the Medical Advances Peripheral Vascular Coil is substantially equivalent to the same system operated with the legally marketed predicate device listed in section 4.0, within the Class II definition of Magnetic Resonance Diagnostic Device with respect to the safety parameter action levels: ## Safety Parameters Maximum Static Magnetic Field: No change Rate of Magnetic Field Strength Change: No change RF Power Deposition: No change Acoustic Noise Levels: No change {2} ## Imaging Performance Parameters | Specification Volume: | No change | | --- | --- | | Signal-to-Noise Ratio: | No change | | Image Uniformity: | No change | | Geometric Distortion: | No change | | Slice Thickness and Gap: | No change | | High Contrast Spatial Resolution: | No change | ## General Safety and Effectiveness Concerns The device contains instructions for use. It includes indications for use, precautions, cautions, contraindications, warnings and quality assurance testing. This information assures safe and effective use of the device. ## Substantial Equivalence Summary The GE 1.5T Signa MRI system operated with the Medical Advances Peripheral Vascular Coil addressed in this PMN, has the same intended use and technological characteristics as the same system operated with the identified legally marketed predicate device. The use of this coil does not affect the GE Signa system safety parameter specifications. --- **Source:** [https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MOS/K964813](https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MOS/K964813) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
