Intended Use

Magnetic resonance imaging (MRI) of the musculoskeletal structures, soft tissue and vascular structures of the lower extremities.

Device Story

Model 475 8 Channel T/R Phased Array Lower Extremity Coil; accessory for GE and Siemens 1.5T and 3.0T MRI systems. Device captures RF signals from lower extremity anatomy; transforms signals into 2D/3D images (proton density, T1/T2 weighted, time of flight, phase contrast). Used in clinical radiology settings; operated by MRI technicians/radiologists. Output viewed on MRI system console; assists clinicians in diagnostic assessment of musculoskeletal/vascular pathology. Provides 3x improvement in signal-to-noise ratio in peripheral regions compared to predicate; supports fast imaging protocols.

Clinical Evidence

Bench testing only. Comparison of imaging performance parameters (FOV, SNR, image uniformity, geometric distortion, slice thickness/gap, high contrast spatial resolution) against predicate device. Results show 3x improvement in SNR in peripheral regions; no change in other performance metrics.

Technological Characteristics

8-channel T/R phased array coil; compatible with 1.5T and 3.0T MRI systems. Materials comply with UL 94 flammability standards. Safety compliant with UL 2601-1 and IEC 601-1. Form factor designed for lower extremity imaging.

Indications for Use

Indicated for MRI of musculoskeletal, soft tissue, and vascular structures of the lower extremities.

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.

After reclassification, the FDA's Center for Devices and Radiological Health (CDRH) released a draft guidance document for the content and review of Magnetic Resonance Diagnostic Device premarket notification submissions that offered clarification of these concerns. Due to considerable technological advances in MRDDs, CDRH issued an updated guidance document on November 14, 1998. The following is a summary of the information contained within this premarket notification that addresses these concerns: The GE and Siemens 1.5T and 3.0T MRI systems, operated with the Medical Advances 8 Channel T/R Phased Array Lower Extremity Coil, are substantially equivalent to the GE Signa 1.5T system operated with the legally marketed predicate devices listed in scction 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 due to coil | |-----------------------------------------|-----------------------| | Rate of Magnetic Field Strength Change: | No change due to coil | | RF Power Deposition: | Improved | | Acoustic Noise Levels: | No change due to coil | | Biocompatibility: | No change | {2}------------------------------------------------ # Imaging Performance Parameters | Specification Volume: | 15-16 cm typical FOV all planes<br>(submitted device) vs. 15-20 cm<br>typical FOV all planes (predicate<br>device) | |-----------------------------------|--------------------------------------------------------------------------------------------------------------------| | Signal-to-Noise Ratio: | 3 Times Improvement over predicate<br>device in peripheral regions | | Image Uniformity: | No change | | Geometric Distortion: | No change | | Slice Thickness and Gap: | No change | | High Contrast Spatial Resolution: | No change | | Fast Imaging Protocol Compatible: | Yes | ## 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 and Siemens 1.5T and 3.0T MRI systems operated with the Medical Advances 8 Channel T/R Phased Array Lower Extremity Coils addressed in this Pre-Market Notification, have the same intended use and technological characteristics as the GE Signa 1.5T system operated with the identified legally marketed predicate device. The use of these coils does not affect the GE or Siemens 1.5T and 3.0T system safety parameter specifications. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the seal of the U.S. Department of Health & Human Services.
