These images and/or spectra when interpreted by a trained physician, yield information that may assist in diagnosis. ## Device Story Magnetic Resonance Diagnostic Device (MRDD) producing cross-sectional images and spectroscopic data (1H, 31P) of head, body, and extremities; utilizes RF receive-only coils and magnet bore; operated by clinicians in radiology settings. Features include patient comfort enhancements (forced air, observation camera, laser positioning), ceiling-suspended console with LCD display, and Compaq Alpha processor for high-speed reconstruction (40 images/sec). Supports real-time interactive imaging, diffusion/perfusion mapping (ADC, TTP, MTT), and vector ECG gating. Physician interprets output to assist in clinical diagnosis; device provides structural and functional anatomical information. ## Clinical Evidence No clinical data provided; bench testing only. Safety and effectiveness are established through comparison to the predicate device and adherence to NEMA, UL, and IEC 601 standards. ## Technological Characteristics MRDD system (0.5T, 1.5T, 1.6T configurations). Uses RF receive-only coils (e.g., Synergy Pediatric Coil). Processing via Compaq Alpha processor. Connectivity includes ceiling-suspended console with 20-inch LCD. Safety standards: NEMA, FDA MRDD guidance, UL, IEC 601. Software-based reconstruction and analysis. ## 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. ## Predicate Devices - Philips GYROSCAN NT Release 6 series ([K980645](/device/K980645.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
