Depending on the region of interest, contrast agents may be used. These images when interpreted by a trained physician yield information that may assist in diagnosis. The MAGNETOM C! may also be used for imaging during interventional procedures when performed with MR compatible devices such as, in room display and MR safe biopsy needles. Disclaimer: Utility of contrast enhanced breast MRI for the detection of breast masses has not been documented and is thus not indicated. ## Device Story MAGNETOM C! is an open, whole-body MRI scanner; produces transverse, sagittal, coronal, and oblique cross-sectional images of head, body, or extremities. Input: magnetic resonance signals; output: diagnostic images for physician interpretation. Used in clinical settings for diagnostic imaging and interventional procedures (e.g., biopsies) with MR-compatible tools. Modifications include updates to RF infrastructure, signal unit, filter plate, gradient amplifier, physiological measurement unit, measurement/reconstruction system, magnet temperature unit, patient table control, power distribution, external field interference shielding, and cooling system. System provides high-resolution imaging and reduced scan times; assists physicians in clinical diagnosis. ## Clinical Evidence Bench testing only. Performance evaluated against NEMA standards for signal-to-noise ratio, image uniformity, geometric distortion, high-contrast spatial resolution, and slice thickness. No clinical data provided. ## Technological Characteristics Open, whole-body MRI scanner. Modifications include RF infrastructure, RF signal unit, gradient amplifier, and integrated cooling system. Conforms to NEMA standards for performance measurement and IEC standards for safety. Software updated to support hardware modifications. ## 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 - Siemens MAGNETOM 1.5T ESSENZA ([K071925](/device/K071925.md)) - Siemens MAGETOM 0.35 T C !

Safety and Effectiveness Information Supporting Substantial Equivalence. #### Intended Use The MAGNETOM C! is indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, and that display the internal structure and/or function of the head, body, or extremities. Depending on the region of interest, contrast agents may be used. These images when interpreted by a trained physician yield information that may assist in diagnosis. The MAGNETOM C! may also be used for imaging during interventional procedures when performed with MR compatible devices such as, in room display and MR safe biopsy needles. Disclaimer: Utility of contrast enhanced breast MRI for the detection of breast masses has not been documented and is thus not indicated. ### Device Description The MAGNETOM C! system is an open, whole body scanner designed to support improved higher resolution imaging and shorter scan times, which was described in premarket notification K043030 which received FDA clearance on December, 10, 2004. Siemens intends to modify the RF Infra Structure, RF Signal Unit, Filter Plate, Gradient Amplifier, Physiological Measurement Unit, Measurement and Reconstruction System, Magnet Temperature Unit, Patient Table Control, Power Distribution System, External Field Interference, Integrated Cooling System and software update for the existing MAGNETOM C! Magnetic Resonance System. #### Substantial Equivalence Siemens believes that, within the meaning of the Safe Medical Device Act of 1990, the MAGNETOM C!, which is configured with modified hardware and software, is substantially equivalent to the following cleared medical devices, which offers the same applications and handling: | Predicate Device Name | FDA Clearance
