Sagittal, coronal and oblique planes may be imaged. MRI images produced by the ISAAC system reflect the spatial distribution of the density of hydrogen nuclei (protons), spin-lattice relaxation time (T1), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in determining an diagnosis. ## Device Story ISAAC 1.5 T MR System is a whole-body superconducting magnetic resonance imaging device. It utilizes a 1.5 T magnet, actively shielded gradient coils, and various pulse sequences to acquire MR signals. System includes transmit/receive head and body coils, plus receive-only specialty coils (knee, shoulder, neck, wrist, CTL). Operates in Normal Operating Mode for static field, dB/dt, and SAR per IEC 601-2-33. Acoustic noise levels comply with IEC standards. Images represent spatial distribution of hydrogen nuclei density, T1, T2, and flow. Used in clinical settings by trained physicians to assist in diagnostic decision-making. ## Clinical Evidence No clinical data. Substantial equivalence is supported by bench testing to NEMA performance standards and comparison of technological characteristics to predicate devices. ## Technological Characteristics 1.5 T superconducting magnet; actively shielded gradient coils; transmit/receive head/body coils; receive-only specialty coils. Operates in Normal Operating Mode per IEC 601-2-33. Acoustic noise < 99 dBA. Connectivity and software architecture not specified beyond standard MRI diagnostic imaging functionality. ## 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 Symphony ([K971684](/device/K971684.md)) - USA Instruments knee coil ([K971246](/device/K971246.md)) - USA Instruments shoulder coil ([K010946](/device/K010946.md)) - USA Instruments neck coil ([K964531](/device/K964531.md)) - USA Instruments wrist coil ([K972205](/device/K972205.md)) - USA Instruments CTL coil ([K982340](/device/K982340.md)) - USA Instruments CTL coil ([K980157](/device/K980157.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Inc. 104-10, Mun-Ji-Dong Yu-Seong-Gu, TaeJon KOREA Telephone: +82-42-863-6341 FAX No.: +82-42-863-6343 Contact: Henry Jang, Prepared: January 16, 2002 #### LEGALLY MARKETED PREDICATE DEVICES A. The CHI 1.5 T MR System is substantially equivalent to the Siemens Magnetom Symphony. The applicant believes that the device now called the Symphony is the same as the Siemens Magnetom Project 047, cleared by FDA as K971684 on August 5, 1997. In regard to the six receive-only specialty coils, they are substantially equivalent to the similar coils manufactured by USA Instruments. These were cleared for marketing under the following 510(k)s: K971246 (knee coil), K010946 (shoulder coil), K964531 (neck coil), K972205 (wrist coil), K982340, and K980157 (CTL coil). #### DEVICE DESCRIPTION B. The ISAAC 1.5 T MR System is a new clinical whole-body MR system, utilizing a superconducting magnet operating at 1.5 T. A variety of pulse sequences are available as described in Section II. The system is provided with transmit/receive head and body coils, along with several receive-only specialty coils. The system utilizes an actively shielded gradient coil. In regard to saffety, the system always operates in the Normal Operating Mode for static field level, dB/dt and SAR, according to the proposed revision of the IEC 601-2-33 standard. The acoustic noise is well within the 99 dBA limit specified in the IEC standard. {1}------------------------------------------------ #### INTENDED USE C. The ISAAC 1.5 T MR System is a 1.5 T whole-body magnetic resonance imaging (MRI) system intended for general diagnostic use. Sagittal, coronal and oblique planes may be imaged. MRI images produced by the ISAAC system reflect the spatial distribution of the density of hydrogen nuclei (protons), spin-lattice relaxation time (T1), spin-spin relaxation time (T2), and flow. When interpreted by a trained physician, these images provide information that can be useful in determining an diagnosis. #### SUBSTANTIAL EQUIVALENCE SUMMARY D. The ISAAC 1.5 T MR System is a medical device, and it has the same indications for use and target population as the legally marketed predicate device. The ISAAC 1.5 T MR System has the same technological characteristics as the predicate devices. A comparison of the descriptive characteristics may not be sufficiently precise to assure substantial equivalence, so for those characteristics, performance data are provided to assure equivalence. These data do, in fact, demonstrate equivalence. #### E. TECHNOLOGICAL CHARACTERISTICS The technological characteristics of the ISAAC 1.5 T MR System are the same as for the predicate device. #### F. TESTING Testing to the appropriate NEMA performance standards was carried out and reported in this 510(k). #### G. CONCLUSIONS This pre-market notification has demonstrated Substantial Equivalence as defined and understood in Sections 513(f)(1) and 513(i)(1) of the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health. {2}------------------------------------------------ ### DEPARTMENT OF HEALTH & HUMAN SERVICES Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 ## APR 2 5 2002 Chi.
