Evaluation performed against IEC 601-2-33 International medical equipment safety standard for Magnetic Resonance Systems. Software functionality confirmed. ## Technological Characteristics Software-based imaging technique; modification to Fast Gradient Echo pulse sequence; integrates Infusion Advisor scan; operates within Signa Horizon MR system architecture. ## 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 - Signa Horizon HiSpeed MR System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Box 414, W-709 Milwaukee, WI 53201 USA # SUMMARY OF SAFETY AND EFFECTIVENESS - This 510(k) summary of safety and effectiveness information is submitted in accordance with the requirements of 21 CFR Part 807.87(h). - **Identification of Submitter** Larry A. Kroger, Ph.D., 414-544-3894, August 16, 1996 - **Identification of the Product** SmartPrep IA Manufactured by: GE Medical Systems 3200 N. Grandview Blvd. Waukesha, WI 53188 - **Marketed Device** The SmartPrep IA Option is a modification to the currently marketed Signa Horizon MR Systems. - **Device Description** The SmartPrep IA Option is an optional imaging technique that results in a scan acquisition being triggered off of the arrival of a user injected bolus of contrast agent at a prescribed volume of interest. - **Indications for Use** SmartPrep IA option enables breath hold studies and trigger acquisition based on timing related to the arrival of a user injected exogenous contrast agent bolus. - **Comparison with Predicate** The SmartPrep IA Option is substantially equivalent to the currently marketed Signa Horizon HiSpeed MR System. The Fast Gradient Echo pulse sequence is modified by the insertion of an Infusion Advisor scan. - **Summary of Studies** The SmartPrep IA Option was evaluated to the IEC 601-2-33 International medical equipment safety standard for Magnetic Resonance Systems. Evaluation testing confirmed the functionality of the software. - **Conclusions** It is the opinion of GE that the SmartPrep IA Option is substantially equivalent to the currently marketed Signa Horizon Fast Gradient Echo pulse sequence. The option does not result in any new potential hazards. --- **Source:** [https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/LNH/K963429](https://fda.innolitics.com/submissions/RA/subpart-b%E2%80%94diagnostic-devices/LNH/K963429) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
