Gastrointest Endosc. 2007 Oct;66(4):757-61. doi: 10.1016/j.gie.2007.03.1049. 2010 Oct;72(4):905-6. doi: 10.1016/j.gie.2010.01.020. PRECAUTIONS 1. Endoscopically examine the lesion. The physical deflection and strength of attraction of endoclips: Resolution Clip, TriClip, QuickClip, and Ethicon Endo-surgery Clip were measured in different positions by using an MRI scanner at a field strength of 1.5 Tesla. Clips were selected for testing that represented the largest metallic sizes made from materials with the highest magnetic susceptibilities among 61 other similar implants. Gastrointestinal Endoscopy 2004;59:267-279. NIH 2003 Mar;24(3):463-71. Design: All commercially available endoclips are labeled as magnetic resonance imaging (MRI) incompatible. All of the clips were acceptable or safe at 1.5-Tesla insofar as there was no substantial magnetic field interactions or heating measured for these implants. Weishaupt, et al. Gill A, Shellock FG. Shellock FG. MRI safety guidelines are established by the MRI Safety Committee and apply to all clinical and research MRI systems operated at UCSF and SFVAHCS. Which clip? Surg Endosc. Therefore, patients that have the implants made from nonmagnetic or “weakly” magnetic materials listed in The List are not at risk for injury during MR procedures. Shellock FG. Main outcome measurements: To determine the compatibility of different endoclips with MRI. Vascular grafts frequently have clips or fasteners applied that may present problems for MR imaging because of the associated artifacts. It also can be used for hemostasis for prophylactic clipping to reduce the risk of delayed bleeding post lesion resection. BACKGROUND: Endoscopic clipping devices are now available for treatment of GI hemorrhage and microperforations. The radiopaque Resolution Clip is designed for hemostasis, endoscopic marking, closure and anchoring of jejunal feeding tubes. No data are available about the actual magnetic field strength at which endoclips are first deflected nor the clinical relevance of the magnetic fields on endoclips used in GI endoscopy. Results: I had a colonoscopy in August during which 2 polyps were removed. Epub 2015 Jun 20. 9. This could be harmful to the patient.”, QuickClip2 Long, HX-201LR-135L & HX-201UR-135L. MRI Safety and Compatibility Information MR conditional: Non-clinical testing has demonstrated the Resolution™ Clip is MR Conditional according to ASTM F2503. Shellock FG, Morisoli S, Kanal E.

Contact the Edwards Lifesciences Technical Support Department at 800-822-9837 (USA) or 949-250-2500 for any additional information regarding MRI safety … All commercially available endoclips are labeled as magnetic resonance imaging (MRI) incompatible. seen during upper endoscopy. Patients with nonferromagnetic versions of these implants may undergo MR procedures immediately after they are placed. 49, No. An investigation by Gill, et al. You may not be able to have an MRI while the clip is still in you. Brown MA, et al. A pig model and a small number of clips. Clip with Confidence. MRI Safety and Compatibility.

MR imaging and biomedical implants, materials, and devices: An updated review. The Long Clip HX-600-090L (Olympus Medical Systems Corporation) is indicated for placement within the gastrointestinal tract for the purpose of endoscopic marking, hemostasis, or closure of GI tract luminal perforations within 20-mm as a supplementary method. Endoclips for GI endoscopy. 2012;14:3-7. Gastrointest Endosc. This could be harmful to the patient.”. The QuickClip2 Long, HX-201LR-135L & HX-201UR-135L (Olympus Medical Systems Corporation) are indicated for placement within the gastrointestinal tract for the purpose of endoscopic marking, hemostasis, or closure of GI tract luminal perforations within 20-mm as a supplementary method.
