Adverse-event reports (MAUDE)

Read this first: MAUDE report counts cannot be used to compute incidence rates or compare device safety. Reporting is incomplete, duplicated, and spikes with publicity; there is no denominator of devices in use. The peer line shows reporting volume for the average device in the same FDA product code — a reporting baseline, not a risk measure.

No adverse-event reports are linked to this device.

2025-08-28Z-2661-2025Class IOpen, ClassifiedThere is a potential for an ice blockage to form or currently exist within the magnet venting system. In the event of a quench, helium gas may be unable to escape through the designed venting paths, leading to a pressure build-up within the helium containment system. This pressure build-up could ultimately rupture the helium containment system, potentially resulting in a helium leak into the scanning room.Distribution: Worldwide distribution - US Nationwide and the countries of United Arab Emirates, Armenia, Angola, Argentina, Austria, Australia, Azerbaijan, Bosnia and Herzegovina, Bangladesh, Belgium, Bulgaria, Bahrain, Brunei Darussalam, Brazil, Botswana, Belarus, Canada, Switzerland, Chile, China, Colombia, Cyprus, Czechia, Germany, Denmark, Algeria, Ecuador, Estonia, Egypt, Spain, Ethiopia, Finland, Faroe Islands, France, United Kingdom of Great Britian and Northern Ireland, Georgia, Greece, Hong Kong, Croatia, Hungary, Canary Islands, Indonesia, Ireland, Israel, India, Iran, Iceland, Italy, Jordan, Japan, Kenya, Korea, Kuwait, Kazakhstan, Lebanon, Sri Lanka, Lithuania, Luxembourg, Latvia, Morocco, Monaco, Moldova, Montenegro, Republic of North Macedonia, Myanmar, Mongolia, Macao, Malta, Maldives, Mexico, Malaysia, Mozambique, Nigeria, Netherlands, Norway, Nepal, New Zealand, Oman, Panama, Peru, Philippines, Pakistan, Poland, Portugal, Paraguay, Qatar, Reunion, Romania, Serbia, Russian Federation, Saudi Arabia, Sweden, Singapore, Slovenia, Slovakia, Senegal, Syrian Arab Republic, Thailand, Turkmenistan, Tunisia, Turkey, Trinidad and Tobago, Taiwan, Tanzania, Ukraine, Uganda, Uzbekistan, Viet Nam, Kosovo, South Africa.56 unitsclearance family
