Installation TimelineΒΆ

Over the past many months, we have been working diligently to finalize agreements between UCSD and the contractor selected to complete most of the work related to the removal of the current GE MR750 (3T East) and the installation of the new Siemens 3T Magnetom Prisma.

While this process has taken longer than anticipated, we are very pleased to announce that agreements between UCSD and the general contractor have been finalized and we have a clear timeline of install-related events.

The removal of the GE MR750 in 3T East will begin the week of 5/24/21. We may need to limit 3T East access as early as 5/17/21. The final 3T East access restriction date will be sent to active 3TE projects as we approach the ramp-down/removal date.

The Siemens Prisma will be delivered the week of 6/21/21. After installation, construction, testing and QA of the system are completed, we expect that the Prisma will be available to the user community around the 3rd week of August 2021.

At this point, active 3T East projects should have a transition plan in place (either resuming imaging on the Prisma when it is available or moving an existing study to 3T West). Over the past several months, we have finalized software license agreements between UCSD and several outside institutions which will allow us to run a number of well-established and validated protocols on the new Prisma.

If you want to discuss transition options in the context of the current installation schedule, please contact Aaron Jacobson (

The 3T West GE MR750 will remain fully operational and will be available to researchers who prefer to maintain their active projects on a GE system. We expect to announce a tentative long-term upgrade schedule for the 3TW scanner in about a year or two.

We appreciate your patience and understanding as we strive to make the most current equipment and resources available to the research community.
