project description

The project involved the renovation of the existing MRI suite within the 2nd floor RR wing of University of Washington Medical Center. The existing MRI machine was replaced and the supporting patient prep areas, MRI control room and manager’s offices were remodeled. The new 3T MRI machine is a much more powerful replacement with the ability for greater imaging resolution and penetration.  A domestic cold water back up system was installed to automatically switch MRI cooling water from chilled water to domestic cold water when it was determined that chilled water was not available for cooling.
