Hospitals are complex buildings and design solutions should fulfil functionalities to enable accurate diagnosis, treatment, and care. However, scientific results are seldom the basis for the design solution choices. Magnetic resonance imaging facilities require concrete structures fulfilling high requirements on vibration isolation to ensure diagnostic accuracy. The aim of the studies was to compare evidence from the literature to the chosen solutions in eight newly designed magnetic resonance imaging facilities. The conclusions are that there is insufficient scientific evidence for which structural configurations fulfil vibration requirements of MRI facilities, while those found were only partially implemented in recent designs.
