Interactions and heating time-course of cerebral aneurysm flow diverters during scanning at 7 Tesla

Motivation: Adverse interactions with static magnetic fields (e.g., displacement force and torque) and radiofrequency-induced heating during MRI have been resolved for 3T MR systems, but have yet to be assessed for 7T MRI. Goal(s): The present study aimed to assess displacement force and torque in the 7T static magnetic field and to clarify radiofrequency-induced heating during 7T MRI for two types of FDs. Approach: This study was conducted based on the ASTM standards. Results: Magnetic field interactions and heating on FDs during 7T MRI are acceptable from a safety perspective. Impact: This study based on ASTM standards showed magnetic field interactions and heating on FDs during 7T MRI are acceptable from a safety perspective.
