Anesthetic management of patients undergoing magnetic resonance imaging (MRI) or computed tomography (CT) procedures poses unique risks and challenges due to the scanning equipment itself, communication difficulties, and an off-site location that is typically distant from the main operating room. In the CT suite, radiation exposure poses an additional hazard. In the MRI suite, the anesthesiologist must manage unique hazards due to the strong magnetic field, radiofrequency energy, and loud acoustic noise, as well as use specialized MRI safe equipment for anesthetic delivery and monitoring.

This topic will review anesthetic management of adults and children undergoing MRI or CT procedures. The principles and risks of MRI and CT imaging in adults and children are addressed in other topics:

(See "Principles of magnetic resonance imaging".)

(See "Radiation-related risks of imaging".)

(See "Approach to neuroimaging in children".)
