Anesthesia for MRI and CT

  • Gregory E. R. WellerEmail author


Magnetic resonance imaging (MRI) and computed tomography (CT) are advanced imaging technologies that offer unique diagnostic options for our patients. Due to the high clinical utility of these modalities, the demand for these scans is surging, and these scanner suites are increasingly busy at all hours. Many patients needing MRI or CT scans will require anesthesia services, due to young age, disability, developmental delay, pain, or claustrophobia. MRI and CT locations are potentially challenging environments in which to provide safe anesthetic patient care, due to their remote locations and unique hazards such as strong magnetic fields, ionizing radiation, thermal injuries, and contrast agents. This chapter presents background concepts, safety guidelines, and practical anesthesia options that will facilitate safe and efficient anesthetic care of pediatric and adult patients in these unusual imaging environments. Table 25.1 provides a summary of anesthesia considerations in patients undergoing MRI and CT imaging.
