With an expanding field of radiologic procedures and interventions, the pediatric anesthesiologist is being frequently called on to provide anesthetic coverage for children undergoing both invasive and noninvasive radiologic studies. Anesthetic involvement is frequently necessary in order to complete these pediatric radiologic procedures. The anesthesiologist can provide an invaluable service to the radiologists. The children in need of anesthesia can present both medical and anesthetic challenges. Providing anesthesia in the radiologic suites requires not only a familiarity with the procedures, but also careful and extensive planning and resources.
