Abstract：
:Computed tomography is often the first-line diagnostic imaging modality in the evaluation of patients with neurologic emergencies. A patient-centered approach to radiation dose management in emergent neuroimaging thus revolves around the appropriate use of computed tomography, including clinical decision support for ordering providers, thoughtful protocol design, the use of available technological advances in computed tomography, and radiation exposure monitoring at a population level. A multifaceted approach can help to minimize radiation exposure to individual patients while preserving diagnostic quality imaging.
