Since the inception of CT, its use in the emergency department (ED) has increased rapidly, raising concerns about potential risks of radiation exposure to patients, particularly the pediatric population. Therefore, radiologists should adhere to the ALARA principle, to ensure that imaging examinations are clinically indicated and to keep the radiation dose to a minimum. A substantial radiation dose reduction in abdominal and pelvic CT performed in emergency patients is achievable using the strategies described below while maintaining an acceptable level of diagnostic image quality.
