What is the recommended CT dose limit for c-spines?
There are limits on the amount of radiation that workers can receive annually, or that a member of the public can receive when they visit a facility that uses radiation as a part of its business (for example, a medical clinic). However, a patient is allowed to receive any amount of radiation that an authorized medical professional deems necessary to image or treat the patient's condition. Many radiological imaging procedures use "automatic exposure control" which delivers the precise amount of radiation needed to obtain a high-quality image with the appropriate radiation dose. This is similar to the way that photographic cameras work. If automatic exposure control is not available, then the technologist relies on their training and experience to select the correct radiation dose needed to produce a high-quality set of pictures. In modern CT scanners, a Dose Report is produced for every CT examination, which describes the radiation dose that was used to complete that exam.
