Abstract: The current study investigates the differences in the average doses used to perform the most common CT examinations of the neck and cervical spine at the Al – Makassed hospital in Jerusalem and its worldwide consistent medical centers regarding the application of the radiation protection optimization principle. The study uses a blended research approach. Thus, it fits into the observational and descriptive studies. It aims to assess the averages of the CT dose descriptors (CTDI and DLP), compare them with those established in various countries, and describe the application of radiation protection principles, especially the optimization principle (ALARA). Studies demonstrate accepted fluctuations in the number of the obtained CT examinations, according to the imaging facility examination storage for each examination, in which 87% of the total number of the cervical spine and (13%) of the Neck. The scan parameters (kvp), (MAs), scan length, and variations refer to the CT engineer’s selection or the protocol itself.
