This video is designed to satisfy annual CT radiation dose education for CT technologists.  It begins with a brief history of radiography and CT.  The factors which affect radiation dose are described along with the biologic effects of radiation.  The metrics for measuring exposure and the estimation of radiation dose are explained.  Technical considerations for managing radiation dose to the patient are described.  Newer metrics for radiation dose estimates in CT, specifically size-specific dose estimates (SSDE) are explained.  Finally examples for monitoring and reporting patient dose are presented.

  • Describe the impact of the development of CT with regard to neuroimaging
  • List the technical parameters which affect CT dose
  • Describe the effect of CT dose on CT image quality
  • Define stochastic and deterministic effects
  • Describe several methods for reducing CT radiation dose
  • Define the various methods of estimating f CT radiation dose
  • Describe how software programs can be utilized in CT dose monitoring, tracking and reporting

The content of this CT Program is intended for healthcare professionals who work in the CT environment. These individuals include CT Technologists, Imaging Nurses, CT Researchers, and Others.  The Joint Commission and ACR require annual CT Radiation Dose education (just like with MR level 1 and level 2).  This will satisfy that requirement.

This program has been approved for 1.0 hour of Category A CE credit as designated by the Society for MR Radiographers & Technologists (SMRT) RCEEM. Please Note: This activity was previously offered within a combined CE Module and cannot be used again in this or any subsequent biennium if completed previously. Additionally, this activity may be available in multiple formats or from different sponsors. ARRT regulations state that an individual may not repeat an activity for credit if it was reported in the same or any subsequent biennium. Release Date: 2/03/2018 Expiration Date: 2/02/2020
