Learning Objectives
Upon completion of this case, the participant will be able to:
- Understand how CTDI and DLP are used
- Understand the limitations in these values with different size patients
- Understand the method used to determine the Size Specific Dose Estimate (SSDE)
- Understand the limitations in the use of SSDE
Image Wisely encourages practitioners to optimize the amount of radiation used in
medically necessary imaging studies and to eliminate unnecessary procedures
