The purpose of this exhibit is to educate radiologists and technologists to properly identify and understand CT radiation dose parameters, and how to modify such parameters to optimize radiation dose during the performance of a diagnostic CT exam.
Dose sheets and CT images will be presented in quiz format. The scenarios will include:
Inappropriate kVp or quality reference mA parameter settings
Situations in which parameters should have been modified for patient considerations such as size
Longer than necessary scan length resulting in increased patient radiation exposure
Suboptimal patient positioning leading to increased radiation exposure
CT scanner parameters that exceed conventional thresholds
Suboptimal parameter adjustment resulting in improper ECG triggering or contrast bolus triggering
Optimizing CT protocols is an important responsibility for radiologists and technologists. An online quiz module can be an effective educational tool to simulate daily scenarios in which the radiologist and technologist must understand and modify scan parameters in order to decrease the amount of radiation necessary to produce diagnostic-quality CT exams.
