Course Description
The goal of this video-based course is to introduce radiologic technologists (RTs) and other healthcare professionals to computed tomography (CT) imaging. This is an introductory course and will serve as a review of basic concepts in CT for seasoned RTs. This course will begin by reviewing the history of CT. Next, it will go on to explain the advantages and risks of performing a CT imaging study. The remainder of the course will discuss how a CT image is produced, the purpose of contrast media, CT procedures, and related cross-sectional images and associated pathologies.

Learning Objectives
After reviewing the content, the participant should be able to:

• SUMMARIZE the history of computed tomography (CT).
• OUTLINE the advantages and risks of using CT scan.
• EXPLAIN how a CT image is produced.
• EXPLAIN the purpose of contrast media.
• OUTLINE CT procedures and IDENTIFY cross-sectional CT images and some associated pathologies.
