Course Description
Dual-energy (DE) computed tomography (CT) and multienergy CT represent an emerging field in CT imaging and is moving quickly into mainstream CT imaging procedures. Numerous technical advances have taken place in recent years that incorporate this technology into standard imaging protocol, for which the most up-to-date information for radiologic technologists (RTs) is needed. This course will provide RTs with information on DECT and appropriate patient care, radiation protection practices, and procedures. The history of DECT as well as patient preparation prior to their imaging study, practices and procedures during the study, and patient post-care will be covered.  The contrast media used during DECT procedures including indications and contraindications and the responsibilities of the RT for patients, personnel, and the public in regards to radiation protection and safety are outlined. Image formation, evaluation, and archiving as well as the equipment associated with various procedures and the specific techniques and applications associated with DECT will be highlighted.

Learning Objectives
After completing this course, the participant should be able to:

• EXPLAIN the history of dual-energy computed tomography (CT).
• RESTATE pre-procedure, current, and postprocedure care as it pertains to the patient.
• IDENTIFY the contrast media used during dual-energy CT procedures including indications and contraindications.
• OUTLINE the principles of radiation protection, including the responsibilities of the radiologic technologist for patients, personnel, and the public.
• EXPLAIN image formation, evaluation, and archiving in dual-energy CT.
• EXPLAIN dual-energy CT and the equipment associated with various procedures.
• SUMMARIZE the various techniques and applications associated with dual-energy CT.
• COMPARE the advantages and disadvantages associated with dual-energy CT.
