CT for Technologists
Screening with CT

Format: Online Course
RT Credit: 2.75 ARRT Category A Credits 
Tuition: $41.25

The skill of the technologist is the single most important factor in obtaining high quality diagnostic images. A successful CT examination is the culmination of many factors under the direct control of the technologist.

CT for Technologists:– Screening with CT introduces the learner to the benefits of screening for coronary artery disease, lung cancer, colorectal cancer, and visceral fat. These important exams not only detect cancer early in the disease process, but assist both the physician and patient in the management of general health and lifestyle.

The unit is comprised of five chapters. To receive credit, you must complete all five chapters.

Chapter 1.   Coronary Artery Calcium Scoring

Chapter 2.   Coronary CT Angiography

Chapter 3.   CT Lung Cancer Screening

Chapter 4.   CT Measurement of Visceral Fat

Chapter 5.   Virtual Colonoscopy CT

After completing this material, the learner should be able to:

  • Describe atherosclerosis and its effect on the function of the coronary arteries
  • Explain how CT calcium scoring is performed and calculated
  • Discuss how the results of calcium scoring can impact patient management
  • Implement the patient preparation protocol for coronary CTA
  • Explain when and how prospective and retrospective triggering should be used
  • Describe the benefits of dual source CT in cardiac imaging
  • Compare the benefits and disadvantages of screening CCTA to stress testing and cardiac catheterization
  • Describe the types of artifact that appear on cardiac CTA and how to minimize or eliminate them
  • Discuss how to reduce radiation dose for CCTA and how it compares to other cardiac testing
  • List the risks for developing lung cancer
  • Discuss who should be screened for lung cancer
  • Implement a low-dose CT lung cancer screening protocol
  • Describe techniques for minimizing radiation dose
  • Discuss what makes low-dose CT an effective screening tool
  • Explain the risks of undergoing low-dose CT for lung cancer screening
  • Discuss the health risks associated with excess visceral fat
  • Explain how visceral fat builds up and how to minimize it
  • Implement CT protocols for visceral fat volume measurement
  • Explain when colon cancer screening should be performed
  • Prepare the patient to undergo virtual colonoscopy CT exam
  • Implement the scanning protocol for virtual colonoscopy
  • Discuss the value of virtual colonoscopy CT as a screening tool
  • Compare the advantages and disadvantages of virtual colonoscopy CT to conventional colonoscopy
