Program Summary:

Section 2, CT Imaging Physics, Patient care, Contrast Agents

In the Introduction to Reconstruction section the 6 steps of Reconstruction are enumerated & discussed. This discussion is followed by discussion of the 4 types of Data Acquisition Methodologies that include Axial, Helical, Scanography or Topography and Dynamic Scanning. Defining Image Quality is a discussion that introduces the CT operator controlled Performance Parameters and Influencing Factors and concludes with discussion that includes the definition and influencing factors for Spatial, Contrast & Temporal Resolution. Important CT artifacts are discussed and demonstrated. The Patient Care & Safety section begins with a relevant discussion concerning the importance of obtaining an accurate and inclusive Clinical History and differentiating Symptoms & Signs. A thorough discussion of factors important to achieve accuracy with Patient Review including history symptoms by physiologic system is included. Those questions important prior to contrast administration are also included. The discussion concludes with a definition of positive & negative contrast media, the categorization of contrast media according to ionicity and the introduction of important contrast terms such as osmosis, osmolarity and clearance.


With a minimum of 80% proficiency, participants, at the conclusion of the presentation, will be able to:

  • List and discuss the 6 steps of Reconstruction
  • List and discuss the 4 types of Data Acquisition
  • List and define the most important operator controlled CT Performance Parameters
  • Define and describe Spatial, Contrast & Temporal Resolution and their most important influencing factors
  • Identify the most prominent Artifacts seen in CT and state their remediation
  • Relative to patient history, define Signs versus Symptoms and cite examples of each
  • State the most important patient history questions regarding the introduction of IV contrast
  • Define and describe the essential elements of positive and negative contrast media
  • Define and describe the most important factors associated with patient reactions to IV contrast media
