Key Factors Governing Optimal Iodinated Contrast Enhancement in CT

RadioGraphics (RSNA)Jul 1

This RadioGraphics review categorizes factors affecting CT contrast enhancement into scalar (tube potential, iodine concentration), temporal (cardiac output, injection rate), and sampling (scan delay, duration) parameters, providing a framework for protocol optimization to avoid…

  • This is an educational review, not an original research study; it synthesizes established physics and physiology into a practical three-category model (physics-based, patient-related, contrast protocol-based).
  • Improper contrast enhancement is a primary driver of repeat CT examinations or those with limited diagnostic utility.
  • The review lacks new empirical data, being a conceptual framework for teaching and protocol design.
