Key Factors Governing Optimal Iodinated Contrast Enhancement in CT

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.
