Findings show personalized iodine delivery rate protocols improve coronary enhancement, suggesting a new CT angiography approach.
Question Virtual mono-energetic images lead to low iodine delivery rate settings, but the impact on coronary enhancement is not clear. Findings An iodine delivery rate-based injection protocol implementing personalized contrast volume dilutions with set injection duration and high injection rate improved coronary enhancement. Clinical relevance Iodine delivery rate fine-tuning is a promising approach for coronary CT angiography with low iodine volumes. High injection rates provide more accurate and precise coronary enhancement.
