Quantitative distribution of iodinated contrast media in body computed tomography: data from a large reference cohort

ConclusionsDistribution of IC obtained from a large-scale cohort is provided. As significant differences between sexes and age groups were found, this should be taken into account when obtaining quantitative iodine concentrations and applying iodine thresholds.Key Points•Absolute iodine concentration showed a broad variation and differed between body mass index, age groups, and between the sexes in parenchymatous organs, lymph nodes, and vessels.•The iodine perfusion ratios did not show dependency on body mass index while significant differences between sexes and age groups persisted.•Provided guidance values may serve as reference when aiming to differentiate healthy and abnormal tissue based on iodine perfusion ratios.
