Final answer:
The range of serum iodine concentration for adequate tissue opacification during contrast-enhanced CT exams is not provided in the reference material, and would typically be higher than normal serum concentrations. Accurate ranges can be found in clinical guidelines or product information for specific contrast agents.
Step-by-step explanation:
The range of serum iodine concentration for adequate tissue opacification during contrast-enhanced CT exams is typically at a much higher concentration than the normal concentration in plasma or serum, which is between 4 to 10 µg/100 ml. During a contrast-enhanced CT scan, the concentration of iodine used varies based on the type of scan and the specific contrast agent being used.
For instance, it's not uncommon for concentrations to be measured in mg/mL when it comes to iodine-based contrast agents. In the direct context of this question, precise values for adequate tissue opacification can vary, and it would be best to consult relevant clinical guidelines or product-specific information for the exact concentration required.
