The serum iodine concentration that is considered adequate for tissue opacification is typically within the range of 2-8 mg/mL. This concentration allows for sufficient contrast between the vascular structures and surrounding tissues when imaging, particularly in computed tomography (CT) scans. At this level, iodine helps to enhance the visibility of various tissues, enabling radiologists to discern different anatomical features more clearly.

Iodine is an effective contrast agent due to its high atomic number, which significantly increases its radiopacity. For optimal imaging, maintaining the serum iodine concentration within this specific range ensures that there is enough contrast without causing potential adverse effects or overwhelming the body’s processing of the contrast agent. This range is generally determined through clinical experiences and studies which have established it as effective for various clinical imaging scenarios.

Using concentrations outside this range may result in inadequate opacification or increased risk of complications, reminding practitioners of the importance of choosing the appropriate contrast amount for effective imaging outcomes.
