WebInteresting, each iodinated contrast media caused the appearance of an abnormal peak in the alpha-2-zone of the electropherogram. All peaks had the same form and location as the extra peak found in electropherograms of patients who are infused with contrast agents. These findings were confirmed in other following investigations (28-30). WebIodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
