[1] Contrast agents absorb or alter external electromagnetism or ultrasound , which is different from radiopharmaceuticals , which emit radiation themselves.
Iodinated 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.
Paradoxical effects, such as increased activity, can occur especially in children and older people. [16] There is evidence of risk when used during pregnancy but no evidence of harm with a single dose during breastfeeding. [17] [18] Midazolam was patented in 1974 and came into medical use in 1982.
