Contrast media have been used in diagnostic imaging since the late 1800s and have evolved over the decades. Contrast media facilitate the interpretation of medical imaging by increasing the differences seen between body tissues displayed on the images. Through various mechanisms, contrast media influence a tissue or organ&s ability to absorb or reflect energy from electromagnetic radiation or ultrasound. These agents are commonly used with many imaging techniques including conventional radiography, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound.
