The Intravascular  Contrast Media

Development of Radiographic Agents

contrast mediaIn the year 1923, the first reported of an opacification it means "visible radiographically" of the urinary bladder with the use contrast media via intravenous injections. The contrast media used is a 10% sodium iodide solution which is used at this time for treatment of syphilis and excreted with urine. In 1928 a German reseachers synthesized a compound with a number of pyridine rings containing iodine to detoxify the iodine. The first tri-iodinated contrast media was developed the UROKON a sodium acetrizoate in 1952 this compound is from a mono-iodinated compound (pryridine) and developed further into di-iodinated compound and subsequently resulted in tri-iodinated contrast (Urokon). Sodium acetrizoate was based on a six carbon ring structure, tri-iodo benzoic acid, and was the precursor of all modern water soluble contrast media.
