X-ray / Computed Tomography
Bracco Contrast products for CT include a comprehensive range of contrast media that enhance visualization, patient compliance, and help you meet the needs of your patients.
One of the milestones in the history of modern medicine was the discovery of X-rays in 1895 by Wilhelm Conrad Roentgen. Their potential for diagnostic medicine was recognized immediately and diagnoses could be made on patients non-invasively. Two-dimensional X-ray imaging remained the basis of clinical radiology until 1972 when British engineer, Godfrey Hounsfield, invented computerized cross-sectional imaging with computed tomography (CT). CT imaging unveiled the mystery of the incidence and evolution of many diseases. It had a fundamental impact on medicine. In 1998, CT was revolutionized with the introduction of the first four-slice spiral CT scanners. This multidetector-row scanning transformed CT into a truly dynamic and fully three-dimensional imaging technique. Shortly after Roentgen discovered X-rays, investigations with radiopaque substances to lend contrast to body areas not otherwise visible with X-rays, identified iodine as the preferred radiopaque substance. Iodine remains to this day the preferred radiopaque substance in most X-ray and CT contrast agents. In the late 1920s, researchers focused on water-soluble contrast agents in an effort to improve the solubility, increase the iodine content, and decrease the toxicity of the existing radiographic contrast agents. In the 1950s, compounds were introduced that are still widely used today. They are known as tri-iodinated ionic contrast agents. Bracco markets a wide variety of ionic contrast agents which are still used today to enhance a variety of radiographic images in X-ray and CT. In 1974 the first nonionic water-soluble iodinated contrast agent was introduced but was later replaced in the early 1980s with the modern nonionic contrast agents. The lack of ionicity and resulting low osmolality of these compounds caused a major shift from ionic contrast agent use, to nonionic contrast agent use, in both X-ray and CT imaging.
