The iodine-based dyes injected into a vein for most CT scans, and the drinks of iodine or barium that outline the gut. They make blood vessels, organs and many tumours stand out.
The WHO groups water-soluble low-osmolar X-ray contrast media under ATC V08AB, including iohexol, iopamidol, iopromide, ioversol, iodixanol, iomeprol and iobitridol. Labels in the United States cover CT of the head and body, angiography and urography; several carry boxed warnings against intrathecal use, and iohexol's warns to use only the concentrations recommended for intrathecal procedures. Iopromide's label also covers contrast-enhanced mammography. Oral agents outline the gut: barium sulfate drinks for CT of the abdomen, and water-soluble diatrizoate (Gastrografin) when barium could be dangerous.
Iodine and barium have high atomic numbers and absorb X-rays strongly, so tissues and spaces containing them appear bright; tumours with abnormal vessels enhance in characteristic phases after an intravenous injection.
The chalky drink swallowed before some CT scans and X-rays so the gullet, stomach and bowel show up clearly.
A drink of iodine-based dye used to outline the gut on X-rays and CT scans, especially when a leak or perforation is possible and barium would be unsafe.
A CT and angiography dye given into a vein or artery.
One of the commonest dyes used for CT scans, given into a vein, by mouth or in other ways depending on the scan.
A CT and angiography dye approved in the United States in 2024.
A CT and X-ray dye made by Bracco, sold for injection into a vein and, in a separate form, into the spinal fluid for myelography.
A CT dye given into a vein. In the United States it is also licensed for contrast-enhanced mammography, a breast X-ray taken after the dye to show cancers that ordinary mammograms can miss.
An X-ray dye put into the bladder through a catheter to outline the bladder and urethra.
A CT and angiography dye given into a vein or artery.
