barium sulfate
inorganic compound
Lithopone
Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide ("zinc white"), zinc sulfide, and white lead.
diatrizoic acid
Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging. This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan). It is given by mouth, injection into a vein, injection into the bladder, through a nasogastric tube, or rectally.
iohexol
Iohexol, sold under the trade names Omnipaque and Iodaque among others, is a contrast agent used for X-ray imaging. This includes when visualizing arteries, veins, ventricles of the brain, the urinary system, and joints, as well as during computed tomography (CT scan). It is given by mouth, injection into a vein, or into a body cavity.

Diodone is a radiocontrast agent that was used in urography. It was usually formulated as a salt with diethanolamine.
Barium sulfate suspension
contrast agent used during X-rays
iopromide
Iopromide is an iodinated contrast medium for X-ray imaging. It is marketed under the name Ultravist which is produced by Bayer Healthcare. It is a low osmolar, non-ionic contrast agent for intravascular use; i.e., it is injected into blood vessels.
propyliodone
Propyliodone (INN, trade name Dionosil) is a molecule used as a contrast medium in bronchography. It was developed by a team at Imperial Chemical Industries in the late 1930s.
ioxitalamic acid
chemical compound
iocarmic acid
chemical compound
methiodal sodium
Methiodal is a pharmaceutical drug that was used as an iodinated contrast medium for X-ray imaging. Its uses included myelography (imaging of the spinal cord); for this use, cases of adhesive arachnoiditis have been reported, similar to those seen under the contrast medium iofendylate.
metrizoic acid
chemical compound
iomeprol
Iomeprol, sold under the brand name Imeron among others, is a medication used as a radiocontrast agent in X-ray imaging.

iodipamide
Adipiodone (INN, or iodipamide; trade names Cholografin and Biligrafin) is a pharmaceutical drug used as a radiocontrast agent in X-ray imaging. It was introduced in the 1950s.
iodoxamic acid
chemical compound
iopydol
Iopydol is a pharmaceutical drug used as a radiocontrast agent in X-ray imaging.
iotrolan
Iotrolan (trade name Isovist) is an iodine-containing radiocontrast agent, a substance used to improve the visibility of body structures on images obtained by X-ray techniques.
ioxaglic acid
chemical compound
iobitridol
Iobitridol (trade name Xenetix) is a pharmaceutical drug used as an iodine-based radiocontrast agent in X-ray imaging. It is injected into blood vessels, joints, or body cavities such as the uterus, and filtered out by the kidneys. Its most common adverse effect is nausea. Severe allergic reactions are rare.
ioglycamic acid
chemical compound
metrizamide
Metrizamide is a non-ionic iodine-based radiocontrast agent. It is also a density gradient medium for the centrifugation of biological particles.
