Iobitridol is a contrast medium used for intravenous urography, cerebral computed tomography, computed tomography of the whole body, digital subtraction angiography, arteriography, angiocardiography, venography, CT scan of the thorax. The drug is marketed under the name Xenetix.

Stannous pyrophosphate is a solid, fine crystalline product that is soluble in most acids. It has applications in the dental industry, especially inhibition of tooth plaque. It takes part in the stannous-pyrophosphate and technetium-stannouspyrophosphate complexes formation. This is diagnostic imaging agent for in-vivo labelling of red blood cells (RBCs) with 99mTc and areas of altered osteogenesis. It is a skeletal imaging agent used to demonstrate areas of altered osteogenesis, and a cardiac imaging agent used as an adjunct in the diagnosis of acute myocardial infarction.

Arclofenin was appointed as a suitable agent for hepatobiliary function studies

Iocarmic acid is a molecule used in seventies as a contrast media for myelography. Iocarmate meglumine (Dimer-X), a water-soluble salt of iocarmic acid was reported to be safe and best tolerated by central nervous system compared to metrizamide in a double-blind test in patients with symptoms of lumbar and sacral root involvement. In the experimental and clinical studies of Dimer-X used for ventriculography the apparent superiority of Dimer-X over Conray 60 and Angiografin as far as side effects were concerned was demonstrated, but there were no particular differences in the intensities of the ventriculograms obtained. Morphological studies of the ventricles and histological examinations of the ventricular walls 1 month after injections of Dimer-X into the ventricles of dogs showed no abnormalities. In the clinical studies, ventriculography Dimer-X, performed on patients with diseases of the central nervous system, produced ventriculograms of good diagnostic value with no side effects, such as convulsions, apart from mild headache or vomiting in 4 instances. Ventriculography with Dimer-X was carried in 15 infants with myelomeningocele and progressive hydrocephalus. However, as was shown in a number of studies iocarmate produced moderate to severe arachnoiditis from myelography in primates. Early meningitis side effects following lumbar radiculography with iocarmate meglumine were demonstrated.

Human secretin is a gastrointestinal peptide hormone that regulates secretions in the stomach, pancreas, and liver. Synthetic human secretin displays equivalent biological activity and properties as naturally occurring secretin. Acetate salt of synthetic secretin was marketed under the name ChiRhoStim. ChiRhoStim is indicated for the stimulation of pancreatic secretions, including bicarbonate, to aid in the diagnosis of pancreatic exocrine dysfunction, for the gastrin secretion to aid in the diagnosis of gastrinoma. ChiRhoStim is also used for the pancreatic secretions to facilitate the identification of the ampulla of Vater and accessory papilla during endoscopic, retrograde cholangiopancreatography (ERCP). When secretin binds to secretin receptors on pancreatic duct cells it opens cystic fibrosis transmembrane conductance regulator (CFTR) channels, leading to secretion of bicarbonate-rich-pancreatic fluid.

Cosyntropin (ACTH (1–24)) is a synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of adrenocorticotropic hormone. It is intended for use as a diagnostic agent in the screening of patients presumed to have adrenocortical insufficiency. Cosyntropin may bind to sites located on the adrenergic nerve endings associated with the cardiac tissue, and such binding would interfere with the neuronal reuptake of the catecholamines
