Iobenzamic Acid

	Iobenzamic Acid Iobenzamic acid is a pharmaceutical drug used as an X-ray contrast agent. It is a water-soluble, hepatotropic contrast medium, meaning it is taken up by the liver and gallbladder. This makes it useful for imaging these organs. See also * Iodinated contrast Iodinated contrast is a form of water-soluble, intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiography, radiographic procedures.

picture info	X-ray Contrast Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iodine, or more rarely barium sulfate. The contrast agents absorb external X-rays, resulting in decreased exposure on the X-ray detector. This is different from radiopharmaceuticals used in nuclear medicine which emit radiation. Magnetic resonance imaging (MRI) functions through different principles and thus MRI contrast agents have a different mode of action. These compounds work by altering the magnetic properties of nearby hydrogen nuclei. Types and uses Radiocontrast agents used in X-ray examinations can be grouped in positive (iodinated agents, barium sulfate), and negative agents (air, carbon dioxide, methylcellulose). Iodine (circulatory system) Iodinated contrast contains iodine. It is the main type of radiocontrast used for intra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Iodinated Contrast Iodinated contrast is a form of water-soluble, intravenous radiocontrast agent containing iodine, which enhances the visibility of vascular structures and organs during radiography, radiographic procedures. Some pathologies, such as cancer, have particularly improved visibility with iodinated contrast. The radiodensity of iodinated contrast is 25–30 Hounsfield units (HU) per milligram of iodine per milliliter at a tube voltage of 100–120 kVp. Types Iodine-based contrast media are usually classified as ionic or nonionic. Both types are used most commonly in radiology due to their relatively harmless interaction with the body and their solubility. Contrast media are primarily used to visualize vessels and changes in tissues on radiography and CT Scan, CT (computerized tomography). Contrast media can also be used for tests of the urinary tract, uterus and fallopian tubes. It may cause the patient to feel as if they have had urinary incontinence. It also puts a metallic taste in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Iodobenzene Derivatives Iodobenzene is an aryl iodide and the simplest of the iodobenzenes, consisting of a benzene ring substituted with one iodine atom. Its chemical formula is . It is useful as a synthetic intermediate in organic chemistry. It is a volatile colorless liquid, although aged samples appear yellowish. Preparation Iodobenzene is commercially available, or it can be prepared in the laboratory from aniline via the diazotization reaction. In the first step, the amine functional group is Diazonium compound, diazotized with hydrochloric acid and sodium nitrite. Potassium iodide is added to the resultant phenyldiazonium chloride, causing nitrogen gas to evolve. The product is separated by steam distillation. : Alternatively, it can be produced by refluxing iodine and nitric acid with benzene. Reactions Since the C–I bond is weaker than C–Br or C–Cl, iodobenzene is more reactive than bromobenzene or chlorobenzene. Iodobenzene reacts readily with magnesium to form the Grignard reagent, ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
