What is non ionic contrast media?

What are Non-ionic iodinated contrast media? Iodinated contrast media is a contrast media containing iodine that is used in radiography to increase the clarity of the image. Iodinated contrast media can be divided into the two groups: ionic and non-ionic. Each group varies in their uses, properties and toxic effects.

What is high osmolar contrast used for?

High osmolality contrast media HOCM remain used for gastrointestinal and cystourethral administration, including the following agents: diatrizoate sodium/meglumine (Gastrografin, MD-Gastroview, Cystografin)

What is low osmolar contrast used for?

During the past decade low osmolar contrast media (LOCM) have become increasingly popular for radio- graphic procedures requiring intravascular contrast because they have been found to cause less discomfort and fewer cardiovascular and anaphylactoid adverse effects than high osmolar contrast media (HOCM) [2].

Why is iodine used in contrast?

Iodine has a particular advantage as a contrast agent because the k-shell binding energy (k-edge) is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography 1. When the incident x-ray energy is closer to the k-edge of the atom it encounters, photoelectric absorption is more likely to occur.

What are the side effects of iodine contrast dye?

Iodine-based Contrast Materials

  • nausea and vomiting.
  • headache.
  • itching.
  • flushing.
  • mild skin rash or hives.

What are nonionic surfactants used for?

Non-ionic surfactants are used as a grease remover in detergents, household cleaners and dish soap. They offer excellent solubility and produce a low amount of foam. When combined with anionic surfactants, non-ionic surfactants provide resistance to hard water in textile detergents.

What is a nonionic compound?

A nonionic compound is a substance composed of atoms held together by chemical bonding forces, called covalent bonds. Covalent bonds are formed by sharing a pair of electrons between two atoms, and will be covered in more detail later.

What dye is used for CT scan?

Iodine-based and barium-sulfate compounds are used in x-ray and computed tomography (CT) imaging exams.

What is iso osmolar?

isoosmolar (not comparable) Having the same osmolarity.
