Study Notes
Contrast Media
- Iodine has an atomic number of 53.
- Barium sulfate is used to coat the lining of organs and is supplied in different thicknesses.
- Water-soluble iodine contrast media is safe to use if perforation is suspected but very harmful to lung tissue.
- Gadolinium is used as a contrast agent for MRI.
- If gadolinium is not excreted from the body, nephrogenic systemic fibrosis (NSF) can occur.
- The purpose of using contrast in a CT scan is to enhance the visibility of internal structures.
- A side effect of CT scan contrast can be an allergic reaction.
- Chelating agents are used to bind to gadolinium and facilitate its excretion from the body.
- Radiographic contrast media is characterized by its high atomic number and opacity.
- The main factor that influences radiographic contrast is the density of the material.
- Invasive procedures include angiography, arthrography, and myelography.
- Radiographic contrast media is excreted from the body through the kidneys.
- The approximate half-life of radiographic contrast media is 1-2 hours.
- The urinary system is most commonly affected by physiologic changes produced by contrast media.
- The main application of ultrasound contrast agents is to enhance the visibility of blood vessels and tissues.
- Iodine as a contrast agent is not MRI-compatible.
- Ionic contrast media is high-osmolality and causes more discomfort and side effects.
- Oil-based iodine contrast media is viscous and causes more side effects.
- Factors that contribute to discomfort, side effects, and reactions during contrast media administration include osmolarity, ionic properties, and injection rate.
- Renal failure is a contraindication for iodine contrast media.
