Study Notes
Contrast Media
- Contrast media are diagnostic radio-opaque substances of high density used to improve image resolution.
- Contrast media types vary depending on administration route and anatomical structure being examined.
Types of Contrast Media
- Oral route: Barium Sulfate and Gastrografin.
- Intravenous (IV) route: Iodinated, with high or low osmolarity.
- MRI agents: Contain Gadolinium and Iron.
- Ultrasound agents: Contain albumin.
Osmolarity
- Low osmolar contrast media are 5-10 times safer than high osmolar contrast media (HOCM).
Contraindications
- History of previous reactions to contrast media.
- Renal failure
- Uncontrolled asthma
