Study Notes
Contrast Agents
- Contrast agents are the most widely used agents in medicine.
- These agents are characterized by their ability to pass freely through arteries.
- However, they are poorly distributed within veins and their concentration is significantly reduced as it passes into the venules.
- The contrast agent concentration is significantly reduced in the capillary bed.
- The difference between the concentration in the aorta and inferior vena cava will be less than 10.
Timing for Contrast Agents
- The equilibrium stage is the worst stage for obtaining bodily scans, and especially the liver.
- After a contrast agent injection, the contrast agent needs time to cross over the blood-brain barrier.
Contrast Agent Delivery
- Drip methods are used to allow contrast agents to respond quickly.
Adverse Effects of Contrast Agents
- Adverse effects of contrast agents can be categorised as either allergic or idiosyncratic reactions.
