Understand the Problem
The questions are related to various medical and scientific concepts, including service coils, blood-brain barriers, surface tension, iodine contrast media, and MRI. They seek explanations and definitions of these topics.
Answer
1. Service coil: tubing for heat transfer. 2. BBB: protects brain, Iodine contrast disrupts it. 3. Surface tension affects media spread. 4. Iodine contrast types: ionic/non-ionic. 5. Not used in MRI due to different imaging method.
-
A service coil is typically a coil of tubing used in heating or cooling systems to transfer heat.
-
The blood-brain barrier (BBB) is a selective permeability barrier that protects the brain from harmful substances. Iodine contrast can disrupt the BBB due to its hypertonicity, making it crucial to use low or iso-osmolar agents.
-
Surface tension is the cohesive force at the surface of a liquid. In iodine contrast, surface tension can affect how the contrast media spread and coat tissues.
-
Types of iodine contrast media include ionic and non-ionic, divided into monomers and dimers, with non-ionic being more prevalent due to fewer side effects.
-
Iodine contrast is not used in MRI because MRI relies on magnetic fields and radio waves instead of X-rays, and gadolinium-based contrast agents are preferred.

More Information
Surface tension and the blood-brain barrier play crucial roles in how contrast media interact with the body. Modern contrasts are designed to be safer and more effective.
Tips
Confusing different contrast agents with each other can lead to misunderstanding their specific applications.
