Contrast Dye

Homework?

What have you found out already?

Do your own homework.

Boy, some great advice given by the previous posters

While I do agree do some research on your own. Your question is a good question but the answer is very broad.

First, are you talking about Oral or IV contrast dye?

Second, are you referring to CT scans only or also XR, fluoroscopy, and MRI?

In general when given through the IV it gives the radiologists a better view of everything. It highlights solid organs, it defines blood vessels, and overall gives more detail than a CT without contrast.

With oral contrast, you can see more detail of the hollow organs (stomach, intestines, etc).

You asked a very broad question and my answer only scratches the surface. I would do more research to fully understand not only oral and IV contrast but also the different kinds of contrast we use, and the things we are trying to diagnose.

Do your own homework.

What a troll

As a radiology nurse, I agree that this is a very broad question. Radiographic contrast media (it's not actually a dye”) comes in many forms and brands for a wide range of imaging procedures. We even give contrast for certain ultrasound studies now. Depending on the agent being administered, the potential side effects, contraindications, and potential for adverse reaction will vary.

What a troll

Haha! I seem to have made quite the impression.
