Welcome. My name is Devine. This is episode 478 of the Devine Intervention Podcast. And to these

podcasts I'm going to be discussing a topic that medical students have for the longest time struggled with.

Really it's my hope that after you learn this topic, it will give you a very nice useful

framework for approaching a very common problem.

So into this podcast I'm basically going to and it's going to be a short

podcast I'm pretty much going to be discussing when you should use CT with contrast and when you should not use CT with

contrast right so when should you order CT with contrast and when should you

get CT without contrast.

Okay, that's the big focus and then at the end of the discussion today

we will go ahead and talk about a quick life lesson.

There's a quick life lesson I have that we're going to discuss.

So again, this is going to be more conversational, but I think the very first thing you need to keep in mind is, you know, C.T, what's the contrast we use for C. T? Obviously the contrast for use for C.T. is iodine, right? They are iodine based for the most part.

Most of the contracts we use for CT,

for the use-mail exams is iodine-based.

And again, as I go and I'll try to make some integrations,

I'm pulling some classic scenarios and things you may see on your on your

exams. So obviously right like there's a few problems with contrast that you want to be aware of

right so like for example they can give you a question about a person that you know gets contrast for an imaging study then all of a

sudden the person begins to have like shortness or breath, begins to have

fevers, begins to have lip edema. Obviously this person has an allergic contrast reaction.

And you know one easy thing they can easily test here is, oh, what's the biggest risk factor for an allergic contrast reaction? Well, it's going to be a prior history of an allergic contrast reaction. If you've had a contrast reaction before,

chances are pretty good that you may have it again.
