Do they usually use dye surrounded by cranium CTs?
I had one last night and they didn't use dye. Just wondering if that's adjectives practice and why they use dye, versus why they do not (as far as head CTs are concerned).
Answers:
If it's in the setting of a headache or a head injury they would first do it minus contrast (dye). The reason for this is because if there's a bleed, it will look the same as contrast so it's critical not to confuse the two.
Contrast is used contained by CT when they are looking for some sort of inflammatory process, typically. Such would be, say, a tumor in the brain or an infectious process where you'd see the contrast congregate where these processes occurred.
When a patient is brought within through the ER (ED), it's extremely rare that the ER physician would order a contrast enhanced CT (with dye). It's almost exclusively used to look for acute injury and dye would only form that more difficult to see.
Have a good day.
