Your CT scan will use contrast, a special dye given through an IV. The contrast helps certain organs, blood vessels, and tissues show up more clearly on the images.
When the contrast goes in, you may feel warm or flushed for a short time. You may also notice a metallic taste. These feelings usually pass quickly.
Before your exam, tell the imaging team if you have ever had a reaction to contrast. Also tell them if you have any kidney problems.
Contrast is generally well tolerated, but it is not risk-free. If you have trouble breathing or your throat feels swollen after the injection, tell staff right away. These symptoms need immediate attention.
Your preparation instructions depend on your exam and your own situation. The imaging team will give you the instructions that apply to you. If you are unsure about anything, ask them.

Your CT scan will use a special liquid called IV iodinated contrast. This contrast is given through a vein. It helps certain organs, blood vessels, and tissues show up more clearly on your CT images.
During the injection, you may feel a brief warmth or flushing sensation. You might also notice a metallic taste in your mouth. These feelings are common and usually go away quickly.
Before your scan, tell the imaging team if you have ever had a reaction to contrast or if you have any kidney problems.
If you experience trouble breathing or swelling in your throat after receiving contrast, tell the staff immediately. These symptoms need prompt attention.
Your preparation instructions may differ depending on your exam and medical needs. If you have questions about what to do before or after your scan, ask your imaging team.

03 / The accepted findings
Where the wording
left the source.
The supplied facts did not establish general tolerability or how common the sensations are. Robert accepted both source-adherence findings. Neither finding claims the added wording is medically false.
A-01 / Claude response
Finding acceptedReassurance beyond the packet.
Exact response excerpt
“Contrast is generally well tolerated, but it is not risk-free.”
The five facts do not describe general tolerability. This reassurance introduces a medical claim outside the permitted reference material.
Suggested correction
Remove the added reassurance sentence. Retain the instructions to report breathing difficulty or throat swelling immediately.
B-01 / ChatGPT response
Finding acceptedFrequency added to a possibility.
Exact response excerpt
“These feelings are common and usually go away quickly.”
Fact 2 says these sensations can occur and usually pass quickly. It does not establish how often they occur.
Proposed replacement
“These feelings usually go away quickly.”
Acceptance applies to these two findings. No overall clinical-suitability rating, model ranking, or approval of the complete responses is recorded.
