What to do if I have to have a CT scan how safe is the contrast dye?

FDA review demonstrated a rate of 2.1 fatalities per 1 million injections. ...Read more

Can a CT scan without contrast dye rule out causes of a secondary cough headache?

CT without contrast: Will show whether there is hydrocephalus ("water on the brain"), fluid collections around the brain, and large mass lesions (tumors).

Increased urine output? I did have a CT scan of my chest yesterday, I heard that the dye can cause increase urine the day after.  Is this true?

We'll sort of: the older X-ray dyes or contrast media were hypertonic and did cause a dieresis. Urine output would go up. The newer nonionic media might cause a slight increase. It is still advised to drink water afterward to flush those hardworking kidneys ...Read more

Good morning.  I recently had a CT scan performed. As part of the preliminary test, they did a creatinine screen.  My level was 1.24 and egfr of > 60.

Good for you: I am a pathologist and lab specialist. Serum creatinine has a lot to do with muscle mass. When I was lifting weights every day, mine ran 1.6 to 1.8. The GFR's estimated from spot creatinines are subscience and even include a racial adjustment "because black people are more muscular." It is bogus. Be grateful for good health. ...Read more

Most radiology facilities screen patients prior to the exam to insure the safety of using the contrast media. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
