After CT scan what is duration of contrast medium (iodine) in body?

Are you sure.: If radio active iodine is used it is i-131 which has half life of less than 9days, then calculate every 9 days half of it will be eliminated in the body with i -131. Not bad if we did not synthesize i- 131 imagine if it is i- 129 which had half life of 15.7 million years. ...Read more

I'll need radioactive iodine therapy in 2 weeks for my thyroid cancer.How can I get rid faster of the iodine in my body from a CT scan i had yesterday?

Not likely to work: If you received IV contrast with the ct scan, you will not be able to receive radioactive iodine in 2 weeks. It can take months for the iodine from the contrast to be excreted. You may be able to increase the rate slightly by taking a diuretic, but the best thing will be to wait at least 2 months. ...Read more

Can iodine contrast used for CT scan inadvertently improve symptoms or issues?

Can iodine contrast used for CT scan inadvertently improve symptoms or issues?

Probably not: I like to keep an open mind but there is no scientific evidence that contrast used for CT can be used to treat disease. If you are feeling better after a CT exam, it is likely that you were on your way to getting better before the scan and the improvement continued after the scan to a point that you then noticed it. ...Read more

If I am allergic to topical iodine, can I have intrevenous iodine for a CT scan with no reaction?

Maybe: Ct contrast agents is usually iodinated and are classifed as either ionic or non-ionic. Some are more allergy-prone than others. Ct scan contrast is totally different than MRI contrast. In contrast, MRI contrast agents usually contains chelated gadolinium. Tell the radiologist about your previous ct scan contract allergic symptoms when getting your mri. ...Read more

Brain Aneurysm: I assume you mean brain aneurysm, in which case the answer is no. A 2cm aneurysm is very large and will be easily detected by contrasted ( or non/contrast) ct scan. If by chance you are mistaken and mean 2millimeter, not centimeter, it is very easy for a ct to miss. ...Read more
