Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

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 moreSee 1 more doctor answer
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

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 moreSee 1 more doctor answer
Not aware of testing: The risk of an adverse reaction to non ionic IV contrast dye is very low, less than 1 in 100 injections. Most of the reactions are mild and easily treated. Severe reactions occur in 1-2 per 10, 000 injections of IV non ionic contrast. If a person was severely allergic to many different things, perhaps a consultation with an allergist could be obtained. ...Read more
Hi, can iodine CT scan miss 2 CM aneurysm ? I guess it can seem a weird question with a obvious no but i d like to be sure. Thanking you in advance.
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 moreSee 1 more doctor answer
Did my CT scan said to drink 6-8 glasses of water for the next 3 days to clear my system from iodine, what happens if i don't? Not a water person..
Yes, but...: Reactions to contrast are usually not caused by a true allergy to iodine (which is rare). Low-ionic strength contrast should be used if you have a history of reactions to contrast, and the radiologist will give you antihistamines and corticosteroids (prednisone) before the test to help prevent a reaction. With this regimen, scans are usually very safe. Talk with the radiologist about your concerns. ...Read more
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
