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 more
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
No: It's not necessary. The amount of radiation is small. ...Read more
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
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.
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
Had a CT scan of abdomen with iodine contrast and now doctors are saying I have Hashimotos disease. Could CT scan have caused this?
No: If there is a blockage of the kidney's urine drainage the the increased urine flow from the contrast injection can provoke grater distension of the renal collecting system which could well cause soreness. Let your doctor know about this to check for any compromise of your urinary drainage from a stone or ureteral stricture. ...Read more

I take 5 mg of methimazole daily for hyperthyroidism. What do I do before or after a CT scan with iodine contrast?
Iodine hyperthyroid: The iodine load of a CT scan can sometimes stimulate the thyroid to make more T4 and T3 (liothyronine) and worsen hyperthyroidism. But it probably will not, especially if your hyperthyroidism is controlled and you are taking your methimazole. Talk to your doctor. You may want to get your thyroid blood level checked about 2-4 weeks after the CT scan. ...Read more
What to do if I have allergy to iodine (lugols/surg prep.) gastrografin needed for CT scan. Is it safe for me to take?
Allergy: It probably wouldn't be cross reactive with gastrograffin because the allergy is not really to the iodine atom. However, if there is concern, there are alternatives to gastrograffin. For example, a diluted barium preparation, which contains no iodine, is perfectly appropriate as a CT oral contrast agent under most circumstances ...Read more
Am I able to take a Multi-vitamin that contains Iodine when I am allergic to shrimp? I had to be on an antihistamine while prepping for a CT scan.
The shellfish: Allergy leading to an increased risk of iodinated contrast allergic reaction is a myth that, unfortunately, is difficult to eradicate. There is nothing special about a shellfish allergy, if you have multiple allergies you are at some increased risk of a contrast reaction whether or not one of the allergies is shellfish. Also, no one can be allergic to molecular iodine. You can take the vitamin. ...Read more

Talk to your: Doctor about your concerns and allergy history. If you have a history of multiple allergies, you may be a candidate for pretreatment to minimize the chances of a reaction.

Barium: Barium leaves the body through the intestine in the feces. However, because barium is constipating, some patients may have trouble getting the barium out of the intestine. I would drink plenty of fluids, but if there is no bowel movement for 2 or 3 days, a laxative may be necessary so that the barium can be eliminated from the intestine. ...Read more
How long does radiation stay in the body? I had a cat scan at 36 (8 msv) am curious how that affects my cumulative radiation if my cells healed?
We are exposed: To radiation every day of our lives. A single CT scan is equivalent to approximately a year of environmental radiation exposure. Low level radiation does NOT always cause DNA damage, but it CAN cause DNA damage, which is why we try to limit the amount of CTs we get. A single CT barely raises your lifetime cancer risk above baseline, but ask your doctors to limit your exposure as much as possible. ...Read more
