This site has questions answered by qualified medical personel regarding such issues. You can search the site for answers which are more specific....for example, what type of CT scan.
Here is an example:
"Q: Your site offers great information. I see a lot of questions about abdominal CTs, etc. However, nothing is mentioned about the urinary tract per se. I am scheduled for a spiral CT scan of the kidneys and bladder. Is there a higher radiation dosage for a spiral versus regular CT? Will this affect fertility in the future?
A: The important question is: Is this CT scan really necessary? Has it been ordered by your physician? Or is it a screening procedure you have scheduled yourself? The reason for this is that all authorities recommend that for medically justified exposures, such as CT, the potential benefit outweighs any potential risk. If the procedure is a self-referred screening exam, that may not be the case.
As to your question about dose, the spiral scan frequently involves a larger dose than conventional technique. Patient dose depends on the details of how the scan is conducted. The spiral procedure may or may not involve a higher dose than a conventional scan. Measurable effects on fertility require a much larger dose than either CT technique delivers. The only potential risk to future offspring from radiation is a genetic effect, that is, an abnormality that is conveyed to future generations. These effects are well known in experimental animals (fruit flies, rodents, etc.) No such effects have ever been demonstrated in humans.
Conclusion: If your CT scan is medically justified, then radiation dose is not a major concern.

After 5 lumbar fusions, I've had my fair share of not only ct scans but mri's & x-rays too! I'm ok so I'd have to say yes they are safe.

I have had several over the last 10 years with no apparent ill effects. At the latest one I was injected with a dye which caused an immediate warming sensation which is normal.

they are a form of radiation, like an x-ray. over exposure to radiation is not good. i personally avoid as much radiation as possible.

I think it's safe, but they're very scary! You'll feel like you're in a casket or something. Very creepy... hope you don't need one!
