Question 1

if my head ct scan radiation gonna cause a brain cancer to me i  need to start worry about it after 5 years or 20 years and more after the scan?scared

Accepted Answer

Don't worry: Though there is a very small increased risk of certain cancers associated with radiation, the risk is much higher in young children who have multiple ct scans.  Brain tumors are rare and the absolute risk for an adult who has had one or a few head cts is only very slightly higher than those who do not have head ct scans.  The risk is still very low and should not cause you any anxiety or fear.

Question 2

i had one head ct scan and two brain spect scan in three years. all normal. how many brain cells would have died because of the radiation i received?

Accepted Answer

None: RELAX. You forgot to mention the reason for these studies. Presumably there was a benefit.

Question 3

do you thing the radiation i got from head ct scan 3 years ago gave me a brain tumor-im asking because im having a brain tumor symptoms now im worry?

Accepted Answer

Probably not: The dose from a single ct scan probably would not cause you to develop a brain tumors.  Most brain tumor are sporadic.  It pretty much impossible to predict who will develop one and why.  Please see your doctor if you are worried.

Question 4

can a head  ct scan (with and without contrast) radiation cause a brain tumor to grow and cause symptoms in 2 years and 8 months or 3 years? possible?

Accepted Answer

Unknowable: Unfortunately, no one can definitively answer your question. Your question can be answered statistically (radiation from radiology procedures does cause a certain number of cancers if you study large numbers of people), but we can never say for sure exactly which cancer cases were caused by such radiation.

Question 5

should i do & how much radiation ct scans for one dental implant causes vs regular chest/head ct scan or one digital tooth x ray. i am curious to know

Accepted Answer

Should you do ?: Answer is yes, if your surgeon is requesting digital images of your surgery site. The amount of radiation is least for a single dental film, and obviously more for a scan that has to pass through more tissue. What you must remember is that the dosage is of diagnostic strength, not occupational exposure. Millions of images have been taken without a problem.

Question 6

i did head ct scan 10 years ago and thoracic spine mri 1.5 years ago
and a chest x-ray 6 months ago
i'm worry about the amount of radiations?

Accepted Answer

Minimal: MRI does not use x-ray radiation, but instead uses a magnetic field.  A single chest x-ray is very minimal.  A CT scan of the head will give you about 20 times as much radiation as a chest x-ray, but this is still felt to be less than the background radiation you receive in 1 year just from being outdoors.  It's good for you to limit your radiation exposure,but yours is minimal, I wouldn't worry

Question 7

for my new job admission i was asked to undergo for hep a-b-c and hiv testing this week as well as for some vaccine titers, but i just had 2 side lumbar xrays and a head ct scan last week, can that radiation affect the test results?

Accepted Answer

No: radiation has no effect on the blood tests noted, wish you well

Question 8

how dangerous is head ct scan?

Accepted Answer

Go to: Acr accredited scanner to be safest. Only small risk. See radiologyinfo.Org.

Question 9

can a non contrast head ct scan miss anything?

Accepted Answer

Yes: A ct scan with IV contrast will be more sensitive for detecting lesions than a non-contrast ct, and an MRI with contrast is even better than a ct scan.

Question 10

what does a head ct scan rule out, if you fell and hit your head?

Accepted Answer

Hematoma: The main "rule out" would be a hematoma (blood clot) between your brain and skull, which could expand and cause neurological problems.  There is little extra space in our skulls, so it's important not to have anything more in there than brains.  Our brains are quite soft, and can be injured or bruised when we fall and hit our heads.  There could also be active bleeding, which a ct scan could show.
