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

Very unlikely: If you are asking about the risk after a single head ct scan it is not measureable and is not considered a risk for developing a brain tumor. If for some reason you have many routine head ct scans especially if done throughout childhood there is a very small slight increase risk of developing a tumor but far less than .5%. The low dose of radiation from modern ct scans is negligible if used safe. ...Read more

Computed Tomography (Definition)

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

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 so worry?

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 so worry?

And why the Head CT: 3 years ago? The chance of a head ct causing a brain tumor is extraordinarily low for an individual probably less than 1/10, 000 studies. See a neurologist or get an excellent history and exam before any further studies. ...Read more

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

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

Radiation dose chart: We only want to take the minimum number and type of x-rays or scans in order to properly diagnose and treatment plan. Without that we might either miss something or the final result might be compromised. Here is a good website for you to look at: http://www.Ans.Org/pi/resources/dosechart/. ...Read more

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?

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?

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 ...Read more

Is getting a second CT scan within a year too much radiation?

Is getting a second CT scan within a year too much radiation?

Too much?: "too much" is a relative term. Basically no. If you have a medical condition, ie cancer that is being monitored by ct then the benefits outweigh the risks. If you are getting a ct for no reason then the risks (small but finite) outweigh the benefits. Any medical procedure is not a binary state. There is a continuum of risks and benefits. ...Read more

Does the CT scan shows the radiation dose used in the scan in mSv?

Does the CT scan shows the radiation dose used in the scan in mSv?

10 mSv: A CT scan of the abdomen (belly) and pelvis exposes a person to about 10 mSv; this goes up to 20 mSv if the test is done twice (once with and once without contrast). ...Read more

How long is it supposed to it take for the radiation from CT scan to have harmful effect?

It depends, if ever.: The tissue damage done by radiation exposure is related to the dose, the age of the patient and the organs that receive the dose, as well as genetic factors relating to the patient. Also, the time between exposures is important. Almost any single ct exam of any one body part is exceptionally unlikely to cause any harm. The issue is repeated imaging of the same area, particularly in young patients. ...Read more
