Ct Scan Head Radiation
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 moreSee 2 more doctor answers
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
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?
None: RELAX. You forgot to mention the reason for these studies. Presumably there was a benefit. ...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 im 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?
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?
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 moreSee 2 more doctor answers
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
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?
No: radiation has no effect on the blood tests noted, wish you well ...Read more
Mini sinus Ct scan 3/17 tooth mini Ct scan 1 side 6/17 & again one week later is it too much radiation if I now have a regular Ct scan of face/neck ?
Is head MRI is safer than CT scan ? My doctor told me to a CT scan but concerned about irradiation ? So do they have the same indications ?
MRI: Is generally a better test. Depends on the indication. Ct does have radiation but is a small amount. ...Read more
While: You are in the scanner and the images are being taken you are receiving a relatively small dose of radiation. Often this is less than a minute depending on what is being scanned. ...Read more
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
Low: The technicians know how to properly control the radiation levels that you would be receiving. ...Read more
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
I had 2 CT scans within a month after two hard hits to the head. Is this dangerous in terms of radiation? Never had one before.
Radiation exposure: Yes, you were exposed to radiation, but I am sure that your doc considered the tests necessary and the overall exposure is low. ...Read more
