How many CT scans are safe in q year?

How many CT scans are safe in q year?

None or a lot: The question is less about how many are safe and more about the question you're trying to answer. If you've been in a major car accident and are bleeding to death, 10 cts are very safe. If you are just curious to see your insides, none are safe. It is a decision of the risk of the scan versus the benefit of the information gained. It should be discussed with your md ordering the exam. ...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

Had several x rays and CT scans this year . Maybe 7 cts and 14 x rays . Is this deadly?

Not deadly: It's not deadly but you should make your doctors aware of all the radiation you've recieved. The bigger question is why so many cts? Are they all really necessary? ...Read more

I've had about 8 CT scans this year can it kill me ?Im scared.Lot of problems .Can i die from that many? What symptoms to look for?

Understand concern: The question is why he had had 8 ct scans in 1 year. You will not die from that many, but you are receiving a small dose of radiation with each one.Your cumulative risk of getting cancer increases over your lifetime if you continue to get scans at this rate. Please stick with one doctor and let him/her manage your care and figure out what is going on with you. ...Read more

I might need two CT scans this year one for abdomen and one for chest, is that to many, could that many be risk to my health?

Very small risk: If appropriately used, the medical benefit of ct scans far outweighs the potential risks associated with radiation from ct scans. We are all exposed to natural background radiation in normal daily life, and the radiation from a ct scan is not much more than the radiation an average person gets exposed to in a year. ...Read more

I'm 17 I've had 2 CT scans of the head in one year I'm so scared that I'm going to get cancer! I need some reassurance I'm freaking out !

You will be ok: Radiation exposure is a necessary consequence of CT scanning. However, the amount of exposure from one head CT is equal to about half of the annunal exposure to radiation that someone gets who lives in Denver. In the amount that you are talking about some experts think that radiation from 10-15 head CTs might offer a 'slight' increase in cancer. ...Read more

Is it bad too have too many x rays taken? I've had some major injuries in the past year and i've had over 20 sets of x rays, and a couple CT scans

It's best to...: Avoid unnecessarry radiation if at all possible. Having said that, your doctors must have been concerned enough about injuries to get the exams so the benefits likely outweigh the risks. Plain xrays (radiographs) give very little radiation dose. Ct scan dose is relatively much more but still a typical ct of the abdomen and pelvis may be equivalent to about 1-2 years of background radiation. ...Read more

I've gotten a few scans this year. 3 CT scans and 3 mri, one with contrast. Can I have cancer because of it?

I've gotten a few scans this year. 3 CT scans and 3 mri, one with contrast. Can I have cancer because of it?

Extremely unlikely: So unlikely that the likelihood approaches zero. You have more radiation exposure on a cross country flight, or hiking at altitude. That said, WHY did you have all those scans? If you have had unintentional weight loss, night sweats, or other unexplained pain, the scans may be looking for cancer. But the risk of cancer due to the scans is nearly zero. Why did you have them? ...Read more
