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
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
When would CT scan cancer effects show up? If i received too much radiation as a result of CT scans, when would the cancer potentially show up? Could i get canncer in 10-20 years because of CT scan radiation?
Delayed, high dose: In general, ct scans do not by themselves cause cancer. You would have to have had dozens upon dozens to risk the development of cancer. Having said that, when radiation induced cancers development, they are usually in the field of radiation, and usually are sarcomas (soft tissue malignancies). Based on your age, you would have to have had hundreds of cts in a short time 15-20 years ago. ...Read moreSee 1 more doctor answer
Can you get to much radiation from CT scan? Can it kill you years later from cancer? How bad is to get CT scan at the age of 30yr. I had one chest ct.
Don't worry: The radiation exposure from a single chest ct is ver low and provides either very little or no additional risk. ...Read more
How long does it takes to get radiation induced cancer? Should i worry after 5 to 10 years as i had on chest CT scan month ago with 4.8msv dose?
May not even happen: The average ct scan in the us exposes us anywhere between 3 and 10 msv. A dose of 10 msv increases the risk of getting any cancer by 0.1% and the risk of fatal cancer by 0.05%. According to the national research council and the U.S. Fda, any person has a 20% risk of dying from cancer in their lifetime. One ct scan of 10msv would increase the chance to 20.05%. Not a big risk. Don't worry too much. ...Read moreSee 1 more doctor answer
I'm a 30 year old male. I had one CT scan done without contrast and now have to do one with contrast, is this a dangerous amount of radiation?
Benefit ;: Risk depend on indication for studies. We tend to select who to do both. Many scans are now low dose. It's best to have a family doctor that knows you and decides when to do ct's rather than er which does more. The risk is population based, trivial increase for individual (1 in 10 thousand to 2/10k). ...Read more
Had a bone scan and a CT scan today. Can i still care for my 6 month and 3 year old? Any radiation worry?
I've had a neck ct scan and four x-rays and a hida scan? I'm worried about the radiation exposure... Should I? All in the past year, I'm a 34yr F.
CT scan; not the Xra: CT scans involve ~400 times more radiation exposure as Xrays, & so if u worry abt unnecessary radiation risk, limit CT scans. HIDA & Xrays involve so little radiation that u prob got as much from walking outside in 1 yr as u got from those tests. At 34, most of ur organs have developed, so there's no immediate threat; however, there's a lifetime radiation limit. Too much testng will catch up 2u@80 ...Read more
Lost 10lbs past year. Now 5'11", 165lbs. Blood test normal. Doc. Ordered ct-scan abs, pelvis, chest. Saw "temporal wasting." concerned about radiation?
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
