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
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 4 CT scans done on my head this year due to feeling weird and lost and head aches . Would it be safe to get a MRI ? I know 4 CT scans is a lot.
I've had about 8 CT scans in the past 2 years. Neurologist wants to do a mri. How safe is a mri? Worried of radiation .
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
Had two CT scans on head this year and one on lower body is that dangerous how do I know if it will harm me ?
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?
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
I've had to many CT scans this year maybe 8 on diff parts of body.Does a MRI have same amount of radiation ?
Is there any system for tracking how many CT scans you can have every year since I am moving across the country?
Number: There is no limit on the number of ct scans you can have. If you need the imaging studies they should be performed. However, all physicians should try to limit the number of exams you need and repeat only as necessary. There is radiation exposure with a ct scan and you always want to limit this as much as possible. No need to repeat if all you need is a copy of the exam. ...Read more
Since january of this year I have had a colonoscopy upper endoscopy abd us's several abd/pel CT scans hida scan n negative, why do I still have pain?
Ask your doc!: Most appropriate for the doctors that have ordered all these tests to discuss the results with you, and give you a clue as to what they have found or not found (sometimes even more important!). Any other answer is a guess on anyone's part--if all the tests really are 'normal' you should be reassured that nothing horrible hads been found thus far! ...Read more
I have had 3 CT scans this last year and a couple chest x rays and back xrays. Does that increase chances of cancer? What should I do?
Wut is causing my body tremors? Normal MRI & CT scans. No answer for a year & a half now. Very frustrated. I don't drink or do any drugs.
Essential tremor :
Is a neurological disorder that causes a shaking. Essential tremor can affect almost any part of your body. The hands are the most affected, especially when performing simple tasks, such as drinking from a glass, writing or shaving. Good news is not a dangerous disorder, but can worsens over time and can occur at any age.
See a neurologist to rule out the parkinson's disease. ...Read more
29 year old female 2 head CT scans without contrast within 2 months of one another. What is my cancer risk? I have read "small" or "negligible"
Two CT scans will not raise your risk to a measurable level, above your background risk.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more
I had a thorough neurologist workup last year. CT scans, MRIs, EEG and they found nothing. Follow up Qeeg showed nothing. Once I have BM I feel ok.
Had CT scans done on head this year for migraines and confusion.Would it have shown increased icp? I have popping feeling and sound when turn head.
Sometimes: Ct and MRI scans can show some disorders that cause increased intracranial pressure (icp) such as a mass, but they cannot measure the pressure itself. There are also some conditions such as pseudotumor cerebri that are associated with increased icp, but the scans can appear normal. The only way to directly measure the icp is by a spinal tap or other similar test. ...Read more
I had two pelvic/abdomen CT scans in one year. Should I be concerned? It said two exposures per CT scan each at 15 msv.
The increased: risk is minimal. But you can calculate it with an interactive tool at xrayrisk.com ...Read more
Been having neck and head aches only when laying down at night.Motrin hardly helps.Had 3 CT scans done this year on head all came back good?
51yo had 2 CT scans + 3 MRIS during lifetime + 50+mammo pics last year due to complication of biopsy. Is it too much radiation to do kidney CTw/ctrst?
A balance is needed: The mri is not an issue. The number of mammograms seems to me to be excessive but that would depend on the complication. The CT of the kidneys should be no issue. One must balance the benefits vs the potential risks. You should also discuss your concerns with your doctors. Perhaps some of any further imaging be done with MRI ...Read more
Have received roughly 25msv of radiation from CT scans past three year. Will have no more unless absolutely nessecary! 22yr m vegetarian, eat lots of fruits and veg, what is the risk of cancer? Scared
Less dose than airli: This is a very low dose compared to other risks in our environments. It is less than an airline attendant who makes a couple of transcontinental trips a year. I think we would all be well advised to limit unnecessary radiation but if there is a medical need i would have no problem getting another ct or pet scan. The only exception would be a pregnant woman in first trimester. ...Read more
Do CT scans cause damage to ovaries? Three or four had been done this year. Will transvaginal sonogram show if damage is done?
No: No and no. Why are you having so many? Check with your gyno or get a second opinion. ...Read more
Pencil thin stools over a year some small amounts of blood. 3 CT scans this year all normal. No colonscopy, is it unlikely to be cancer given scans?
Let me advise you:
Pencil thin stools can be caused by a narrowing in the colon, rectum or anus, or may occur as a result of many things.
Pencil thin stools may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. Conditions that affect the digestive tract may also involve other body systems.
I strongly advise you to have coloscopy.
Good luck. ...Read more
I've had 6 CT scans in a year. Is this really dangerous for me? Should I be worried about getting cancer now? The CTa were: 1 head, 2 abdomen, 3 chest
Almost no risk of Ca:
Please see: http://www.scientificamerican.com/article/how-much-ct-scans-increase-risk-cancer/
1) Risk of induced Ca from 6 CTs is very, very low.
2) There may be cellular repair at doses as low as CT, limiting cancer induction. (We don't know how much).
3) Whatever the theoretical risk, there must be a good reason to do the CT in the first place. I would worry more about why so many CTs. ...Read more
What is the danger of having too many CT scans? I'm concerned about the radiation. I've had 3 CT scans within one year. I have heard that people have died of bone cancer caused by too many xrays. Is this the same?
Too small to measure: Pilots get an extra 3 mSV yearly and radiation workers up to an extra 20 mSV yearly. This is cumulative. A common CT scan delivers may be 3, a very sick person who needs chest and abdomen with and without contrasts gets 40. No one has been able to measure any increased cancer risk in pilots or radiation workers. I'd stop worrying. If you need the scan, don't hesitate. ...Read more
Child had 2 separate head CT scans as an infant, now healthy 6 year old. How concerned should we be about increased risk of cancer as a child?
Stop worrying...: ... And be effective. The slight increase is real but there is not a thing to do about it, and ct's that get ordered appropriately in children are worth the tiny risk. Plan for your child to have a normal life, teach him/her the social and job skills that tomorrow's competitive world will require, and create a winner rather than a worrier. ...Read more
Child had 2 head CT scans as an infant, now is a healthy 6 year old. Should we be concerned about increased risk of childhood cancer or lifetime risk?
Probably not: If you or your child's doctor are able, ask the radiology group where the ct scans were done about the dose of radiation. Higher radiation doses are associated with better resolution of the ct images, and so children's hospitals struggle with the trade off between radiation and great images. Likely your child's risk of cancer from the radiation of 2 scans is low. ...Read more
