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

Can CT scans accurately detect arteriosclerosis?

OnlyAfterLongEnough: Atherosclerosis, known to start ~age 7 on average, & microcalcifications (within artery wall smooth muscle cells just outside the plaque) can be seen with a microscope & ca+2 stains within early years but are too small to see with any current ct machines. These may become visible by the best ct machines by early 30's, 2 decades later but typically a decade before obvious clinical events & symptoms. ...Read more

How bad would it be to have two CT scans of the chest in a month?

How bad would it be to have two CT scans of the chest in a month?

If the CT scans: are medically necessary, then the benefit outweighs the small theoretical risk. For two standard chest CT scans, the theoretical additional lifetime cancer risk is 0.08% or about 1 in 1130. You can calculate the risks of various radiology studies with an interactive tool at xrayrisk.com ...Read more

How dangerous would it be to have two CT scans of the chest in a month?

V. minor cancer risk: The cancer risk from an additional CT is quite low when compared to the lifetime risk of getting cancer from all causes. But, the most widely accepted model for cancer risk from ionizing radiation (as from CTs) assumes that each study incrementally adds additional risk. For younger people the risk is increased, I would talk to your doctor to make sure that the additional CT is really necessary, ...Read more

Can you let me know how many mris or CT scans can you get without it being considered unsafe?

No Set Limit: There is no radiation associated with the MRI scans so there should be no concern on that score. As far as ct scans go, the consideration is a valid indication for getting the exam done. Is the small additional risk of the exam warranted by the benefit of the study? That is a question for your doctor to decide with you. ...Read more

I'm 24 and had 4 CT scans in the last 5 years. Are these dangerous at my age if i get another CT scan and end up needing one every few years?

Weigh risks/benefits: There is quite a bit of radiation exposure with ct scans, so they should not be done lightly. Whether or not to have future cts depends on why you are having them. If you have some potentially life threatening condition that requires periodic ct scans, it might be worth the risk. Only have them if you really need them. See http://bit.Ly/t1rbrc. ...Read more

Caution: A ct abdomen equals about 500 chest xrays, add a pelvis, another 500. This is 5 years background radiation and exposure is cumulative. Worse when young! think twice about the real need before doing xrays.
