There are no known health risks associated with having an MRI scan.How much?A CT scan A CT scan produces around 7 mSv, or around the same amount of radiation as you'd expect to absorb if you spent a year in Cornwall, where the sun exposure and radioactive rocks pump up the levels ...

also expose patients to ionizing radiation, CT has appropriately received the greatest scrutiny because of the relatively high radiation dose per exam – although it comprises about 15% of all medical imaging procedures, it produces approximately half of the population's medical radiation exposure [4...
Measurements of radiation exposure during routine CT scanning were found to average 4.2 R at the level of the ocular lens. This data was combined with CT scanning rate data from a sample of 100 patients followed in the myelomeningocele clinic. The number of scans averaged 7.75/patient with a...

with CT. Referring emergency physicians were also largely unaware that there were any potential harmful effects from the radiation exposure, with only 9% aware of the increased cancer risk. Of even greater concern is the fact that the majority of the radiologists performing the CT examinations ...
which gives us extra radiation exposure. With all of this—on top of the radiation exposure we get from sources other than flying, such as X-rays, CT scans, MRIs, devices such as cell phones, and even food and water—if we can take a step to protect our health, well-being, and vit...
BackgroundVariability in radiation exposure from CT scans can be appropriate and driven by patient features such as body habitus. Quantitative analysis may be performed to discover instances of unwarranted radiation exposure and to reduce the probability of such occurrences in future patient visits. No...
