By Genevra PittmanNEW YORK (Reuters Health) - One-third of people getting a CT scan didn't know the test exposed their body to radiation, in a new study from a single U.S. medical center.Researchers found the majority of patients also underestimated the amount of radiation delivered by a...
An X-ray for knee pain. A CT scan for a head injury. Mammograms every other year, starting at age 50. Over a typical lifetime of radiation exposure from medical tests, a person can start to wonder: How much is too much? There’s no formula for answering that, experts say, in part...
Objective: This study aimed to evaluate the necessity rate of requested head CT scans for traumatic patients and to ultimately estimate the risk of radiation-induced brain cancer. Material and Methods: In this retrospective analytical study, traumatic patients, who had undergone a head CT scan in ...

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 of 'natural background radiation' (even this amount isn't considered dangerous).An...
A CT scan exposes your body to some radiation. That involves a small amount of risk, and it’s important to understand the issues. Types of Radiation A CT scan uses what’s called “ionizing” radiation. It’s powerful enough to pass through your body to create clear images on a compute...
