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...
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...
Among those undergoing CT imaging in our ED, high-exposure patients (greater than ten scans) constituted a significant minority, while more than one in four patients underwent more than one CT scan during the study period. While the presumed overall risk of radiation-induced cancer continues to ...
Over one million European children undergo computed tomography (CT) scans annually. Although moderate- to high-dose ionizing radiation exposure is an established risk factor for hematological malignancies, risks at CT examination dose levels remain uncer

he took one look at me and said that I was the classic Cushing’s case. Then he went on to explain it to me. This was in Nov.1989. The tests began and I had a CT Scan done in Dec of that year that I didn’t get the results from until after Christmas. They showed a tumor ...
Too much radiation raises the risk of cancer. That risk is growing because people in everyday situations are getting imaging tests far too often. Like the New Hampshire teen who was about to get aCT scanto check for kidney stones until aradiologist, Dr. Steven Birnbaum, discovered he'd alre...
Hodgkin lymphoma in studies that combined patients across age groups, there was a 3-fold increased risk of the disease for patients between the ages of 36 and 45 years who had undergone CT scans. There was no observed CT scan–associated increased risk for non-Hodgkin lymphoma in older ...
This can result in a higher effective dose compared to the same scan in adults. The most useful means of assessing the radiation risk to a particular body area is the effective dose, expressed in millisieverts (mSv). The effective dose has been defined by the International Commission on ...
