The findings of large studies of patients who have experienced a CT scan at a young age are starting to become available鈥攕tudies of infants, children and adolescents are a sensible starting point because the risk of radiation-induced cancer is generally greater at younger ages at ...
The major risk for this procedure is exposure to radiation. There are higher doses of radiation delivered with a CT scan than with an x-ray. The higher doses help to produce more detailed pictures, which in turn help make correct diagnoses. ...
This factor may underlie the results that the risk of cancer from CT radiation does not continue to decrease with age. This may also explain why cancer risks in the 45–65 years group are less sensitive to radiation exposure than those in the < 45 years group. Despite the age ...
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

CT scan is a very low-risk procedure. The patient will be exposed to radiationwhen undergoing a CT scan. However, it is a safe level. The biggest potential risk is with a contrast (also called dye) injection that is sometimes used in CT scanning. This contrast can help distinguish normal...
CT scan of the Arm or Leg is done to look for problems such as fracture etc. in the shoulder, wrist, elbow, hand, knee, hip, ankle, or foot. What are the Risks of CT Scan? CT scan is a safe, non-invasive and a very low-risk procedure. The patient gets exposed to radiation wh...
