Low-Dose CT Beats X-Ray in Lung Cancer Detection

2014 05 Sep

Ultra-low-dose computed tomography (CT) technology worked better than x-ray examination in detecting lung cancer, according to results of a pilot study conducted in Norway. Researchers tried to determine which imaging modality works best for the diagnosis of lung cancer by evaluating both x-ray images and ultra-low-dose CT scans of a small sample of... Read more

Children’s Heart Imaging-Associated Cancer Risk Initially Low

2014 10 Jun

The levels of low radiation, which children with heart disease are exposed to during X-rays, does not increase their lifetime cancer risk in a significant way, however as they undergo further complex imaging examinations involving higher radiation doses, the risk of cancer does increase slightly. These are the findings of a study conducted by... Read more
