Low-dose chest CT scans don't appear to damage human DNA, a new study shows.
The U.S.-based National Lung Screening Trial, conducted between 2002 and 2010 and involving more than 53,000 heavy and former smokers, revealed that these chest scans can significantly cut lung cancer deaths compared to chest X-rays. They do so by finding cancers at an earlier stage, researchers explained.
CT lung cancer screening can detect other serious smoking-related conditions, such as heart disease, osteoporosis and emphysema, researchers say.
Medical experts consider lung cancer screening an effective way to detect malignant tumors at earlier, more treatable stages. Now, new research suggests low-dose CT scans of the lungs could also improve diagnosis and treatment of other smoki...
Despite efforts from medical groups to cut down on the overuse of CT scans and MRIs for safety reasons, their use has instead increased, a new study shows.
"Medical imaging is an important part of health care and contributes to accurate disease diagnosis and treatment, but it also can lead to patient harms such as incidental findings, overdiagnosis, anxiety and radiation exposure that...
Use of risky CT scans during pregnancy has risen significantly in North America in the past two decades, a new study finds.
"It's important to quantify exposure to ionizing radiation because it can cause cancer and birth defects, and should be kept to a minimum, especially during pregnancy," said co-lead author Marilyn Kwan. She's a senior research scientist at Kaiser Permanente North...
The underpinnings of autism may lie in an unexpected part of the brain, a small study suggests.
Scientists conducted brain scans on 20 boys with autism and 18 boys without the neurodevelopmental disorder. The scans showed that boys with autism had a significantly flatter surface on the right side of their cerebellum. That side happens to be involved in language processing.
