CT scans are a common test used by radiologists to examine what's happening inside the body. These scans use a small amount of radiation, raising concerns that they could cause cancer. Mark Supanich, ...

Medical imaging scans that create detailed images of the body’s internal structures are widely used in medicine. Doctors need them to detect and manage certain types of cancer, assess the extent of ...

Computed tomography (CT) examinations (known more commonly as a “CT scan” or “CAT scan”) incorporate a series of x-ray images taken of areas inside the body and use a computer to create a ...

Do CT scans raise your risk of cancer? A new study weighs in. Radiation is everywhere—in the air we breathe, the water we drink, the walls of our homes and offices, emanating from microwaves, at the ...

A research team has developed a versatile machine learning model that could one day greatly expand what medical scans can tell us about disease. Scientists used their tool, named Merlin, to assess 3D ...

A new analysis estimates that more than 100,000 cancer cases per year could be caused by radiation from CT scans. In some cases, the information provided by a CT scan could also be obtained from other ...

NPR's Ayesha Rascoe asks Dr. Rebecca Smith-Bindman about her research indicating CT scans, which emit radiation, will cause some 100,000 cases of cancer annually. X-rays and CT scans have ...

CT scans, or CAT scans, are widely used to get internal images of the body and diagnose dangerous medical conditions — but they could pose a hidden risk. A new study from the University of California ...

A new study has set off alarm bells, attributing the overuse of computed tomography – or CT – scans to around 5% of new cancer diagnoses annually. Since 2007, this imaging technology has seen a 30% ...
