Each year, the US performs more than 93 million computed tomography (CT) scans, many of which offer limited clinical value. For patients with mild head injuries, CT scans are often ordered reflexively ...

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 ...

About 40% of cancers among Americans can be attributed to potentially modifiable factors such as smoking, drinking, obesity, and physical inactivity. If a widely reported study from earlier this year ...

While these advanced imaging tools save lives by detecting injuries and illness, mounting evidence suggests they may come with long-term consequences that patients need to understand before agreeing ...

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 ...

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 ...

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% ...

A research team funded by the National Institutes of Health (NIH) has developed a versatile machine learning model that could one day greatly expand what medical scans can tell us about disease.

Computed tomography (CT) scans could soon account for 5 percent of all new cancer cases diagnosed annually if current practices persist, a new study has concluded. That sounds scary; but how serious ...
