Radiation is everywhere—in the air we breathe, the water we drink, the walls of our homes and offices, emanating from microwaves, at the dentist, and at the doctor if we break a bone. And we’re told, ...

More Americans are receiving computed tomography (CT) scans than ever before, and while this technology can save lives, some scientists are concerned that low doses of ionizing radiation could ...

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% ...

Other experts say the risk of cancer from CT scans is minimal, and these imaging exams are an important diagnostic tool for various cancers. A commonly used computerized scan may slightly increase ...

A new study reveals that abdominal CT scans play a significant role in diagnosing sarcopenia, a potentially reversible muscle-wasting condition that affects millions of older adults. Sarcopenia is ...

A hot potato: A new study from UC San Francisco is raising alarms about the widespread use of computed tomography (CT) scans in the United States, warning that the technology may be responsible for as ...

A population-based cohort study evaluated the risk for spontaneous pregnancy loss and congenital anomalies in offspring of women exposed to computed tomography (CT) ionizing radiation before ...

Archaeopteryx is the fossil that proved Darwin right. It’s the oldest known fossil bird, and it helps show that all birds— including the ones alive today— are dinosaurs. And while the first ...
