Tiny, shallow grooves on the surface of the brain may provide new insight into how aging and Alzheimer’s disease affect brain structure and cognitive function. A new study published in The Journal of ...

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 ...

It's also important to recognize that CT scans use ionizing radiation to create images, and ionizing radiation—especially if the scan uses a high dose of radiation or a patient gets repeated ...

Researchers projected CT use in 2023 would lead to more than 100,000 future cancer diagnoses, and if trends continued, may account for 5% of new cases annually in the U.S., according to study ...

New research reveals CT scans may cause 5% of U.S. cancer cases annually. Learn the risks, who's most vulnerable, and how to protect yourself.

A new study suggests the cancer risk from radiation emitted by the CT machine during a scan could be higher than previously thought — up to 103,000 cases from the 93 million scans performed in 2023.

A brain scan, the website shows, can emit as little radiation as 200 dental X-rays or as much as 1,600. The radiation dose from an abdominal scan for a suspected kidney stone can be as low as 100 ...

CT scans diagnose afflictions from tumors to kidney stones to life-threatening diseases and injuries, such as aneurysms and blood clots leading to stroke. But the radiation emitted by this essential ...

Patients who underwent at least one head/neck CT scan exhibited significantly higher risk for childhood brain tumors as those who did not undergo head/neck CT scans (OR = 2.84; 95% CI, 1.12-7.19).

A CT of the brain is a noninvasive diagnostic imaging procedure that uses special X-rays measurements to produce horizontal, or axial, images (often called slices) of the brain. Brain CT scans can ...

What is a brain perfusion scan? A brain perfusion scan is a type of brain test that shows the amount of blood taken up in certain areas of your brain. This can provide information on how your brain is ...
