When appendicitis is suspected, doctors typically perform a combination of physical exams, blood work, and imaging tests such ...

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 scans — ...

They can be life-saving but radiation from the scans also contributes to cancer risk. The authors of a new study estimate overuse of CT scans is increasing the U.S. cancer burden.

CT angiography sensitivity ranged from 75.5–87.3%, while specificity held near 90% across scales. Sensitivity refers to how well a test finds its target, in this case, brain death.

But if a CT scan is ultimately deemed to be the best tool—and, to be clear, in certain circumstances it is—then I would not resist getting it out of fear for the small increased lifetime risk ...

A CT scan offers doctors a picture of the brain and skull. It can help doctors to determine if there’s any blood leaking around the brain, and indicate the presence of a brain aneurysm.
