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.

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 ...

Adults, however, may face a greater risk since most scans are performed on them. The most common cancers linked to CT scan exposure include lung, colon, bladder cancer, and leukemia.

A CT scan is a type of imaging test that lets your doctor look inside your body. Remember, your doctor wants you to feel “prepared and comfortable for your exam,” Smith-Bindman said.

The study itself is basically a modeling exercise. The authors took an estimate of the number of CT scans done every year in the U.S., based on research from 2023. Next, they estimated the dose of ...

Based on the number and types of scans people underwent in 2023, the researchers estimated that around 103,000 U.S. cancer diagnoses per year could soon be attributed to CT scan radiation exposure.

CT scans performed in the US in 2023 alone could eventually lead to over 100,000 extra cancer cases, a new study claims.

In 2023 alone, Americans underwent 93 million CT scans, a figure that researchers say could result in nearly 103,000 new cancer cases – three to four times higher than previous estimates.

They estimated that the use of CT scans in 2023 would cause 102,700 lifetime cancers, including 93,000 cancers in adults and 9700 cancers in children.

Since 2007, use of CT scans has increased 35 percent, an increase not entirely explained by population growth, they note. Outside experts agreed that CT scans should be used judiciously.
