CT scans of mummies show that plaque build-up and clogged arteries occurred among people 4,000 years ago, as well as today.

Reducing the CT colonography radiation dose from 120 kVp to 100 kVp resulted in a significant decrease in dose but minimal decrease in 3D image quality.

CT lung cancer screening could save up to 12,000 lives per year in the United States - and even more could be saved if the criteria were expanded.

CCTA is effective for determining heart attack risk in patients with suspected coronary artery disease - even if there are no treatable risk factors.
