Researchers perfect the view of heart disease

"Radiologists have developed a way to gain better insight into signs of heart disease by using cardiac CT scans that detect narrowed arteries and low blood flow. CT scans use X-rays to create cross-sectional images of the body's internal anatomy. The scans can detect blockages in coronary arteries, but it's hard to tell if they're actually preventing blood from flowing to the heart.
