Next generation imaging may reduce radiation exposure

The next generation of imaging used to detect heart disease is not only more accurate, but seems to drastically reduce radiation exposure.

The standard 64-slice CT scans can image 4 centimeters at a time. Researchers at Columbia University tested the latest technology, which uses 320-slice scans to image 16 centimeters. That's the entire length of the heart in less than half a second.

Doctors say the new CT scans expose patients to as much as 90% less radiation than current scans.

This study was done using special mannequins. Much more research is necessary before this would become mainstream.
