Oncology poised to gain from perfusion studiesStroke is typically the headline application in all discussions of perfusion CT. Now interest in this technique is growing from a very different direction: oncology imaging. Speed, spatial resolution add clinical detail to CTACardiovascular imaging has much to gain from developments in CT. The improved temporal and spatial resolution has already translated into superior image quality. Now the radiology community is waiting to see whether the promises made by proponents of dual energy—that it can remove calcified plaques from coronary CT angiography studies—will be kept. Rapid scanning shows benefits in cardiac CTThe clinical impact of new technology is often difficult to quantify. In cardiac CT, however, the connection between diagnostic performance and latest generation scanning technology is crystal clear. CT takes different directions to tackle age-old problemsThe future of CT used to be easy to predict. So-called slice wars dominated the discussion as vendors wheeled out their latest multidetector machines. CT systems were ranked according to a kind of geometric progression: single-slice, two-slice, four-slice, 16-slice . . . It was a simple form of classification and one that was easy to appreciate.
