Cardiac imaging researchers are validating broader clinical roles for 64- slice and dual-source CT while introducing the radiological world to even more powerful machines that promise to lower radiation exposure and improve resolution.

Coronary heart disease is one of the leading causes of morbidity and mortality in developed countries.1 Accurate detection of early cardiac disease is of utmost importance for the delivery of appropriate treatment.

Interest in cardiac imaging with multislice CT is growing, as evidenced by the large number of studies that have been published on this topic. Advances in cardiac MSCT have also been aided by the introduction of extremely fast, user-friendly scanners.

Photon-counting, x-ray tubes, antiscatter grids, and 3D imaging all offer approaches that may lower exposure for patients

The increasing use of multislice CT has raised questions about patients' rising radiation burden. But CT can-and should-be a low-dose modality, according to Prof. Dr. Willi Kalender, director of the Institute of Medical Physics at the University of Erlangen in Germany.
