[Volumic and multislice CT: principles, applications and future prospects].

The introduction of new array detector technology for multislice CT improves CT-scan capabilities. This technique offers significant advantages including improved temporal and spatial resolutions, retrospective determination of slice thickness, shorter acquisition time, and contrast media saving. The most recent improvements lead to high quality cardiac and vascular examinations. The main principles of this technique are explained and its diagnostic as well as its economic impacts are discussed.
