title: Novel clinical applications of dual energy computed tomography.
abstract: Dual energy CT (DECT) was conceived at the very beginning of the computed tomography era. However the first DECT scanner was developed in 2006. Nowadays there are three different types of DECT available: dual-source CT with 80(100) kVp and 140 kVp tubes (Siemens Medical Solution); dual-layer multi-detector scanner with acquisition 120 or 140kVp (Philips Healthcare); CT unit with one rapid kVp switching source and new detector based on gemstone scintillator materials (GE Healthcare). This article describes the physical background and principles of DECT imaging as well as applications of this innovative method in routine clinical practice (renal stone differentiation, pulmonary perfusion, neuroradiology and metallic implant imaging). The particular applications are illustrated by cases from author's material.
