Basic principles and postprocessing techniques of dual-energy CT: illustrated by selected congenital abnormalities of the thorax.
Recent technologic advances in multidetector computed tomography have allowed the performance of simultaneous acquisition dual-energy computed tomography (DECT). The advantages of this new technique include simultaneous visualization of lower voltage tube images with improved iodine conspicuity and the performance of material specific imaging, which attempts to differentiate specific materials in the generated images. In this article, we review the concepts and physical principles of DECT using congenital thoracic abnormalities as a substrate for depicting the versatility of DECT.
