1) Dual energy CT allows for the creation of virtual non-contrast (VNC) and iodine overlay images, which can quantify the enhancement of a lesion with a single acquisition. 2) Analysis of iodine overlay and VNC images can accurately characterize a variety of incidental lesions encountered with routine CT imaging in the Emergency Department, including adrenal, renal, splenic, and pancreatic lesions.  3) Routine dual energy CT imaging and post-processing can be performed in the Emergency Department setting, and has the potential to eliminate the need for follow-up imaging in many patients.   

1) Dual energy CT technology - Illustrate the basic principles of material decomposition with dual energy CT. 2) Applications to incidental lesions in the Emergency Department - Review of common incidental lesions encountered with routine CT imaging in the Emergency Department, and potential applications of dual energy post-processing techniques. - Case based review correlating dual energy CT post-processing analysis of common incidental lesions encountered in the Emergency Department with other imaging modalities including multi-phase CT, MRI, and ultrasound.
