Abstract
Dual energy CT has been possible since last decade and has demonstrated considerable advantages in clinical diagnosis. DECT is achieved by ways that are unique to different CT platforms. DECT is considered as a first step towards achieving true “Spectral CT”. There are numerous applications including improved lesion detection and characterization, artifacts reduction and possible quantification of CT images. Advanced applications such as kidney stone classifications, gout detection, automatic bone removal, virtual non-contrast enhanced images and many others are routinely used clinically. In spite of these advantages, DECT is still not used widely in clinics. Factors includes multiple data sets, additional time for image processing, no financial incentives for reviewing multiple data sets of DECT compared to conventional CT data sets. This presentation will discuss the many factors that are holding this technology from wider acceptances.
