Virtual Precontrast Images-Dual Energy CT
An important clinical application of dual-energy CT is to generate pre-contrast images from a post-contrast dual-energy scan so that the pre-contrast scan can be avoided, potentially reducing radiation dose. The image quality and dose saving of Virtual non contrast technique depend on three factors: dose partitioning between the low- and high-energy scans, patient size, and spectra separation.

Hi,
Thanks for sharing these images. Maybe this will motivate others to try to reduce radiation dose to people being imaged.
Happy New Year and Kudos for this blog,
