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.
