Virtual unenhanced (VUE) image reconstruction techniques have the potential to eliminate the need for the acquisition of a non-contrast exam in imaging protocols that currently require both contrast and non-contrast computed tomographic (CT) scans. Here, we propose a new physically meaningful approa...
