Spectral Computed Tomography: Influence of Contrast Medium for Calculation of Virtual Noncontrast-enhanced Images
The article is focused on the influence of contrast medium for calculation of virtual non-contrast-enhanced images (VNC) by spectral computed tomography (CT). True non-contrast-enhanced images (TNC) are we...
