Virtual non-contrast images in photon-counting computed tomography: impact of different contrast phases
BackgroundPhoton-counting computed tomography (PCCT) enables new ways of image reconstruction, e.g. material decomposition and creation of virtual non-contrast (VNC) series with higher resolution and lower radiation dose than standard computed tomography (CT). Clinical experiences of this are limited.PurposeTo compare true non-contrast (TNC) series with VNC series derived from non-enhanced (VNCu),
