Objective:

To compare arterial- and portal venous phase–derived virtual non-contrast (VNC) images from dual-layer spectral CT (DLCT) with standard true non-contrast (TNC) images in terms of image quality and abdominal lesions and calcifications measurements, highlighting the significance of this comparison.

Key Findings:
  • VNC images derived from arterial and portal venous phases were evaluated against TNC images for accuracy in lesion characterization.
  • The study aimed to assess the potential of VNC images to replace TNC images in routine abdominal CT protocols.
Interpretation:

Limitations:
  • The study was conducted at a single center, which may limit generalizability.
  • Exclusion criteria may affect the applicability of findings to broader patient populations.
Conclusion:

The findings will help evaluate the feasibility of using VNC images in routine abdominal CT protocols without suggesting implications.
