“…However, conven-tional CT imaging techniques struggle to distinguish soft tissues without the use of the X-ray attenuating contrast media, which can present challenges when detecting liver tumors from surrounding normal tissues. [12][13][14][15] Dual-energy CT (DECT) is a type of spectral CT that has garnered considerable attention in recent years. By rapidly switching between high and low energy spectra, DECT generates monochromatic energy images, material decomposition images, energy spectrum curves, and effective atomic number maps, thereby overcoming beam-hardening artifacts.…”
