DLIR/dual-energy CT non-inferior to MRI for HCC LI-RADS major features

DLIR-H/50-keV dual-energy CT protocol showed non-inferiority to MRI for detecting arterial phase hyperenhancement (APHE) and washout in HCC, offering an alternative when MRI access is limited.

• DLIR-H/50-60-keV yielded best quantitative metrics (noise, SNR, lesion-to-liver contrast; all p<0.05) in a comparison of 36 image sets per patient across four keV levels and three reconstruction algorithms.
• The single-center study retrospectively analyzed a prospective cohort, using semi-quantitative scoring of LI-RADS 2018 features to establish non-inferiority to MRI.
