Robust Liver Steatosis Quantification Using Photon-Counting CT in Comparison to PDFF: Validation across Protocols and Cohorts.
RATIONALE AND OBJECTIVES To evaluate the robustness and grading performance of Photon-counting CT (PCCT)-derived fat fraction (CTFF) in liver fat quantification across different protocols and cohorts with varying liver conditions, using proton density fat fraction (PDFF) as the reference. MATERIALS AND METHODS The pr...
