A new multicenter study related to QP-Liver confirms the robustness of MRI-based fat and iron quantification. The research shows that including or excluding hepatic vessels in automated whole-liver segmentation leads to no clinically significant differences in PDFF and R2* measurements, while vessel exclusion slightly improves biomarker precision. These findings reinforce confidence in automated imaging tools and support accurate, non-invasive assessment of patients with chronic liver disease in both clinical practice and research settings.
