The success of surgical and transarterial therapies for hepatocellular carcinoma relies on hepatic hemodynamics. Non-contrast 4D flow MRI can quantify hepatic blood flow at the lobar arterial and portal vein levels with a low relative error and clearly evaluate portosystemic shunts; however, segmental flow quantification remains limited. By pairing 4D flow MRI with HCC surveillance MR imaging, lobar flow per volume can also be assessed, providing valuable information for surgical planning.
