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.
