OBJECTIVE: The purpose of this article is to describe the role of cross-sectional imaging before portal vein embolization, the normal imaging findings after the procedure, and the imaging findings of postprocedural complications. CONCLUSION: With the increasing emphasis on aggressive resection of hepatic malignancies, portal vein embolization has evolved into a leading technique. Radiologists need to be familiar with the normal imaging findings after this procedure and with the imaging findings of postprocedural complications.
