Abstract
With advances in imaging and surgical techniques, the diagnosis and
treatment of primary and secondary liver neoplasms have improved. Advances
in imaging have contributed to the early detection of the tumors and have
allowed more precise preoperative characterization and localization of the
lesions. Refinements in surgical technique have permitted more extensive
resections, while at the same time placing even greater importance on
accurate preoperative imaging of the tumor. Presurgical planning requires
precise definition of the extent of the tumor vis-a-vis hepatic segmental
anatomy. The goal of this essay is to discuss the segmental anatomy of the
liver, the types of segmental resections possible, and the strengths and
weaknesses of the various imaging techniques used in the preoperative
assessment of potential candidates for hepatic resection. Staging of
hepatic malignant tumors and technical details of the imaging techniques
are not discussed.
