title: [Ultrasonographic aspects of liver segmentation].
abstract: BACKGROUND
  Current advances in hepatobiliary surgery (intrahepatic biliodigestive anastomosis, all types of hepatectomies, lobectomies and segmentectomies, liver transplantation, etc.), and improvements in imaging techniques, are encouraging research on the segmental anatomy of the liver. Couinaud's classification is most frequently used for identification of liver pathology in clinical practice. The aim of this review is to describe the clinical features of ultrasonographic identification of liver segments. COUINAUD'S LIVER SEGMENTS: There are eight liver segments described by this classification. Anatomical boundaries of liver segments are defined by ultrasonography, and this paper describes its morphology in detail.
  
  
  CONCLUSIONS
  It is of no doubt that ultrasonography has advantages over other diagnostic methods in examination of liver morphology. In fact, ultrasonography is a real-time, multiplanar, noninvasive, non-ionizing technique, and relatively easy to perform at low cost. Considering the advantages of diagnostic ultrasonography, keeping in mind the importance of preoperative topographic assessment of hepatic lesions, it appears that routine use of Couinaud's liver segmentation may be important in planning successful radical surgery.
