However, this has been superseded by the use of the Couinaud classification which divides the liver into eight functional units (known as segments), supplied by individual segmental hepatic arteries, portal veins and bile ducts, which can be individually resected. Variation in hepatic arterial anatomy is seen in 40-45% of people. Classic branching of the common hepatic artery from the celiac artery, and the proper hepatic artery into right and left hepatic arteries to supply the entire liver, is seen in 55-60% of the population. Anatomic variants of the biliary and hepatic arterial anatomy are common, with the classic anatomy being found in only 58% and 55% of the population, respectively. Radiologists should be aware of anatomic variants in arterial supply, portal venous supply, and biliary drainage as these may affect treatment planning.

Such variants include diaphragmatic slips, “sliver of liver” (a leftward extension of the lateral segment of the left lobe), and variants related to the papillary process of the caudate lobe. The liver usually measures 7: craniocaudal length: 10-12.5 cm; transverse diameter: 20-23 cm; Segmental anatomy. Traditionally, the liver was divided into four anatomical lobes. Although numerous anatomical variants exist, in the majority of cases CE MRA allows a detailed depiction of the typical and atypical vascular anatomy of the splanchnic vessels [2, 11, 17, 33].
