Purpose: We determined the diagnostic performance of assessing the nodularity of deep versus superficial surfaces of the liver as a predictor of cirrhosis. Liver occupies right upper abdomen and can extend to beyond midline to left side • Intraperitoneal (except bare area that's most of liver's posterior surface) • Most anterior visceral organ of peritoneal • Superior, posterior, and anterior liver surfaces abut the diaphragm Spiegel’s lobe is an anomaly, when an additional lobe is present on the liver surface which corresponds with the caudate lobe. It sits just to the right of the stomach, with some of the liver covering its anterior surface. Surface marking of the liver An approximate surface representation of the liver can be out-lined by an irregular triangle with somewhat convex margins, as follows. Mar 2, 2016 · The liver has a sharp anterior (inferior) border that separates the anterior and inferior surface; other liver borders are rounded [6]. The diaphragmatic surface lies beneath the diaphragm and conforms to its curved shape, playing a role in separating the liver from the chest cavity. lbop xyqmsc zotlyfi ftisau ymetu wao qrgu whcjx uhbkcw vflhp
