The liver span is a measurement performed during physical examination to determine the size of the liver and identify possible hepatomegaly.. It is the distance between the lower border of the liver in the mid-clavicular line obtained by palpation, and the upper border of the liver in the mid-clavicular line detected by percussion (the upper border of the liver lies behind the ribs and can not ...
A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12] There is considerable size variation between individuals, with the standard reference range for men being 970–1,860 grams (2.14–4.10 lb) [ 13 ] and for women 600–1,770 g (1.32–3.90 lb). [ 14 ]
In the axial plane, the caudate lobe should normally have a cross-section of less than 0.55 of the rest of the liver. [2] Other ultrasound studies have suggested hepatomegaly as being defined as a longitudinal axis > 15.5 cm at the hepatic midline, or > 16.0 cm at the midclavicular line. [17] [18]
Ranges of healthy body roundness have been established to accurately classify people with healthy fat mass compared to obese people who are at risk for morbidities. [ 1 ] Compared to traditional metrics, such as the body mass index (BMI), (which uses weight and height), BRI may improve predictions of the amount of body fat and the volume of ...
It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver). [3] The duct is about 3 cm long. [4] The common hepatic duct is about 6 mm in diameter in adults, with some variation. [5]

Liver size can be enlarged, normal, or shrunken in people with cirrhosis. [36] As the disease progresses, the liver will typically shrink due to the result of scarring. [37] Jaundice is the yellowing of the skin. It can additionally cause yellowing of mucous membranes notably of the white of the eyes.
This location of suddenly increased auscultation volume is marked as the inferior edge of the liver and can then be used to determine the overall liver size. Multiple variations on the exam also exist including different stethoscope placements such as over the costal margin or liver, percussing the abdomen instead of scratching, or scratching ...
