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 ...
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]
Liver: Hepatomegaly: ... About 13% of normal healthy adults have a transverse pelvic diameter of over 10 mm. ... 2.0 cm in width and 1.2 cm in thickness. [34] Ureter:
It is unique or paucilocular. It can be associated with other types of benign liver tumors. Characteristic 2D ultrasound appearance is that of a very well defined lesion, with sizes of 2–3 cm or less, showing increased echogenity and, when located in contact with the diaphragm, a "mirror image" phenomenon can be seen.
The liver is a dark reddish brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12]
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 ...
An enlarged spleen, which normally measures less than 11–12 cm (4.3–4.7 in) in adults, may suggest underlying portal hypertension. [67] Ultrasound may also screen for hepatocellular carcinoma and portal hypertension. [45] This is done by assessing flow in the hepatic vein. [68] An increased portal vein pulsatility may be seen.
Ultrasonography of the liver with some standard measurements [6] In patients with deranged liver function tests, ultrasound may show increased liver size (hepatomegaly), increased reflectiveness (which might, for example, indicate cholestasis), gallbladder or bile duct diseases, or a tumor in the liver.
