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 complete blood test can help distinguish intrinsic liver disease from extrahepatic bile-duct obstruction. [19] An ultrasound of the liver can reliably detect a dilated biliary-duct system, [20] it can also detect the characteristics of a cirrhotic liver. [21] Computerized tomography (CT) can give accurate anatomical information for a complete ...
The cause of liver hemangiomas remains unknown; however, it may have congenital and genetic components. [5] They are not known to become malignant based on the available existing literature. [5] Liver hemangiomas do not usually cause symptoms. [2] [5] They are usually small, with sizes up to 10 centimeters. [5] Their size tends to remain stable ...
The liver, viewed from above, showing the left and right lobes separated by the falciform ligament. 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]
CT scanning can perform a virtual colonoscopy with greater accuracy and less discomfort for the patient than a traditional colonoscopy. [143] [144] Virtual colonography is far more accurate than a barium enema for detection of tumors and uses a lower radiation dose. [145] CT is a moderate-to-high radiation diagnostic technique.
A CT scan is non-invasive and may be helpful in the diagnosis. [45] Compared to the ultrasound, CT scans tend to be more expensive. MRI provides excellent evaluation; however, is a high expense. [45] Liver cirrhosis on CT imaging of the abdomen in transverse view
Ultrasonography of liver tumors involves two stages: detection and characterization. [1]Tumor detection is based on the performance of the method and should include morphometric information (three axes dimensions, volume) and topographic information (number, location specifying liver segment and lobe/lobes).
The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells.
