  2. Ultrasonography of liver tumors - Wikipedia

    en.wikipedia.org/wiki/Ultrasonography_of_liver...

    Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...

  3. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.

    For example, because MRI has only been in use since the early 1980s, there are no known long-term effects of exposure to strong static fields (this is the subject of some debate; see 'Safety' in MRI) and therefore there is no limit to the number of scans to which an individual can be subjected, in contrast with X-ray and CT. However, there are ...

    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. [1]

    Chronic liver disease is rare in children and adolescents; however, congenital liver disorders are associated with an increased the chance of developing HCC. [21] Specifically, children with biliary atresia , infantile cholestasis , glycogen-storage diseases , and other cirrhotic diseases of the liver are predisposed to developing HCC in childhood.

    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 ...

    Liver cell adenomatosis is also associated with becoming hepatocellular carcinoma. [11] Like hepatic adenomas, they are diagnosed with imaging and biopsies as needed. Treatment of liver cell adenomatosis is difficult due to the multiple, widespread lesions. Liver imaging should be reviewed to see if it is possible to surgically remove the ...

  9. Molecular imaging - Wikipedia

    en.wikipedia.org/wiki/Molecular_imaging

    MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L which, compared to other types of imaging, can be very limiting. This problem stems from the fact that ...
