  2. Transjugular intrahepatic portosystemic shunt - Wikipedia

    en.wikipedia.org/wiki/Transjugular_intrahepatic...

    An interventional radiologist creates the shunt using an image-guided endovascular (via the blood vessels) approach, with the jugular vein as the usual entry site. The procedure was first described by Josef Rösch in 1969 at Oregon Health and Science University.

  3. Ultrasonography of liver tumors - Wikipedia

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

    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.

  4. Cirrhosis - Wikipedia

    en.wikipedia.org/wiki/Cirrhosis

    Cirrhosis is more common in men than in women. [156] The cost of cirrhosis in terms of human suffering, hospital costs, and lost productivity is high. Globally, age-standardized disability-adjusted life year (DALY) rates have decreased from 1990 to 2017, with the values going from 656.4 years per 100,000 people to 510.7 years per 100,000 people ...

  5. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

  6. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    Ultrasound image showing the liver, gallbladder and common bile duct. Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women. Uses of ultrasound are much broader, however.

  7. Hepatocellular carcinoma - Wikipedia

    en.wikipedia.org/wiki/Hepatocellular_carcinoma

    High intensity focused ultrasound (HIFU) (as opposed to diagnostic ultrasound) is an experimental technique which uses high-powered ultrasound waves to destroy tumor tissue. A systematic review assessed 12 articles involving a total of 318 patients with hepatocellular carcinoma treated with Yttrium -90 radioembolization. [ 84 ]

  8. Focused ultrasound - Wikipedia

    en.wikipedia.org/wiki/Focused_ultrasound

    These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [31] [32] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [1] [33] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.

  9. Contrast-enhanced ultrasound - Wikipedia

    en.wikipedia.org/wiki/Contrast-enhanced_ultrasound

    The ultrasound system converts the strong echogenicity into a contrast-enhanced image of the area of interest, revealing the location of the bound microbubbles. [12] Detection of bound microbubbles may then show that the area of interest is expressing that particular molecular marker, which can be indicative of a certain disease state, or ...
