  2. Ultrasonography of liver tumors - Wikipedia

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

    A similar procedure is transarterial embolization but without chemotherapeutic agents injection, used in the treatment of hypervascular liver metastases. These therapies are based on the predominantly arterial vasculature of HCC and hypervascular metastases, while the remaining liver parenchyma has a dual vascular intake, predominantly portal.

  3. Percutaneous transhepatic cholangiography - Wikipedia

    Some uses for this procedure includes: drainage of bile/infected bile to relieve obstructive jaundice, to place a stent to dilate a stricture in the biliary system, stone removal, and rendezvous technique [4] where guidewire from the common bile duct (CBD) meets with duodenoscope (coming from the oesophagus into the stomach and then duodenum) at the major duodenal papilla.

  4. Liver biopsy - Wikipedia

    en.wikipedia.org/wiki/Liver_biopsy

    Occasionally, liver biopsy is required to monitor the progress of treatment, such as in chronic viral hepatitis. [1] It is an effective way to measure changes in the Ishak fibrosis score. [3] For the last century liver biopsy has been considered as the gold standard for assessing the stage and the grade of chronic liver disease.

  5. Abdominal ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Abdominal_ultrasonography

    Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).

  6. Chronic liver disease - Wikipedia

    en.wikipedia.org/wiki/Chronic_liver_disease

    Testing for chronic liver disease involves blood tests, imaging including ultrasound, and a biopsy of the liver. The liver biopsy is a simple procedure done with a fine thin needle under local anaesthesia. The tissue sample is sent to a laboratory where it is examined underneath a microscope. [3]

  7. Transjugular intrahepatic portosystemic shunt - Wikipedia

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

    A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.

  8. Hepatocellular carcinoma - Wikipedia

    en.wikipedia.org/wiki/Hepatocellular_carcinoma

    On ultrasound, HCC often appears as a small hypoechoic lesion with poorly defined margins and coarse, irregular internal echoes. When the tumor grows, it can sometimes appear heterogeneous with fibrosis, fatty change, and calcifications. This heterogeneity can look similar to cirrhosis and the surrounding liver parenchyma.

  9. Cholangiography - Wikipedia

    en.wikipedia.org/wiki/Cholangiography

    Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP). Although this is a form of imaging, it is both ...
