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 ...
Other scans include CT of the abdomen and MRI. [45] 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
Transformation to hepatocellular carcinoma is more common in men. [2] Currently, if the hepatic adenoma is >5 cm, increasing in size, symptomatic lesions, has molecular markers associated with HCC transformation, rising level of liver tumor markers such as alpha fetoprotein , the patient is a male, or has a glycogen storage disorder , the ...
CT scan showing cholangiocarcinoma. Ultrasound of the liver and biliary tree is often used as the initial imaging modality in people with suspected obstructive jaundice. [49] [50] Ultrasound can identify obstruction and ductal dilatation and, in some cases, may be sufficient to diagnose cholangiocarcinoma. [51]
The intraperitoneal fluid, be it blood, ascites, or dialysate, collects in this space and may be visualized, most commonly via ultrasound or computed tomography (CT) scanning. As little as 30 or 40 ml of fluid in the abdominal cavity may be visualized in this space.
In terms of HCC diagnosis, it is recommended that people with risk factors (including known chronic liver disease, cirrhosis, etc.) should receive screening ultrasounds. If the ultrasound shows a focal area that is larger than 1 centimeter in size, patients should then get a triple-phase contrast-enhanced CT or MRI scan. [17]
NAFLD was defined by the presence of excess fat in the liver that cannot be explained by another factor, such as excessive alcohol use (>21 standard drinks/week for men and >14 for women in the USA; >30 g daily for men and >20 g for women in UK and EU, >140 g/week for men and >70 g/week for women in Asia-Pacific), liver injury caused by drugs ...
CT scan findings in a case of primary sclerosing cholangitis Ultrasound of sclerosing cholangitis in the common bile duct. PSC is generally diagnosed on the basis of having at least two of three clinical criteria after secondary causes of sclerosing cholangitis have been ruled out: [citation needed]
