In addition, discrimination of synchronous lesions that have a different nature is also important knowing that up to 25–50% of liver lesions less than 2 cm detected in cancer patients may be benign . US sensitivity for metastases detection varies depending on the examiner's experience and the equipment used and ranges between 40 and 80% .
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 ...
When imaging the liver with ultrasound, large lesions are likely to be HCC (e.g., a mass greater than 2 cm has more than 95% chance of being HCC).Given the blood flow to the liver, HCC would be most visible when the contrast flows through the arteries of the liver (also called the arterial phase) rather than when the contrast flows through the ...
The ultrasound showed three lesions on Violette's liver, initially prompting the team to schedule an MRI for the baby. ... though she says the professionals "dismissed" her worries and explained ...
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.

Ultrasound of malformed vessels within the fibrous scar of focal nodular hyperplasia. Liver tumor types by relative incidence in adults in the United States, with focal nodular hyperplasia at right. [3] Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases.
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.
Liver diseases, including conditions such as non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ALD), and viral hepatitis, are significant public health concerns worldwide. In the United States, NAFLD is the most common chronic liver condition, affecting approximately 24% of the population, with the prevalence rising due ...
