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]
Curative therapy is indicated in early stages, which include very early stage (single nodule <2 cm), curable by surgical resection (survival 50-70% five years after surgical resection) and early stage (single nodule of 2–5 cm, or up to 3 nodules <3 cm) which can be treated by radiofrequency ablation (RFA) and liver transplantation.
Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).
Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
The cell survival curve is a curve often used in radiobiology that represents the relationship between the amount of cells retaining reproductive capabilities and the absorbed dose of radiation from said cells. Tumor cells are able to grow infinitely, while normal cells must undergo treatment in order to grow indefinitely (see Cellular ...
The rates of nonalcoholic fatty liver disease — which can lead to life-threatening conditions, including cirrhosis and cancer of the organ — have been soaring over the past three decades, a ...
Focal nodular hyperplasia is not a neoplasm; it is believed to result from localized hyperplastic hepatocyte response to an underlying congenital arteriovenous malformation. [2] It consists of normal liver constituents in an abnormally organized pattern, grows in a stellate pattern and may display central necrosis when large. [5]
The latter is an FDA-approved treatment for primary liver cancer which has been shown in clinical trials to increase the survival rate of low-risk patients. SIR-Spheres are FDA-approved for the treatment of metastatic colorectal cancer , but outside the US, SIR-Spheres are approved for the treatment of any nonresectable liver cancer including ...
