Letter from the Editor: Interesting Facts about the Liver
The Anglo-Saxon word for liver, lifer, suggests that the etymology of the word is somehow related to “life.”1 Further, the German word for liver is die Leber, and the German verb leben is “to live.” Hepar is the Greek term for liver and the source of words such as hepatic, hepatitis, and heparin (which was first isolated from the liver cells of dogs). Beyond the origin of its name there are numerous other interesting facts about the liver. Test your knowledge of the liver by answering the following questions. (Source: Seminars in Roentgenology)

Cardiac Infections
Cardiac infections comprise a broad range of clinical and radiologic entities, which can involve the pericardium, myocardium, valves, or endocardium. They can arise in these cardiac structures or result from spread of infection from contiguous structures or implanted material (vascular grafts and prosthetic cardiac valves).

Elastography of Diffuse Liver Diseases
Liver fibrosis is a common pathway in multiple liver diseases, including viral (hepatitis B virus [HBV], hepatitis C virus [HCV], and human immunodeficiency virus-HCV co-infection), autoimmune, hereditary, metabolic, and toxin-mediated liver disease. These diseases can lead to hepatocellular dysfunction, distortion of liver architecture, portal hypertension, and finally liver cirrhosis. Approximately 20%-30% of patients with chronic liver disease develop cirrhosis.1 In addition, the incidence of cirrhosis is increasing because of other causes like nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH) whi...

Liver Imaging Reporting and Data System: Review of Major Imaging Features
The American College of Radiology supported Liver Imaging Reporting And Data System (LI-RADS) is a comprehensive system for standardized interpretation and reporting of imaging examinations performed in patients at risk for hepatocellular carcinoma (HCC). The system is currently only applicable to patients at high risk for HCC. As defined in the American Association for the Study of Liver Diseases practice guidelines, these include patients with cirrhosis of any cause or chronic hepatitis B even in the absence of cirrhosis; they also include patients with current or prior HCC even in the absence of cirrhosis.

LI-RADS: Review of Major Imaging Features
The American College of Radiology (ACR)-supported Liver Imaging Reporting And Data System (LI-RADS) is a comprehensive system for standardized interpretation and reporting of imaging examinations performed in patients at risk for hepatocellular carcinoma (HCC). The system is currently only applicable to patients at high risk for HCC. As defined in the American Association for the Study of Liver Diseases (AASLD) practice guidelines, these include patients with cirrhosis of any cause or chronic hepatitis B even in the absence of cirrhosis; they also include patients with current or prior HCC even in the absence of cirrhosis....

Liver Imaging Reporting and Data System: Review of Ancillary Imaging Features
The American College of Radiology supported Liver Imaging Reporting And Data System (LI-RADS) is a comprehensive system for standardized interpretation and reporting of imaging examinations performed in patients at risk for hepatocellular carcinoma (HCC). As reviewed in the first article of a two-part series, LI-RADS uses 5 major imaging features to categorize LR-3, LR-4, and LR-5 observations. The major features are arterial phase enhancement, washout appearance, capsule appearance, diameter, and threshold growth. (Source: Seminars in Roentgenology)

Postloco-Regional Therapy Imaging of the Liver
Locoregional therapies play an increasingly important role in the management of liver tumors. Percutaneous image-guided tumor ablations are some of the most commonly performed locoregional therapies aimed at liver tumors. Tumor ablation techniques include radiofrequency ablation (RFA), microwave ablation (MWA), cryoablation, and irreversible electroporation (IRE). With any of the locoregional therapies, assessment of pretreatment and posttreatment changes is critical in assessing treatment response. (Source: Seminars in Roentgenology)
