General protocol For all of the ultrasound (US) shear wave elastography (SWE) techniques (vibration controlled transient elastography [VCTE], point shear wave elastography [pSWE] and two-dimensional shear wave elastography [2D-SWE]), adherence to a strict protocol when assessing liver stiffness is required.…
Introduction to stiffness Liver diseases, such as nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH), alcoholic liver disease, viral hepatitis as well others, may be characterized by the accumulation of extracellular matrix material (collagen, fibronectin, proteoglycans, and glycosaminoglycans), fats and triglycerides,…
Introduction Chronic liver disease (CLD) is a substantial worldwide problem. Any disease that incites liver inflammation can lead to liver fibrosis, which can then progress to cirrhosis. The stage of liver fibrosis is important to determine prognosis, surveillance, progression, or…

Abdominal wall disorders are frequently encountered in clinical practice, and may be associated with significant morbidity. Most abdominal wall or groin hernias can be easily diagnosed by inspection and palpation. In these cases, radiologic examinations are useful for preoperative demonstration…
Primary Neoplasms Primary tumors arising from the peritoneum are rare and are usually of mesenchymal origin. DESMOID TUMORS These tumors are related to benign but locally aggressive fibroblast proliferation or fibromatosis. The morbidity associated with these tumors is related to…
Introduction Ascites is the pathologic accumulation of fluid in the peritoneal cavity. It is a common finding that can be associated with a large number of diseases. Imaging plays an important role in detecting and characterizing ascites. Although ascites may…
Traditionally, the abdominal cavity has been divided into a number of peritoneal, retroperitoneal, and extraperitoneal spaces. Although it is useful for learning abdominal anatomy and appreciating the confinement of disease in a particular space, this classic approach affords limited understanding…
Splenic Trauma The spleen is the most commonly injured organ in blunt abdominal trauma. , It receives 5% of the cardiac output, accounts for 25% of the total reticuloendothelial cell mass, and plays a major role in clearing the plasma…
Although it is affected by many diseases, the spleen is not considered a great challenge to the radiologist. In daily practice, the size and shape of the spleen typically are subjectively evaluated, and if there is no obvious splenomegaly or…
