Transabdominal ultrasound (US) is the first‐line imaging method used to diagnose pancreatic lesions, but contrast techniques are needed to differentiate among inflammatory and malignant lesions, as well as between pseudocysts and cystic tumors. Contrast‐enhanced (CE) ultrasonography has been proven to be a useful tool in this regard with performance similar to contrast‐enhanced computer tomography/magnetic resonance imaging (CT/MRI), being also safer and nonirradiant. According to the EFSUMB guidelines on the nonhepatic use of contrast‐enhanced ultrasound (CEUS), this method is useful to improve characterization of ductal adenocarcinoma; to differentiate between pseudocysts and cystic tumors; to differentiate vascular (solid) from avascular (liquid/necrotic) components of a lesion; to better define the dimensions and margins of a lesion, including its relationship with adjacent vessels; and to help the choice for a next imaging technique.

Harmful use of alcohol is associated with more than 200 diseases and types of injuries, the liver being one of the most important targets. Alcoholic liver disease (ALD) is the most frequent cause of severe chronic liver disease in Europe and worldwide. ALD can progress from alcoholic fatty liver to alcoholic steatohepatitis and alcoholic liver cirrhosis, the grade of fibrosis being the key prognostic factor for the severity of the diseases. This chapter will present the place of liver elastography in the noninvasive assessment of ALD. It will describe the data available in the literature regarding the different elastography techniques for liver stiffness assessment and also the potential of these techniques for screening ALD.
