Abdominal ultrasound is one of the most popular imaging examinations. On the advantage side, this procedure can be performed quickly, is easily accessible, involves no exposure to radiation and is inexpensive. However, imaging quality depends on the conditions during an examination (e.g., presence of bowel gas, the patient’s obesity) and experience of the sonographist. Therefore, ultrasound is often of limited value for the detection and characterization of lesions in the abdominal cavity but may be the first step in the evaluation of potential malignant disease and can be used in follow-up imaging. This article discusses the role of ultrasound in oncology, especially for the diagnosis and further management of malignant and benign lesions of the liver, gallbladder and bile ducts.
