Beschreibungen/Notizen

• Abdominal radiographs often play an important role in the evaluation of patients with abdominal pain or distension or clinical signs of an acute abdomen. This chapter aims to review radiographic findings such as bowel dilation, pneumoperitoneum, and pneumatosis, and to discuss their significance. However, computed tomography and magnetic resonance imaging are recognized as more sensitive techniques than abdominal radiography for diagnosing a host of conditions in patients with acute abdominal symptoms. Contrast studies of the gastrointestinal tract can be performed using single‐ or double‐contrast techniques. Single‐contrast studies entail filling the lumen with a relatively low‐density barium suspension and evaluating for contour abnormalities or filling defects in the barium pool, whereas double‐contrast studies utilize a smaller amount of high‐density barium and gas to evaluate the en face appearance of the mucosal surface.
