In children, abdominal x-ray is indicated in the acute setting: Suspected bowel obstruction or gastrointestinal perforation; Abdominal x-ray will demonstrate most cases of bowel obstruction, by showing dilated bowel loops. [1] Foreign body in the alimentary tract; can be identified if it is radiodense. [1] Suspected abdominal mass [1]
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
X-ray of abdomen of a person with gastric outlet obstruction taken while on their side. There is a prominent gastric air bubble, gastric air-fluid level, and a dilated stomach with particulate matter within it. Specialty: General surgery, gastroenterology
An x-ray image receptor, containing an anti-scatter grid and three AEC regions (represented by dark grey circles and square) These regions represent anatomical areas, e.g. lungs, spine. They can be selected individually, or all at once depending on the need. Automatic Exposure Control (AEC) is an X-ray exposure termination
For acute abdominal pain in adults, an abdominal X-ray has a low sensitivity and accuracy in general. Computed tomography provides an overall better surgical strategy planning, and possibly less unnecessary laparotomies. Abdominal X-ray is therefore not recommended for adults presenting in the emergency department with acute abdominal pain. [14]
