Abdominal X-Ray (AXR) is a plain X-Ray of the abdomen. It may be taken with the patient in an upright position (erect), lying down flat (supine) or lying on the side (decubitus). It can also be fine tuned to focus on the kidney, ureter and bladder (KUB). It is important you inform your doctor if you are pregnant as there is a small risk to the foetus, particularly in early pregnancy.
How the Test is Performed
Abdominal X-Ray (AXR) is performed by a radiographer in an X-Ray room with the patient either sitting up, lying flat or lying on the side.
Medical Conditions and Symptoms
Abdominal X-Ray (AXR) is useful in investigating flank pain (to look for kidney stones) and may also delineate the size and shape of organs such as the liver, kidney or spleen. It can be used to investigate symptoms such as nausea, vomiting and constipation and to determine the cause of abdominal distension (small or large bowel obstruction is classically well visualised). It can also be used to determine the presence of free air (in conditions such as perforated duodenum secondary to an ulcer).
Test Results Explained
Abdominal X-Ray (AXR) can determine the presence obstruction (enlarged bowel with trapped air), perforation (free air outside of the bowel wall), organomegaly (increased solid organ size), and the presence of stones and constipation.
