An x-ray of the abdomen is called as the abdominal x-ray. In this article we shall learn all about the procedure, reasons and possible risks of undergoing an abdominal x-ray.
Abdominal x-ray is also called as AXR or KUB. KUB stands for kidneys, ureter and bladder. AXR is done to take pictures of the organs in the abdomen. These organs include the liver, spleen, large intestine, stomach and the diaphragm. KUB is carried out to look for problems with the kidneys, ureter and bladder.
X-rays are actually radio waves that can pass through the body. When they reach a dense area, like bones, it creates a picture that is sent to the film. These dense areas appear white on the x-ray film. Less dense areas like muscles or organs appear gray as they block fewer of the x-rays. When the x-rays pass through without any obstruction, that area appears black.
