X-Ray Abdomen (Erect)
A focused scan for Bowel gas, Obstruction, Calcifications.
Overview
Examines Bowel gas, Obstruction, Calcifications. Performed at an NABL-accredited Meridian Health centre with a same-day report and a free doctor review.

What this scan measures
A plain film of the abdomen taken standing (erect), showing the pattern and distribution of bowel gas, any air-fluid levels, free gas under the diaphragm, calcifications, and the outlines of the liver, kidneys and psoas muscles.
It is an emergency-department test more than a routine one. It is ordered for acute abdominal pain and distension to look for intestinal obstruction, for suspected perforation, for a swallowed foreign body, and to check the position of a tube or device.
Symptoms that lead to this scan
- Severe abdominal pain with distension
- Persistent vomiting with absolute constipation
- Suspected swallowed foreign body
- Sudden severe abdominal pain with rigidity
- Checking the position of a nasogastric tube or stent
Understanding your results
Dilated bowel loops with multiple air-fluid levels form the classical pattern of intestinal obstruction, and free gas under the diaphragm suggests a perforated hollow organ — a surgical emergency. Both are patterns rather than diagnoses, and both are usually confirmed on CT, which is far more sensitive. A normal abdominal film is common in serious abdominal disease and never excludes it: if the pain is severe, the clinical assessment outranks the film.
Why the preparation matters
No preparation, and none is possible in the acute setting. The 'erect' part matters: you must stand or sit upright for several minutes before the exposure so that free gas can rise under the diaphragm and fluid levels can form. If you cannot stand, a left lateral decubitus film is taken instead for the same reason. Empty your bladder and remove metal from the waist.
X-Ray — safety and who should not be scanned
Full X-Ray guideThis is a low-dose ionising radiation test. Published reference figures put a chest X-ray at roughly the natural background radiation an average person absorbs over about ten days — less than a long-haul flight adds. Views through thicker tissue, such as the abdomen or lumbar spine, carry a meaningfully higher dose, which is why they are ordered more selectively. Modern digital detectors need far less radiation than the film systems they replaced, and the beam is collimated to the area being examined.
- Pregnancy, or any chance of it
- Tell the radiographer before the exposure, not after. X-rays of the chest or a limb deliver very little to the uterus and can often proceed with shielding when clinically necessary, but abdominal and pelvic views are usually deferred or replaced by ultrasound. The decision is made deliberately, by a doctor, in every case.
- Children and repeated imaging
- Children are more radiosensitive and have more years ahead in which an effect could appear, so paediatric exposures use reduced settings and every repeat is justified individually. If you have had several X-rays recently, say so — prior images can often be reused instead.
- Inability to hold the position or the breath
- Movement blurs the image and usually means the exposure has to be repeated, doubling the dose for no benefit. Tell the radiographer if pain, breathlessness or unsteadiness will make the position difficult; the view can almost always be adapted or supported.
- Metal and dense objects in the field
- Jewellery, coins, hairpins, bra underwires, belt buckles, dentures and some clothing prints appear as solid white shadows that can hide the anatomy underneath. They are removed before the exposure rather than worked around.
Who should consider this scan
- Anyone with acute abdominal pain and distension
- People with suspected bowel obstruction
- Patients with a suspected perforation
- Anyone who has swallowed a foreign body
- Patients needing tube or device position confirmed
