AP supine radiograph can be performed as a standalone projection or as part of an acute abdominal series, depending on the clinical question posed, local protocol and the availability of other imaging modalities.
the patient is supine, lying on their back, either on the X-ray ...
The lateral decubitus abdominal radiograph is used to identify free intraperitoneal gas (pneumoperitoneum). It can be performed when the patient is unable to be transferred to, or other imaging modalities (e.g. CT) are not available. The most useful position for detecting free intraperitoneal ai...
The PA erect abdominal radiograph is often obtained in conjunction with the AP supine abdominal view in the acute abdominal series of radiographs. When used together it is a valuable projection in assessing air fluid levels, and free air in the abdominal cavity.
The erect abdominal radiograph h...
AP supine radiograph for neonates is a mobile examination performed on the neonatal unit. It can be taken as a standalone projection or as part of a series including a left lateral decubitus x-ray in cases of suspected perforation.
the patient is supine, lying on their back i...
Abdominal radiography can be useful in many settings. Before the advent of computed tomography (CT) imaging, it was a primary means of investigating gastrointestinal pathology and often allowed indirect evaluation of other abdominal viscera.
Although abdominal radiography has lower...
The acute abdominal series is a common set of abdominal radiographs obtained to evaluate bowel gas.
The acute series is used for a variety of indications including:
determine the amount of bowel gas, with possible bowel distention
assess air-fluid levels
This is a basic article for medical students and other non-radiologists
CT abdomen is an increasingly common investigation that is used to help make diagnoses of a broad range of pathologies. A CT abdomen in its simplest form is a CT from diaphragm to symphysis pubis performed 60 seconds after ...
CT polytrauma/multitrauma, also called trauma CT, whole body CT (WBCT) or panscan, is an increasingly used investigation in patients with multiple injuries sustained after significant trauma.
Clinical assessment and mechanism of injury may underestimate injury severity by 30% 8. There is some e...
This article lists examples of normal imaging of the gastrointestinal tract and surrounding structures, divided by modality.
example 1: abdominal film
example 2: erect and supine
example 3, example 4: paediatric
example 5: young adult male

Oral cholecystography was a procedure used to image the gallbladder, now largely superseded by ultrasound and MRCP. It was first described by Graham et. al in 1925, using sodium tetraiodophenolphthalein.
Although rarely performed now, more modern techniques used other cholegraphic agents such...
Peroral pneumocolon is a technique that can be used during a small bowel follow through (SBFT) to better visualize the ascending colon and terminal ileum.
The goal of a peroral pneumocolon is to create a double contrast study (oral contrast and gas) of the ascending colon and termina...
The Sitz marker study is an older technique to estimate colonic transit time.
In constipation it can help distinguish between slow colonic transit and a defecation disorder.
The patient ingests a number of radio-opaque markers (plastic rings containing radio-opaque mat...
