An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium , usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...
An upper gastrointestinal series is where a contrast medium, usually a radiocontrast agent such as barium sulfate barium salt mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are used to create radiographs of the regions of interest. The barium enhances the visibility of the relevant parts of the ...
Upper gastrointestinal series is the modality of choice for the evaluation of malrotation, as it will often show an abnormal position of the duodenum and duodeno-jejunal flexure (ligament of Treitz). In cases of malrotation complicated with volvulus, upper GI demonstrates a corkscrew appearance of the distal duodenum and jejunum.
In upper gastrointestinal series, the patient is instructed to take nothing by mouth, which means to abstain from eating and drinking , with the exception of drinking the barium sulfate suspension. The amount of time for this fast may vary, depending on the instructions given by the imaging facility and the area of the body to be scanned, but ...
Upper gastrointestinal series showing duodenojejuonostomy (white arrow). SMA syndrome can present in acute , acquired form (e.g. abruptly emerging within an inpatient stay following scoliosis surgery) as well as chronic form (i.e. developing throughout the course of a lifetime and advancing due to environmental triggers, life changes, or other ...

String sign, or gastrointestinal string sign (also called string sign of Kantour), is a medical term for a radiographic finding on an upper GI series, in which the patient is given a radio-opaque material, such as barium, to drink. X-rays are then taken of the patient's stomach and intestines.
There are diagnostic tools mostly involving the ingestion of barium sulphate to investigate disorders of the GI tract. [49] These are known as upper gastrointestinal series that enable imaging of the pharynx, larynx, oesophagus, stomach and small intestine [50] and lower gastrointestinal series for imaging of the colon.
