A gastric emptying study is a nuclear medicine study which provides an assessment of the stomach's ability to empty. It may be used if there are complications after gastric surgery, for gastric reflux , or suspected gastroparesis amongst other indications. [ 1 ]
A gastric emptying scintigraphy test involves eating a bland meal that contains a small amount of radioactive material. An external camera scans the abdomen to locate the radioactive material. The radiologist measures the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. The test can help confirm a diagnosis of dumping syndrome.
Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
A gastric emptying study is considered the gold standard to assess the gastric emptying rate. [49] A large number of studies have indicated that most cases of peptic ulcers, and gastritis, in humans are caused by Helicobacter pylori infection, and an association has been seen with the development of stomach cancer.

Residency trained nuclear medicine physicians have the most extensive training and highest level of certification, including all aspects of diagnosis and radionuclide therapy. However, current U.S. regulations do not prohibit other physicians from interpreting nuclear medicine studies and perform radionuclide therapy.
When enough full-thickness bites have been taken for a suture row, a cinch is passed through the scope over the suture. Typically, sutures are placed starting at the border of the antrum and gastric body at the incisura, then placed proximally up to the border of the gastric body and fundus. Each row of sutures can be a straight line or one of ...
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), [2] but is able to provide true 3D information. This information is typically ...
