Figure 1. Radioisotope scan to detect tumors. Technetium-99m is perhaps the most widely used radioisotope in diagnosis and treatment (the “m” stands for metastable). This isotope decays to Tc-99 and a gamma emission of low intensity, making the radiation damage fairly negligible. The half-life is about six hours, so it will remain in the ...

Medical tracers Radioactive isotopes and radioactively labelled molecules are used as tracers to identify abnormal bodily processes. This is possible because some elements tend to concentrate (in compound form) in certain parts of the body – iodine in the thyroid, phosphorus in the bones and potassium in the muscles.

Radioisotope gastric-emptying scan. During this test, the patient eats food containing a radioisotope, which is a slightly radioactive substance that will show up on a scan. The dosage of radiation from the radioisotope is very small and not harmful, but allows the radiologist to see the food in the stomach and how quickly it leaves the stomach, while the patient lies under a …

The trick is that the phosphorous source is made up of the radioactive isotope phosphorus-32. Now we let the cells grow for a while. Then we collect the cells, break them open and separate and...

8.1.1. Single photon emission computed tomography. In medicine, imaging the way in which a biologically interesting molecular species, labelled with a radioactive tracer, distributes through the human body provides one of the most powerful ways of studying normal physiology and identifying pathologies. Since Anger first invented the gamma ...

The gamma camera can show the part of the digestive tract where the radioactive-labeled cells are leaking out of the intestine, suggesting the location of the bleeding. This scan is useful mainly for people who have brisk bleeding in the digestive tract and who are not good candidates for endoscopy Endoscopy Endoscopy is an examination of internal structures using a flexible …
The Use of Radioactive Tracers in Biology and Medicine
https://pubs.rsna.org/doi/10.1148/39.5.541
Abstract. A very large share of investigative work in the biological sciences has been devoted to the study of the metabolism of organisms ranging in complexity from bacteria to man and embracing the more important members of the plant and animal kingdoms. Until the discovery of artificial radioactivity by Curie and Joliot in 1934 (1), the only ...
Gastric Emptying Study: Test Prep, Purpose, Results
https://www.verywellhealth.com/gastric-emptying-scan-procedure-4587997
It is also called a gastric emptying study or gastric emptying scintigraphy. The test is used to diagnose digestive conditions. A gastric emptying study is a nuclear medicine test, meaning it uses small amounts of radiation. It is usually done in the Nuclear Medicine department of your hospital as an inpatient or outpatient test.
Imaging Tests to help Diagnose Digestive Problems

Upper GI tests use X-rays to examine the esophagus, stomach, and first part of the small intestine (the duodenum). For these tests, you need to drink a chalky liquid called barium. As the barium ...
