HIDA An early and widely used tracer; not used as much anymore, as others have progressively replaced it, [13] [6] but the term "HIDA scan" is sometimes used even when another tracer was involved, being treated as a catch-all synonym. technetium Tc 99m iprofenin paraisopropyl-iminodiacetic acid [10] PIPIDA technetium Tc 99m disofenin

A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay , it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from ...
The decay of Rubidium-82, which undergoes positron emission.. Rubidium-82 is produced by electron capture of its parent nucleus, strontium-82.The generator contains accelerator produced 82 Sr adsorbed on stannic oxide in a lead-shielded column and provides a means for obtaining sterile nonpyrogenic solutions of rubidium chloride (halide salt form capable of injection).
For a bone scan, the patient is injected with a small amount of radioactive material, such as 700–1,100 MBq (19–30 mCi) of 99m Tc-medronic acid and then scanned with a gamma camera. Medronic acid is a phosphate derivative which can exchange places with bone phosphate in regions of active bone growth, so anchoring the radioisotope to that ...

Iminodiacetic acid is the organic compound with the formula HN(CH 2 CO 2 H) 2, often abbreviated to IDA.A white solid, the compound is a dicarboxylic acid amine (the nitrogen atom forms a secondary amino group, not an imino group as the name suggests).
A flow tracer is any fluid property used to track the flow velocity (i.e., flow magnitude and direction) and circulation patterns. Tracers can be chemical properties, such as radioactive material , or chemical compounds, physical properties, such as density, temperature, salinity, or dyes, and can be natural or artificially induced.
