What technology would be used in conjunction with the radioactive tracer iodine 131?

When conducting a thyroid scan, the patient needs to be given a dose of radioactive iodine by either swallowing or intravenously. During the scan, a gamma scintillation camera takes pictures of the thyroid gland from 3 different angles. The camera detects gamma ray emissions from the decay of the radioactive iodine. Thus the technology of the camera and the computer that generates the image of the thyroid gland are technologies used in conjunction with I-131

An example of an Radioactive tracer?
iodine 123 for looking at kidney function. or Technicium 99 a gamma source. there are other beta sources used for leak finding in industrial pipes
A is a molecule into which a radioisotope has been incorporated?
tracer
Why it is important to use radioactive tracers with short half-life?
You want the tracer to have a short half-life so that its radioactive impact to the object you are examining (usually, some organ in the body) is minimized. The best known example of a tracer is technicium-99m, with a low energy gamma photopeak of 140.511 KeV and a half-life of only 6 hours. Since this is a meta-stable form of technicium-99, there is no beta or alpha emission, making this an ideal tracer.
What is a Radioactive tracer useful in?
A tracer, whether radioactive, or chemical, or a dye, should not interfere with the normal functioning of the system being studied. And should be observable.In studying the transport of CO2 in plants, we used to manufacture an isotope of carbon, 11C, which had a half life of about 20 minutes. (We had to be a bit nippy in its manufacture and use!) This then, as CO2, transported through the plant as if it were normal CO2, making sugars etc, and the clever guys followed its passage with appropriate radioactivity counters.Another use concerns breathing, in which the subject breathes a slightly radioactive gas, and its passage is followed by a complex set of detectors. It is quite something to see, on a screen, your lungs breathing in and out, and to observe a blank portion of them that is not, for no gas is reaching this region! I trust you never have to experience this procedure.[Another class of tracers is the radio opaque materials which are dense as seen by x-rays. These are often used to study the flow of blood through your body, to detect embolisms, and blockages in the veins etc.]
What is a positron emission tomography test?
This isn't really a question, but here we go... PET technology is used in PET scans in hospitals. It is the largest scale use of antimatter currently available, as the emitted positrons are in fact the anti-particles of electrons. Therefore used improperly it can be extremely dangerous as if a particle meets its antiparticle they will annihilate.

About 1 Mg.
What is the only difference between ELISA and RIA?
RIA measures scintillation due to decay of radioactive tracer. ELISA measures a color change due to an enzyme tracer.
