Which substance is administered in preparation for a nuclear scan?
A radioactive tracer, such as technetium-99m, is typically administered in preparation for a nuclear scan. This tracer is designed to accumulate in specific tissues or organs of interest, allowing for detailed imaging and evaluation of their functioning.
Which technique is also known as scintigram?
A scintigram is a diagnostic imaging technique that uses radioactive tracer particles to produce images of organs and tissues in the body. It is also known as a nuclear medicine scan.
What the meaning of radioactive?
Radioactive means that an atom is unstable and undergoes radioactive decay, emitting radiation in the form of particles or electromagnetic waves. This process can result in the release of energy and transformation of the atom into a different element.
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
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 radioactive tracer Give an example of how one might be used.?
A radioactive tracer is a radioactive atom inserted in a compound to see what happens to it in a reaction, usually in biotechnology. For example, to find out where carbon atoms go in photosynthesis, scientists can give the plants carbon dioxide with carbon-14 instead of carbon-12 and track the progress of the carbon-14.

How does radioactive tracer get into the body?
They dissolve it in a liquid and the patient drinks it
How much radioactive tracer is injected into the vein for a typical bone scan?
About 1 Mg.
Nuclear medicine uses these to image organs for diagnosis and treatment?
radioactive material called a tracer
Radioactive isotopes that can be followed through a chemical reaction or a industrial process is?
tracer
Would a substance with a one second life be effective as a radioactive tracer?
the dog ate the bacon
Would a substance with a one-second half-life be effective as a radioactive tracer?
the dog ate the bacon
What kind of tracer is used in a bone scan?
A radioactive tracer called technetium-99m is commonly used in bone scans. This tracer is injected into the bloodstream and accumulates in areas of the bones where there is increased activity, such as in cases of fractures, infections, or tumors.
A tracer is a radioactive element whose pathway through the steps of a chemical reaction can be followed?
Yes a tracer is a radioactive element whose pathway through the steps of a chemical reaction can be followed. It can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products.
How dangerous is technetium?
Technetium is not really dangerous. Since doctors will often use Technetium 99 as a radioactive tracer. It may be radioactive but its decay is slow and will produce a minute amount of gamma rays.
Four uses of radioactive isotopes are?
- energy source - radiation source - tracer - fuel for nuclear reactors - explosive for nuclear bombs
