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?
One example of a radioactive tracer is technetium-99m, which is commonly used in medical imaging. It emits gamma radiation that can be detected by imaging equipment, allowing doctors to track its movement within the body to diagnose conditions such as heart disease or cancer.
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 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.

How can a radioactive tracer be used to locate tumors?
A radioactive tracer is a small amount of radioactive material that can be injected into the body, where it accumulates in specific tissues or organs. In the case of tumors, the tracer is often designed to target cancerous cells that have increased metabolic activity. When scanned with imaging techniques like PET (positron emission tomography), the tracer emits radiation that is detected, allowing doctors to visualize the location and size of the tumor. This method helps in diagnosing cancer and guiding treatment decisions.
How much radioactive tracer is injected into the vein for a typical bone scan?
About 1 Mg.
