The radioactive substance commonly injected into the blood for medical imaging is a radiotracer, such as Technetium-99m. It is used in various imaging techniques, including positron emission tomography (PET) and single-photon emission computed tomography (SPECT), to help visualize internal organs and tissues. These radiotracers emit gamma rays, which can be detected by imaging equipment to assess physiological functions and detect diseases.

What is thyroid nuclear scan?
A thyroid nuclear medicine scan is a diagnostic procedure to evaluate the thyroid gland, which is located in the front of the neck and controls the body's metabolism. A radioactive substance that concentrates in the thyroid is taken orally or injected into a vein (intravenously), or both. A special camera is used to take an image of the distribution of the radioactive substance in and around the thyroid gland. This is interpreted to evaluate thyroid function and to diagnose abnormalities. i hope that this answer helped you..!
What is a radioactive tracer and 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.
Radioactive material is injected or inhaled and images are recorded?
"Lung Scan V/Q"ventilation perfusion scan radioactive test of lung ventilation and blood perfusion throughout the lung capillaries (Lung Scan)
Can neptunium be injected into the body?
No, neptunium is radioactive and dangerous !
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
How are tacers used to help with medical diagnosis?
A radioactive isotope which, when attached to a chemically similar substance or injected into a biological or physical system, can be traced by radiation detection devices, permitting determination of the distribution or location of the substance to which it is attached. Also known as radiotracer.
Is a procedure in which a radioactive substance is placed within the body to enable visualization of a bone via the image produced by the emission of radioactive particles?
The procedure you are referring to is called a bone scan. Radioactive substances are injected into the body and accumulate in areas of high bone activity. This allows for the detection of abnormalities in the bones through the emission of radioactive particles and subsequent imaging.
How do they administer the dye in a thyroid nuclear medicine scan?
Most often, the patient is given the radioactive substance in the form of a tasteless liquid or capsule. It may be injected into a vein (intravenously) in some instances.
What test require injecting the patient with a radioactive substance?
One common test that requires injecting a patient with a radioactive substance is a positron emission tomography (PET) scan. During this procedure, a radioactive tracer is injected into the patient's body, which emits positrons that are detected by the scanner to create detailed images of metabolic activity in tissues and organs. This technique is often used in oncology, cardiology, and neurology to diagnose and monitor various conditions.
Is radioactive waste a pure substance or a mixture?
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
What radioactive substance was injected and took over the host cells?
The radioactive substance commonly associated with being injected and taking over host cells is a radiopharmaceutical, such as iodine-131. This isotope is often used in medical treatments, particularly for thyroid cancer, where it is absorbed by thyroid cells and emits radiation to destroy malignant tissues. The targeted nature of iodine-131 allows it to effectively concentrate in thyroid cells, facilitating therapeutic effects while minimizing damage to surrounding healthy tissues.
