positron emission tomography
positron-emission tomography(PET Scan)
The imaging system that combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas is call PET or positron emission tomography. These types of scans are most commonly used check for brain function, poor blood flow and cancer.
positron-emission tomography(PET Scan)
Tracers can be located inside the human body using imaging techniques such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT). These techniques detect the signals emitted by tracers as they move through the body, allowing for visualization of their distribution and accumulation in different tissues or organs.
Single Photon Emission Computed Tomography (SPECT)Single Photon Emission Computed Tomography
A physiological distribution tracer is a substance used in medical imaging and research to track the distribution and movement of fluids or compounds within biological systems. These tracers can be radioactive isotopes, fluorescent dyes, or other labeled molecules that can be detected using various imaging techniques. By observing how these tracers distribute in the body, researchers can gain insights into physiological processes, organ function, and disease states. They are commonly used in techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT).

Positron-emission tomography (PET) forms images of body tissues using radioactive tracers that emit positrons. This imaging technique is used to detect functional processes in the body, such as metabolism or blood flow, and is commonly used in medical diagnosis and research.
Arsenic 74 can be used as a positron emitter in PET - Positron Emission Tomography, the scope is to identify tumors.
Tracer: A radioactive isotope that can be followed through the steps of a chemical reaction or industrial process.Two example of Tracers:1. tracers are used in finding weak spots in metal pipes and especially in oil pipes.2. Tracers injected into the body travel to organs and other structures where the chemical is normally used. this detects radiation.
Medical technologies like PET (positron emission tomography) rely on the physics of elementary particles to visualize and track the behavior of positrons emitted by radioactive tracers in the body. Other examples include proton therapy for cancer treatment, which uses proton particles to target tumors with precision, and PET-MRI scanners that combine PET imaging with magnetic resonance imaging for better diagnostic capabilities.
A radioisotope can be used as a tracer in the human body because tracers are used in the imaging the body's organs and tissues.
