It is useful in the diagnosis, staging, and treatment of cancer because it provides information that cannot be obtained by other techniques such as computed tomography and magnetic resonance imaging.

Arsenic 74 can be used as a positron emitter in PET - Positron Emission Tomography, the scope is to identify tumors.
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.
A positron is the antimatter counterpart to an electron, with the same mass but opposite charge. When a positron collides with an electron, they annihilate each other, producing energy in the form of gamma rays. Positrons are commonly used in medical imaging techniques such as positron emission tomography (PET).
It's radioactive. Cameras which sense the radioactivity can then produce an image of the area. Some are very highly detailed, such as a thallium scan of the heart; some are less so, such as gallium and indium scans. For plato, the answer is A

positron emission tomography (PET)
Positron Emission Tomography (PET) is a diagnostic procedure that uses positive radionuclides to reconstruct brain sections. By tracking the positron-emitting tracer molecules, PET can create detailed images of brain metabolism and function.
The technique is called positron emission tomography (PET). It involves injecting a radioactive form of glucose into the bloodstream, which is then taken up by active brain regions. The scanner detects the emitted positrons to create a map of brain activity.
Marie Curie and her husband Pierre Curie were pioneers in the field of nuclear medicine, their research laid the foundation for using radioactive isotopes to detect tumors. Nuclear medicine imaging techniques such as positron emission tomography (PET) and single photon emission computed tomography (SPECT) are widely used for tumor detection and diagnosis.
PET - Positron Emission Tomography
Positron emission tomography (PET) is used to diagnose a variety of medical conditions, including cancer, heart disease, and neurological disorders such as Alzheimer's disease and epilepsy. It helps visualize and evaluate the activity of organs and tissues in the body based on the detection of radioactive tracers.
