Final answer:
Nuclear medicine diagnostic applications, like PET scans, involve the use of radioisotopes and produce detailed images of body structures. Conditions for participation include understanding radiation exposure, shielding needs, dealing with high costs, equipment availability, and potential confinement during the imaging process.
Step-by-step explanation:
In nuclear medicine, diagnostic medical applications are a cornerstone, with the use of tools such as PET scans and isotopic studies. These procedures require the introduction of radioisotopes into the body, which emit radiation detectable by imaging equipment. The types of radiation can vary, measured in mrem or mSv units. The PET scan, or Positron Emission Tomography, is one such method that involves administering a radioactive isotope which, once metabolized by the body, emits gamma rays that are captured by the scanner to produce detailed images of the body's structure and function.
However, there are certain conditions that must be met for a patient to participate in such services. Patients should be informed of the potential release of radiation and the need for shielding from magnetic signals. There are also practical considerations, such as the high cost of the procedures, availability of equipment, and the fact that PET scans can only view metabolically active tissues. Additionally, some imaging procedures may require patients to remain confined within a metal tube for a duration, which can be challenging for some individuals.
