Vedclass · Answer

(B) Positron emission tomography $(PET)$ is a nuclear medicine functional imaging technique.It is highly effective because it utilizes isotopes of basic body elements (such as $C^{11}$,$N^{13}$,$O^{15}$,and $F^{18}$) that have very short half-lives.These isotopes are incorporated into biologically active molecules (like glucose),allowing for the visualization of metabolic processes in real-time.The short half-life minimizes the radiation exposure to the patient,making it a safe and preferred diagnostic tool.

Positron emission tomography $(PET)$ is one of the best methods for functional imaging because
