   The clinical area where radioisotopes are used for the diagnosis and treatment is called nuclear medicine. Nuclear medicine can be divided into the following subareas:

   1.  An in vitro test where various blood components are analyzed using radioisotopes following the blood sampling,
   2.  An in vivo test where a diagnosis is made by counting γ- or Y-rays emitted from the radioisotope-labeled drugs or obtaining the images immediately or after a certain amount of time following the infusion of drugs labeled with radioisotopes according to the therapeutic purpose,
   3.  The therapeutic area where the radioisotope is used for cancer treatment because the energy generated from the radioisotopes are emitted from the intracellular areas including cancer but their permeability is very negligible,
   4.  The physical and mechanic areas where the radioisotopes are counted, the images are generated and the effect of isotopes on human body is examined and
   5.  The chemical area where the radioactive drugs are developed for the purpose of diagnosis and treatment.

   As shown above, nuclear medicine is a clinical area which is synthetically formed based on various areas such as physics, chemistry, engineering, computer science, statistic, physiology, anatomy and medicine. In particular, it is a clinical area where an emphasis of the importance of physics is placed.

   Besides, depending on whether the radioisotopes emitting single photon or those emitting positron are used to obtain the images, the imaging system can be different. The former and the latter are called single photon emission computed tomography (SPECT) and positron emission tomography (PET), respectively.
