Nuclear Medicine

Nuclear medicine is a medical specialty in which disease is diagnosed and treated by the application of radioactive substances. Nuclear medicine, is known exactly as, "radiology done inside out" or "endoradiology" because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays. Nuclear medicine is also known as physiological imaging modality; because it is differed from radiology (nuclear medicine is not emphasis on imaging anatomy). Single photon emission computed tomography (SPECT) and positron emission tomography (PET) scans are the two most collective imaging modalities in nuclear medicine.
