Nuclear Medicine, a Super Speciality

What is Nuclear Medicine?

Nuclear medicine is a medical speciality that utilizes radioisotopes for the purpose of diagnosis and treatment. It is considered as a branch of radiology. Radioisotopes are nothing but simple substances like iodine, fluorine (which are normally present in the human body) which after some physicochemical modification can be applied for medicinal use. This speciality has been in use for the management of common and rare medical conditions since 1950s. This is a relatively advanced and expensive technology. In the earlier times, the applications were limited, however with increase in new inventions and better understanding of the disease processes, nuclear medicine has now become an integral part of the routine investigations and management of many diseases.

What are the Components of Nuclear Medicine?

This speciality encompasses various imaging investigations like gamma imaging with SPECT (Single Photon Emission Computerized Tomography) and CT, hybrid PET (Positron Emission Tomography) and CT and therapeutic applications like treating thyroid diseases, better palliative therapy of some cancers, palliation of bone pain in cancer patients, joint problems etc.

Gamma imaging includes bone scan, renal scan, liver scan, cardiac scan etc.
