What is Nuclear medicine?

Nuclear medicine is actually the science of collecting diagnostic information in a wide range of diseases, using compounds labeled with radionuclides.

Definition

To put it simply

radionuclides (i.e. the nuclei of the radioactive elements) enter the body systems and show how they function and metabolize. Most of the time these radionuclides enter the body by binding to a drug (which is specific to the function of a particular organ). They can be used to diagnose medical conditions such as coronary heart disease, pulmonary embolism, renal system dysfunctions, thyroid system dysfunctions, thyroid cancer, bone problems and bone metastases, inflammation, cancer, cerebrospinal system disorders, etc.

In nuclear medicine scans, after radionuclides enter the patient’s body, SPECT and PET devices are used to image the location of radionuclides in various organs, and even to check their displacement over time.

Using SPECT machines is known as the most common imaging technique in nuclear medicine.
