Nuclear Medicine is a branch of medicine that uses radioactive substances to diagnose various diseases and treat malignant & benign conditions. Nuclear medicine applications span a broad spectrum, ranging from risk assessment to diagnosis and treatment monitoring to radionuclide therapies. Modern nuclear medicine plays an essential role in achieving Personalized or Precision medicine, allowing both diagnosis and the selection of treatment tailored to the individual patient’s condition or predisposition towards disease.

Fundamental Advantages of Nuclear Medicine
Diagnostic Nuclear medicine involves using small yet traceable amounts of radioactive substances to image and/or measure an organ’s global or regional function. The extent to which a radiopharmaceutical is absorbed, or “taken up,” by a particular organ or tissue can be quantified to determine the level of function of the organ or tissue being studied. Among the different types of radionuclides available, the type of radionuclide used will depend on the kind of study and the body part being studied.
The radioactive tracer (radiopharmaceutical) is given to the patient by intravenous injection, orally, or by other routes depending on the organ and the function to be studied. The tracer substance uptake, turnover, and/or excretion is then analyzed with a gamma camera, positron emission tomography (PET) camera, or another instrument, such as a simple stationary radiation detector. The uptake of the tracer is generally a measure of the organ function or metabolism or the organ blood flow. The acquisition of the images will be followed by image interpretation and quantification.
