Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders, and other abnormalities within the body. It’s also called functional imaging or bioimaging.
Because nuclear medicine procedures are able to pinpoint molecular activity within the body, they offer the potential to identify disease in its earliest stages as well as a patient’s immediate response to therapeutic interventions.

Why do we use Nuclear Scan?
Radionuclide procedures are available for almost all organ systems just like the different X-ray procedures. It is used in the evaluation of the Heart, Lung, Brain, Bone, Kidneys, Liver, etc.
Scans are designed to study various aspects like concentration, excretion, drainage, the flow of tracers in various organs or localize/ characterize the pathology.
Nuclear medicine imaging procedures are noninvasive and, with the exception of intravenous injections, are usually painless medical tests that help physicians diagnose and evaluate medical conditions. These imaging scans use radioactive materials called radiopharmaceuticals or radiotracers.
Depending on the type of nuclear medicine exam, the radiotracer is either injected into the body, swallowed, or inhaled as a gas and eventually accumulates in the organ or area of the body being examined. Radioactive emissions from the radiotracer are detected by a special camera or imaging device that produces pictures and provides molecular information.
Nuclear medicine also offers therapeutic procedures, such as radioactive iodine (I-131) therapy that use small amounts of radioactive material to treat cancer and other medical conditions affecting the thyroid gland, as well as treatments for other cancers and medical conditions.
I 131 MIBG therapy for neuroendocrine tumour
Bone pain palliation therapy with P 32, Sm 153, Sr 89 extra
Y90, Lu177 therapy (RIT) is done for lymphoma, neuroendocrine tumour, malignant carcinoid patients who do not respond to chemotherapy. Radio immunotherapy (RIT) is a personalized cancer treatment that combines radiation therapy with the targeting ability of immunotherapy, a treatment that mimics cellular activity in the body’s immune system.

What is PET-CT scan – GE?
Positron emission tomography (PET) (better known as PET-CT or PET/CT) is a medical imaging technique which uses small amounts of radioactive materials called radiotracers, a special camera and a computer to help evaluate your organ and tissue functions.
F-18-SODIUM FLUORIDE PET CT
It has gained popularity since its high sensitivity and specificity in differentiating benign from malignant lesions compared to Tc 99m – MDP bone scan.
