About Us
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.
Our Facilities
Unlike other forms of imaging, a PET scan shows molecular activity and helps doctors identify diseases in the earliest stages. For this reason, a PET scan is a highly reliable tool for detecting disease processes. PET CT combines two different imaging technologies in a single scan.PET measures the body’s biological processes, and CT generates high-resolution cross-sectional images of the body’s anatomy. By combining both sets of information into a single three-dimensional hybrid image, metabolic processes are mapped accurately in all spatial dimensions.
Imaging with Gamma Camera involves preparing and injecting radiopharmaceuticals that specifically trace the function of the Organ of Interest. Radiopharmaceuticals are made in the well-equipped Hot Lab in the Department of Nuclear Medicine and Molecular Imaging. These specific radiopharmaceuticals are administered to patients, and images are acquired. Static, dynamic, and parametric images can be obtained under a Gamma Camera.
Myocardial Perfusion Scan visualizes the distribution of tracer uptake in the heart muscle, which reflects regional blood flow in different coronary artery territories. This can be performed with 201T1/ 99m Tc- Sestamibi / Tetrofosmin.
Rest Injection Scan indicates whether the heart muscle is viable or scarred due to prior attacks. Stress (Exercise/Pharmacological) Scan reveals inducible ischemic perfusion defect corresponding to significant coronary disease.

Nuclear medicine therapy or radionuclide therapy involves the administration into the body of radiopharmaceuticals, safe amounts of radioactive material used for both treatment purposes. Organ or tissue-specific molecules can be used safely to carry radioactive materials inside the human body to acquire more accurate images of tumors and to target and eliminate cancer cells more effectively. This method of combining therapeutic and diagnostic uses of radiopharmaceuticals is called theranostics.
