Nuclear Medicine Therapy in India

Nuclear Medicine

Nuclear medicine is a branch of medicine that involves the diagnostic and therapeutic use of radioactive materials (radiopharmaceuticals). Nuclear medicine imaging is used to study the structure and function of internal organs and to assist in the early detection of anomalies or cancers. Certain types of cancer and disorders are also treated with this discipline of medicine. Nuclear medicine examinations are painless and safe. They make it possible to diagnose a wide range of ailments and diseases quickly and accurately.

Nuclear Medicine in Diagnostics

A small amount of radioactive materials is employed in diagnostic procedures to help in viewing the organs, allowing the doctor to discover and identify the abnormalities, size of any tumors, and other physiological or functional problems with the organ.

This approach can also be used to track the course of the disease and its response to treatment. The treatment involves injecting radiopharmaceutical substances into the patients and imaging with PET (Positron Emission Tomography) or SPECT (Single Photon Emission Computed Tomography) cameras. The emission spectra produced by the radiopharmaceutical substances utilized can be read using these approaches.

Most Common Nuclear Medicine Imaging Applications

Nuclear Medicine offers applications in a wide range of diseases, with a focus on Oncology, Cardiology, Nephrology, Orthopedics, Rheumatology, and Neuropsychiatry in particular.

Physicians employ nuclear medicine imaging procedures to visualize the function of an organ, tissue, bone, or system in the body.


  • Visualize heart blood flow and function (such as myocardial perfusion scan)
  • Detect coronary artery disease and the extent of coronary stenosis
  • Assess damage to the heart post a heart attack
  • Evaluate treatment options, such as a bypass heart surgery and angioplasty
  • Evaluate the results of revascularization (blood flow restoration) procedures
  • Detect heart transplant rejection
  • Evaluate heart function before and after chemotherapy (MUGA)


  • Scan lungs for respiratory and blood flow problems
  • Assess differential lung function for lung reduction or transplant surgery
  • Detect lung transplant rejection


  • Evaluate bones for fractures, infection and arthritis

  • Detect the early onset of neurological disorders, such as Alzheimer's disease
  • Assist in surgical planning and identify the areas of the brain that may be causing seizures
  • Evaluate for abnormalities in a chemical in the brain involved in controlling movement in patients with suspected Parkinson's disease or related movement disorders
  • Evaluation for suspected brain tumor recurrence, surgical or radiation planning or localization for biopsy


  • Stage of cancer by determining the presence of spread of cancer in various parts of the body
  • Localise sentinel lymph nodes before surgery in patients with breast cancer or skin & soft tissue tumours
  • Plan treatment
  • Evaluate response to therapy

  • Evaluate kidneys for infection versus scar


  • Identify inflammation or abnormal function of the gallbladder
  • Identify bleeding into the bowel
  • Assess post-operative complications of gallbladder surgery
  • Locate the presence of an infection
  • Measure thyroid function to detect an overactive or underactive thyroid
  • Help diagnose hyperthyroidism and blood cell disorders
  • Evaluate spinal fluid flow and potential fluid leaks

Nuclear Medicine in Therapeutics

Nuclear medicine can also be used to treat numerous types of disorders that involve a modest amount of radioactive material. Patients with Thyroid Cancers or an overactive thyroid gland, Neuroendocrine Tumors, Prostate Cancers, Lymphomas, and Liver Tumors are frequently provided nuclear medicine as a therapeutic option.

This targeted therapy strategy damages cancer cells with a little amount of radioactive material or radioisotope, known as Radiopharmaceutical. To deposit fatal radiation into the tumor, the radioactive chemical is conjugated with a tumor-targeting agent. It comes in the shape of a drink, an injection, or a capsule.

Most Popular Nuclear Medicine Therapies in India:

  • Alpha PSMA Therapy
  • Lu PSMA Therapy
  • Peptide Receptor Radionuclide Therapy (PRRT)
  • I-131 MIBG Therapy

How does Nuclear Medicine Therapy Works?

Nuclear Medicine Therapy is a relatively new specialty of medicine that combines precision therapeutic strategies with molecular imaging tools. It uses molecular diagnostic tools to diagnose the condition and then uses the same technology to give a radiation dose to the affected area (abnormal tissues).

It is based on the concept of "Theranostics," a ground-breaking field that focuses on giving each patient the correct medicine at the right time and in the right amount.

Iodine-131 therapy for an overactive thyroid gland and thyroid cancer, PRRT for neuroendocrine tumors, and PSMA therapy for prostate cancer are all examples of this method.

Radiation from radioactive material has a greater impact on cancer cells and other illness cells than on normal cells. The radiopharmaceutical chemical has the potential to destroy cancer cells or shrink tumors in the long run.

This is how it works:

A naturally occurring or man-made compound that emits radiation energy is known as radioactive material. The radioactive substance or radiopharmaceutical molecule can be utilized to kill cancer cells or slow the progression of the disease. The material can be solid, liquid, or gas, and it can be given to target cells in a variety of ways depending on the part of the body.

For example, radon is a gas that can be inhaled for therapy, but radioiodine comes in the shape of a capsule or liquid that must be eaten. Every radioisotope has a half-life that defines when it will no longer be radioactive.

Advantages of Nuclear Medicine:

  • Nuclear medicine methods provide details on both the function and anatomic structure of the body that are sometimes unavailable with other imaging procedures.
  • Nuclear Medicine has the ability to diagnose disease at an early stage, frequently before symptoms or anomalies are recognised by traditional diagnostic tests.
  • PET scans may obviate the need for surgical biopsy or determine the optimum biopsy location by determining whether lesions are likely benign or malignant.
  • PET CT guided biopsies aid in more accurate cancer diagnosis.

How is Nuclear Medicine Therapy given?

The patient is positioned on an examination table, and the dose of radiotracer is given intravenously, ingested, or inhaled as a gas, depending on the type of Nuclear Medicine Exam. The radiotracer can take anywhere from a few seconds to many days to move through the body and collect in the organ or location being investigated. As a result, imaging can be done right away, a few hours later, or even several days after the radioactive material has been received.

When it's time for imaging, the camera or scanner will capture a series of photos by rotating around the patient's body or staying in one position with the patient changing postures in between.

The patient is urged to remain immobile for short periods of time while the camera takes photographs. To capture the greatest quality photographs, the camera may come very close to the body in some circumstances. If a patient is claustrophobic, the technician should be informed before the examination begins.

Nuclear Medicine Procedures take a different amount of time depending on the type of exam. The scanning process can take anywhere from 20 minutes to several hours, and in rare situations, it may take many days.

  • Cancer is daunting. I was diagnosed with breast cancer and advised to travel immediately to India for the treatment. Found IndiCure online and traveled within 10 days. We were well received by Team IndiCure and got immediate treatment. I am very much humbled with the kindness of the doctors- each time we met they cleared all our doubts and were very helpful.

    After undergoing 6 cycles of chemotherapy and surgery, I am cancer free now and ready to travel back to my country.

    Thank you so much IndiCure for all the help.

    Treatment: Multiple Myeloma

  • I am highly indebted to the whole IndiCure team and Dr. Singh specifically for saving my life. The doctors in my home country Ghana had clearly stated that if I do not get operated for a brain tumor at the earliest, I would not live more than a month. But the promptness with which IndiCure team arranged things for me was something extraordinary. I am extremely satisfied with the whole experience and completely relieved of all my symptoms. Thanks a lot!

    Michelle Ramos,Ghana

Your team was instrumental in setting up my Dad with Dr. Babu and other healthcare teams. Your professionalism is exceptional. You responded to my all concerns within 24 hours; you reassured me everything would be okay when I needed it the most; you showed compassion that I've never seen before. Dr. Babu successfully operated on my Dad and we are so grateful for that. I would like to say a special thank you to Mr. Bachir, whom my dad now calls a friend. Mr. Bachir went above and beyond his job responsibilities and responded to the present every time my father needed him. I will recommend your services to friends and family every time I get the opportunity to do so. No amount of words can express my gratitude, so on behalf of my family, we would like to THANK YOU. Sincerely, a father's daughter.

Frequently Asked Questions

The majority of nuclear medicine imaging methods are non-invasive. With the exception of some scans that require an intravenous injection, these scans are normally painless. The radiopharmaceuticals or radiotracers employed in these scans build up in the area being investigated and generate energy in the form of gamma rays or positrons. A unique camera detects them and produces images as well as molecular information.

Doctors can superimpose nuclear medicine images with Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) images to create customized perspectives that provide more precise information and accurate diagnoses when needed.

Traditional Imaging Systems, such as CT (Computed Tomography) Scan, MRI (Magnetic Resonance Imaging) Scan, and others, show only the anatomy or structure of the tissue or organ being investigated, whereas Nuclear Imaging Techniques show the physiological function of the tissue or organ being investigated.

While a limited amount of radiation is utilized and it mostly helps the patient, it does not affect others. As a result, the patient will need to take some precautions to ensure that the radiation does not harm others.

However, It is critical that you inform your doctor and the nuclear medicine service team if you are pregnant, think you might be pregnant, or are breastfeeding before receiving the therapeutic dose. Many nuclear medicine procedures necessitate a pregnancy test within 24 hours of treatment for all women of childbearing age. After some types of therapy, the patient must ensure that she does not become pregnant for at least six months.

After nuclear medicine therapy, there may be some side effects, but they are usually small. Our Nuclear Medicine Specialist will go through all of the possible side effects and consequences in detail. The doctor will also discuss how you might minimize or eliminate negative effects.

The length of time spent in the hospital is determined on the type of nuclear medicine therapy used and the ailment being treated. The majority of therapies are offered as outpatient services, so you may not need to stay in the hospital. Certain types of therapy may necessitate a two- or three-day stay in the hospital. This is to ensure that the patient's radioactivity is reduced to a safe level before they leave the hospital.
