Nuclear Medicine

Overview

The Department of Nuclear Medicine at Sir H. N. Reliance Foundation Hospital offers advanced diagnostic and therapeutic services through state-of-the-art molecular imaging technologies. Focusing on precision and personalised care, we provide a full spectrum of services, including Diagnostic Nuclear Imaging and Targeted Radionuclide Therapies.  

While radiological scans show the structure of organs, nuclear medicine allows us to visualise how organs and tissues function in real-time. Our specialists can detect subtle molecular changes, such as abnormal metabolism, blood flow, or cancerous activity, using PET-CT and Gamma camera scans before structural changes appear. 

Our experienced nuclear medicine specialists use these insights to diagnose and treat precisely. The department also has cutting-edge imaging systems that offer high resolution and sensitivity. Designed with patient comfort in mind, our facilities follow an efficient, patient-friendly workflow to make every visit smooth and reassuring for our patients.

FAQs

Nuclear medicine is a medical speciality that uses radioactive medicines to assess bodily functions and to diagnose and treat diseases.  

Radiopharmaceuticals include special medications used in nuclear medicine to diagnose or treat various medical conditions. These medications contain small amounts of radioactive material, which allows doctors to take images of organs or target specific cells for treatment. 

Radiopharmaceuticals play a vital role in modern healthcare because they: 

  • Help diagnose diseases like cancer, heart conditions, and bone disorders.
  • Allow doctors to monitor the function of organs such as the heart, kidneys, and thyroid.
  • Assist in detecting tumours and infections at an early stage.
  • Treat certain diseases, such as thyroid cancer, neuroendocrine tumours, prostate cancers or bone pain due to cancer. 

Depending on the procedure, radiopharmaceuticals are administered either by injection, swallowing, or inhalation. The radioactive material travels through the body to the targeted organ or tissue.  

For diagnostic purposes, a special camera (Gamma camera or SPECT-CT scanner or PET-CT scanner) captures images of the organ as the radiopharmaceutical medication moves through the body. These images help doctors detect abnormalities or diseases.  

For treatment, the radiopharmaceutical delivers radiation directly to the targeted cells (such as cancer cells), helping to shrink or destroy them. 

  • Before the Procedure: Depending on the procedure, you may be asked to fast or avoid certain medications, depending on the type of scan or treatment. Always communicate with the Nuclear Medicine Department and your doctor for these instructions.
  • After the Procedure: You can usually return to normal activities right after the procedure. Drinking extra fluids helps your body eliminate the radioactive material faster.  
    In some procedures, you may have to avoid contact with family members, children, pregnant women and the general public. See specific procedure descriptions for details.

The radiation from radiopharmaceuticals is typically low and only affects the specific area being studied or treated, minimising exposure to other parts of the body. 

Radiopharmaceuticals are carefully regulated and used in very small, controlled amounts, making them safe for medical use. The body typically eliminates the radioactive material through urine or stool within a few hours or days after the procedure (depending on the type of procedure). The benefits of accurate diagnosis and targeted treatment usually outweigh the minimal risks associated with radiation exposure. 

Most patients do not experience side effects. Occasionally, some people may experience mild discomfort at the injection site. Allergic reactions are rare. 

For therapeutic nuclear medicine, your doctor will discuss potential side effects, which may vary based on the specific treatment. 

 

Yes, nuclear medicine is used safely for children. Paediatric doses are carefully calculated to minimise radiation exposure while still obtaining useful diagnostic or therapeutic results.
