At Gleneagles Global Health City, we have specialists with expertise in nuclear medicine who provide the most accurate diagnosis for each patient’s condition. Additionally, we have diagnostic labs and advanced imaging equipment to reduce any chances of error in the detection and accelerate your journey to a better quality of life.
Pathophysiological information of organ systems of the body is derived through PET-CT scans. A PET-CT scan is a diagnostic imaging technique that combines the functional and anatomical information provided by positron emission tomography (PET) and computed tomography (CT), respectively.
PET-CT is a safe, non-invasive, and painless procedure routinely performed in exclusive hospitals world-wide. The overall time for the completion of the process is 3-4 hours, after which patients can return home and resume their routine lives.
Advantages of PET-CT
- Early-stage diagnosis of diseases and early recurrence of tumors
- Determine the extent, spread and severity of the disease in the body
- Helps in the selection of the most effective therapy based on the unique biologic characteristics of the tumor identified
- Gamma Camera
The gamma camera has long been the work-horse of nuclear medicine. The gamma camera studies allow us to reconstruct the physiological and pathological processes taking place in the body graphically by coupling radioactive isotopes to specific drugs, chemicals, and molecules and administering them. This imaging system is widely used in the evaluation of various organ systems, cancer evaluation and detection and localization of infections.
Furthermore, the superimposition of these images on anatomical images from a CT-scanner enables better localization of these processes. This is a hybrid form of imaging and is known as SPECT-CT.
- Targeted Radionuclide Therapy
Targeted radionuclide therapy involves a radioactive drug called a radiopharmaceutical that targets cancer cells. Radiopharmaceuticals typically consist of a radioactive atom (also known as a radionuclide) incorporated with a cell-targeting molecule that finds and kills cancerous cells.
When the radiopharmaceutical is injected into the patient’s bloodstream, it travels to and delivers radiation directly to or near disease sites. This treatment is known as ‘targeted’ radionuclide therapy because it damages cancerous cells, but at the same time, limits radiation exposure to healthy tissue. Hence, this type of therapy offers personalized treatment of cancer because it can be altered to the molecular properties of a specific tumor.
