Nuclear Medicine, also known as functional or molecular imaging is a medical specialty that uses radioactive tracers (radiopharmaceuticals) to produce images of the body. These images demonstrate how your organs and tissues are functioning. These radiopharmaceuticals are given either intravenously or orally to diagnose and treat diseases in a safe, painless and cost effective way. Radiopharmaceuticals are unique in its ability to create functional images and are a very sensitive technique to detect abnormalities in organ function in terms of changes in physiology, biochemical processes and structure.
- PET CT
Positron emission tomography (PET) scans and it is one of the most advanced PET CT Scanners. PET scans use high-energy waves to produce three-dimensional images of areas inside the body. PET scans are generally performed on the whole body, and take about two hours. They provide information on the structure of internal organs and tissues, but unlike many other imaging tests, PET uniquely illuminates cancer by detecting the changes in biochemistry that occur prior to the formation of a tumour mass. This additional information can help find cancer sooner than with other imaging tests. It can also help measure the effects of cancer treatments.
- Gamma Camera
The gamma camera is a variable-angle diagnostic equipment. Its utilization involves injecting the patient with a pharmaceutical agent labeled with a small amount of radioactive material. The pharmaceutical is selected on the basis of the specific organ or tissue to be evaluated (such as heart, lungs, bone, kidney, liver, gall bladder function, thyroid and brain). The radiopharmaceutical isotopes used are very safe and procedures can be done easily as an outpatient. Nuclear imaging procedures are available in our state-of-the-art centre.
- Computed Tomography (CT)
CT scans use special X-rays to capture images of internal organs from several different angles. The images are sent to a computer, which generates cross-sections of body tissues and organs. CT scans can also be done very comfortably and quickly, often in as few as seven minutes. The final images show several types of tissue very clearly, including organs such as the liver, spleen, pancreas, kidneys, lungs, oesophagus, and stomach. CT imaging can uncover cancers in many parts of the body. Ultrasound and CT scans can also be used as guidance for biopsies.
