The Molecular Imaging Centre has at its disposal a latest generation PET / CT Scanner and two Gamma Cameras, one with SPECT/CT capabilities.
What is Nuclear Medicine?
Nuclear Medicine imaging is a modality that investigates physiological processes within the body to diagnose and treat a variety of diseases. In a nuclear medicine test, small amounts of radioactive materials are introduced into the body by injection, swallowing, or inhalation. These tracers are absorbed by specific organs, bones, or tissues and emit gamma rays. These rays are detected by the gamma cameras and precise images are formed of the radiopharmaceutical distribution within the body.
Nuclear medicine imaging is unique and provides many advantages over other methods of imaging. It provides doctors with information about both structure and function. It is a way to gather medical information that would otherwise be unavailable, require surgery, or necessitate more expensive diagnostic tests. Nuclear medicine imaging procedures often identify abnormalities very early in the progress of a disease - long before many medical problems are apparent on other diagnostic tests.
Nuclear medicine tests are safe and generally painless. The amount of radiopharmaceutical used is carefully selected to provide the least amount of radiation exposure to the patient and ensure an accurate test.
PET/CT: What is it?
One of the most important applications of PET is in oncology, where whole body imaging is used effectively to identify tumours at their source and scan for metastatic spread of the disease. PET imaging is playing an increasingly significant role in radiation therapy, particularly for cancer diagnosis and staging, and also as an aid in target delineation for treatment planning - ideally using a single PET/CT scan for both the staging and planning roles.
Our PET/CT also is able to perform Diagnostic CT at the same patient visit.
PET/CT scans are performed to:
- Detect cancer
- Determine whether a cancer has spread in the body
- Assess the effectiveness of a treatment plan, such as cancer therapy
- Determine if a cancer has returned after treatment
- Evaluate brain abnormalities, such as tumours, memory disorders and seizures
