How it works?
We inject a tiny amount of radiotracer called fluorodeoxyglucose (FDG-18) into your body. This radioactive material emits signals depending on how much sugar your tissues are absorbing.
A PET scanner then detects these signals, measuring the activity of your cells. This helps us spot areas with increased or unusual activity, like where tumours may be developing.
At the same time, a CT scan uses X-rays to create detailed pictures of your body's structure, showing the size and location of organs and any potential issues. PET/CT scans typically have a lower radiation dose compared to conventional CT scans.
The PET/CT scan merges these details, giving us a complete picture of both metabolic activity and anatomical structures. This helps us understand your health more accurately.
b) PSMA PET Scan
Prostate-Specific Membrane Antigen PET (PSMA PET) scan, is an advanced medical imaging technique used in prostate cancer diagnosis and management. It is particularly valuable for detecting and staging prostate cancer, guiding treatment decisions, and monitoring the response to therapy with high precision.
How does it benefit prostate cancer management?
A PSMA PET scan enables timely action, making it an essential tool in the prostate cancer treatment process.
Detects prostate cancer at an earlier stage when it is most curable and treatable.
Pinpoints the exact location and extent of prostate cancer.
Provides detailed information for accurately staging the cancer.
Helps in personalizing treatment strategies based on the specific characteristics of the cancer.
Enables real-time monitoring of how well the cancer is responding to treatment.
Reduce the need for invasive procedures by providing comprehensive information through non-invasive imaging.
Contributes to better treatment outcomes through precise and targeted management.
Assists in more effective follow-up care by identifying any potential recurrence or spread of the cancer.
How it works?
A PSMA PET scan works by using a special radioactive substance that has a preference for prostate-specific membrane antigens (PSMA), found in higher amounts on prostate cancer cells.
You will receive an injection of a radioactive substance.
The injected radiotracer circulates in your body and is naturally absorbed by prostate cancer cells if they are present.
A PET scanner then captures images that highlight areas where the substance has accumulated, helping to pinpoint the location and extent of prostate cancer cells in your body.

How do doctors use radioactive drugs and imaging tools to identify diseases?
Radioactive drugs and imaging devices are commonly used in a medical technique called nuclear medicine to diagnose diseases. Radiotracers are special drugs containing a small amount of radioactive material. They are designed to emit gamma rays, which can be detected by imaging devices. Radiotracers can be administered in various ways, such as injection, ingestion, or inhalation, depending on the specific diagnostic procedure and the area of the body being examined. Once administered, the radiotracer circulates through the body and accumulates in the target organ or tissue. Imaging devices, such as gamma cameras or positron emission tomography (PET) scanners, are used to capture the gamma rays emitted by the radiotracer. As the radiotracer emits gamma rays, the imaging device creates detailed pictures or scans of the internal structures and functions of the body. Differences in the distribution or concentration of the radiotracer can indicate abnormalities, such as tumours, inflammation, or other diseases, helping in the diagnosis and staging of conditions.
Is a SPECT/Gamma Camera Scan safe, and does it involve radiation exposure?
While a SPECT/Gamma Camera Scan involves the use of a radioactive tracer, the amount of radiation exposure is typically considered safe for diagnostic purposes. The radioactive material used has a short half-life, meaning it loses its radioactivity quickly.
