What is a PET scan? How does the
PET scan work?
Positron emission tomography (PET) scans detect early signs of cancer, heart disease and brain disorders. An injectable radioactive tracer detects diseased cells.
You receive an IV injection of a radiotracer that contains a safe amount of a radioactive drug. The most commonly used radiotracer is fluorodeoxyglucose (FDG).
A combination PET and CT scan produces 3D images for a more accurate diagnosis.
What aspects can be viewed
through PET Scan?
Doctors perform PET/CT scan be useful to view various aspects few of
them include:
Detect cancer and/or makea diagnosis.- Determine whether a cancer has spread in the body.
- Assess the effectiveness of treatment.
- Determine if a cancer has returned after treatment.
- Evaluate Prognosis
- Assess tissue metabolism and viability.
- Determine the effects of a heart attack myocardial infarction on areas of the heart.
- Identify areas of the heart muscle that would benefit from angioplasty or coronary artery bypass surgery (in combination with a myocardial perfusion scan).
- Evaluate brain abnormalities such as memory disorders like Alzheimer's disease, Parkinson's disease, Seizures and other central nervous system disorders.
- Map normal human brain and heart function.
How can PET scan be useful to
detect health problems?
PET CT scan procedure can be used to detect a variety of problems in the body. Normally the PET scan is
performed to analyze the condition of:
Cancer:
Cancer cells are rapidly growing abnormal cells which tend to have higher metabotism rate compared to normal cells. So to the high metabolic rate these cells release chemicals which appear as spots during the screening process. Accordingly your specialist may recommend cancer treatment to you.
PET scans can show the areas where the blood flow is affected. This is viewed as the healthy tissue with proper blood flow tends to absorb more tracer than the unhealthy or damaged tissues. Each level has a different color and range of brightness can help the doctor in deciding the severity of the disease and get a clear view of the treatment to be provided
Brain Defects:
Glucose is considered the main functioning factor of the brain.
The tracers introduced for the PET scan attach to the glucose components in the brain.
So the areas which utilize the highest level of glucose and the ones which utilize less can be easily detected through scanning.

Radiation OncologistWhat Out Patients Are Saying
My sister had a couple of seizures and was always in a confused state of mind. So we decided to go to Sri Ramakrishna hospital to understand the condition of her health. The specialists suggested we take a PET scan for a better picture, the oncologists there were so helpful and guided through the whole process. The process was also very quick and we also received the results in a couple of hours after the procedure

Frequently Asked Questions
PET scans involve radioactive tracers which can emit radiation though in smaller amounts. If you are pregnant or breastfeeding there are chances of the child being exposed to the radiation. Sri Ramakrishna hospital has one of the most sophisticated PET scan centres in Coimbatore.
Cancer cells are rapidly growing abnormal cells which have higher metabolic rate than other normal functioning cells. So the trace used in the PET scans get attached to the cells which have high metabolic rate and shows up as bright spots which can be helpful in detecting cancer cells.
A PET scan involves introduction of radioactive tracers into the body which can help identify the damaged or infected tissues. These tracers take about an hour to get absorbed into the body. After an hour the radiologist performs the scan where the affected tissues seem to appear as bright spots in the body.
The PET scan complete procedure takes about 2 hours and usually the results are directly sent to your specialist within 24 hours of the scan.
In case you are pregnant, notify your doctor, ensure you consume a lot of water, and also remember to ask your doctor if you need to avoid eating anything specific.
