Positron emission tomography (PET) scan is a type of nuclear medicine imaging test that uses a radioactive substance called a tracer to look for disease in the body.
It is commonly used in cancer imaging, metabolic scans, tumor detection, and functional imaging.
During a PET scan, the tracer is injected into the body and travels through the bloodstream to areas of the body where there is increased metabolic activity.
PET scan is a non-invasive procedure that provides detailed images of the body's internal structures and functions. It can help doctors diagnose and monitor a variety of conditions, including cancer, heart disease, brain disorders, and infections.
PET scan is particularly useful in detecting cancerous tumors, evaluating organ function, and assessing the effectiveness of treatments.
Some examples of PET scan applications include:
The primary purpose of performing a PET scan test is to obtain detailed images of the body's internal structures and functions to aid in the diagnosis and monitoring of various medical conditions.
Benefits of PET scan:
Scenarios where PET scan is useful:
The cost of PET scan tests in India can vary depending on several factors, including the location of the imaging center, the type of scan needed, and any additional services required.
On average, the cost of a PET scan in India ranges from Rs. 15,000 to Rs. 40,000.
It is essential to consult with your healthcare provider or the imaging center to get an accurate estimate of the cost of a PET scan test in India.
Comparing prices from different facilities and exploring insurance coverage options can help you manage the financial aspects of undergoing a PET scan.
The normal range of PET scan values can vary depending on the specific tracer used, the imaging protocol, and the area of the body being examined.
Generally, a PET scan result is considered normal when the tracer uptake is within a certain range of standardized uptake values (SUVs).

A PET scan is a type of imaging test that uses a radioactive substance to create detailed pictures of the inside of the body to help diagnose conditions like cancer, heart disease, and brain disorders.
High PET scan levels can indicate increased metabolic activity in the body, which may be a sign of various conditions, including cancer, infection, inflammation, or trauma.
Low PET scan levels indicate decreased metabolic activity in the body, which can be a normal finding or a sign of underlying health conditions.
A PET scan uses a small amount of radioactive material to show how your tissues and organs are working. The scan detects changes in cellular activity and metabolism to help diagnose conditions like cancer, heart disease, and brain disorders.
A PET scan can detect conditions like cancer, heart disease, and brain disorders by showing how your tissues and organs are functioning.
A PET scan shows how your tissues and organs are functioning, while an MRI and CT scan provide detailed images of your body's structures.
A PET scan is generally safe for most patients, but it may not be suitable for pregnant women or individuals with certain medical conditions. It's important to discuss any concerns with your healthcare provider before undergoing the procedure.
Before a PET scan, you may be asked to fast for a few hours to ensure accurate results. You should also inform your doctor about any medications you are taking, as they may affect the scan.
A PET scan typically takes about 30 minutes to 2 hours to complete, depending on the area being scanned and the specific protocol used by the imaging center.
Yes, a PET scan can detect cancer by showing areas in the body where cells are more active, such as cancer cells.
The risks associated with a PET scan are minimal. The most common risk is an allergic reaction to the radioactive tracer, which is rare.
PET scans are very accurate in diagnosing heart disease by showing how well blood is flowing through the heart muscle and identifying areas with poor blood flow or damage.
