Overview of Radiology Positron Emission Tomography Scan Treatment India

Positron Emission Tomography (PET) Scan is a type of imaging test which helps to diagnose different diseases occurring in the body. PET scan detects the abnormal activity in the body which occurs due to the presence of some disease. The PET scan involves the use of some radioactive substance which is injected into the blood vessel of the patient. This radioactive substance then circulates in the whole body and accumulates in the area where high activity of cells and tissue is present due to some disease. After the injection, PET scan is taken which shows the accumulation of radioactive substances in the specific area. In this way, PET scan finds out the area under disease and also the severity or extent of the disease. PET scan is usually used to find out the diseases that occur in the brain and heart. It also provides information about the cancer and its stage. PET scan also helps to plan the treatment of an individual patient according to the level of severity of the disease. PET scan also has some of the risk factors that should be avoided in order to lower the chances of complications. The procedure of PET Scan usually takes 2 hours and it does not require any recovery after the procedure.

Types of Radiology Positron Emission Tomography Scan Treatment India

Some of the types of PET scan according to the areas of body are as follow:

  • FDG-PET Scan
  • Cardiac PET Scan
  • Brain PET Scan
  • Bone PET Scan
  • Gastrointestinal PET Scan
  • Thyroid PET Scan
  • Infection Imaging PET Scan
  • Whole-Body PET Scan


This is the most common type of PET scan. It uses a radioactive substance which is known as glucose tracer (FDG). This radioactive substance measures the activity in cells. It is widely used in detection of cancer and its stage.

Cardiac PET Scan

Cardiac PET scan is the diagnostic method in which the activity of the heart is examined and also the blood supply of the heart. It can provide information on the abnormal blood flow to the heart. 

Brain PET Scan

Brain PET scans use radioactive substances that highlight areas of the brain with abnormal activity. This method is widely used in the diagnosis of the conditions of the brain.

Bone PET Scan

The PET scan to diagnose the conditions of bone are also used in the diagnostic procedures by the health care professionals.

Gastrointestinal PET Scan

These scans can examine the conditions of the digestive system and also describe the level of severity of the disease.

Thyroid PET Scan

Thyroid PET scans help to examine thyroid gland to detect thyroid cancer by using radioactive substances.

Infection Imaging PET Scan

These scans can identify areas of infection by using radioactive substances that accumulate in infected tissues.

Whole-Body PET Scan

This scan covers the entire body and is often used in cancer staging to check for the spread of cancer to different organs and tissues.

Procedure of PET Scan

The general overview of the PET Scan procedure is described below:

Radioactive substance Injection: A small amount of a radioactive substance is injected into a vein in the arm of the patient. This substance is typically a type of sugar and different tissues in the body absorb it according to the activity of cells.

Scanning: The patient will be positioned on a flat table that slides into the PET scanner. The scanner detects the radioactive emissions from the radioactive substance within the body and creates images that show the distribution of that substance. Patients need to lie still during the scan which can take 30 minutes to two hours.

Image Interpretation: The collected data is processed by a computer to create detailed images of the internal structures of your body. Radiologists or nuclear medicine specialists analyze these images to identify any abnormal areas with high uptake of radioactive substances.

Results and Diagnosis: The doctor examines the results of PET scan and makes a diagnosis according to that. It can help diagnose conditions like cancer, evaluate the extent of disease, monitor treatment effectiveness, or assess other medical issues that usually depend on the purpose of the scan.

Risk Factors of PET Scan

Some of the risk factors that are associated with PET Scan are as follow:

Radiation Exposure

The radioactive substances used in the procedure of PET Scan can be harmful for some patients and may cause nausea, vomiting and fatigue.


Excess use of radiation can destroy normal cells both in male and female reproductive system and may lead to the problems of infertility.

General Side Effects

Some patients experience the symptoms of headache, abdominal pain, constipation or diarrhea but it may not present in all patients.

Kidney Disorders

Some patients may experience the symptoms of back pain due to the dysfunction of the kidney. This is most commonly present in patients with already existing kidney diseases.

Allergic Reactions

Some patients are allergic to radioactive substances used in the procedure. These patients experience the symptoms of skin rash and itching.

Irritation and Tiredness

Some patients show irritation and extreme tiredness after the procedure. These complications can affect the daily activities of patients.

Existing Medical Condition

PET scan procedure may cause some of the complications in patients with an already existing medical condition. These complications can vary according to the type of disease and the condition of each patient.

Decrease Blood Count

The radioactive substance can also affect the blood cells in the body and may cause bleeding, infection and decrease blood cells production.
