Reduction in patients length of stay in hospitals as a result of timely follow up of radiology studies

If you or a loved one is facing a cancer diagnosis, you may hear your doctor talk about a PET scan. A PET (positron emission tomography) scan is a type of imaging test that can reveal information about cancer, as well as other conditions such as heart disease and brain disorders.

A PET scan is an important tool that can provide valuable information about cancer, heart disease, and other conditions. By understanding what to expect before, during, and after the exam, you can feel more prepared and comfortable during the process. Remember to follow your doctor’s instructions carefully, and don’t hesitate to ask questions if you have any concerns. With the help of a PET scan, you and your doctor can make informed decisions about your health and treatment.

What is a PET Scan?

A PET scan uses a small amount of radioactive material, called a tracer, to help visualize the function of organs and tissues in the body. The tracer is injected into a vein, swallowed, or inhaled, and it travels to the areas of the body being studied. Once there, the tracer emits radiation that is picked up by the PET scanner, which creates 3D images of the body. PET scans are often combined with CT (computed tomography) scans to provide more detailed information about the body’s structure and function.

Who needs a PET Scan?

PET scans are commonly used to detect and monitor cancer, as well as evaluate the effectiveness of cancer treatment. They can also be used to diagnose and monitor heart disease, brain disorders, and other conditions. Your doctor may recommend a PET scan if they suspect you may have cancer or want more information about the extent of the disease. They may also use a PET scan to help guide treatment decisions, such as determining the best course of radiation therapy.

What to Expect?


Before your PET scan, you will need to follow some instructions to prepare. You will likely be asked to avoid food and drink for several hours before the exam, and you may need to limit your physical activity. You may also be asked to avoid certain medications and supplements leading up to the exam. Your doctor or imaging center will provide you with detailed instructions ahead of time.

During and After

During a PET scan, you will lie on a table that slides into the PET scanner. The scan typically takes 30-60 minutes, depending on the area of the body being studied. You may be asked to hold still and avoid talking or moving during the scan to ensure the images are clear. After the exam, you will be able to resume normal activities right away. Your doctor will review the images and provide you with the results, which may take a few days to prepare.
