FAQs about Oncology PET Scan in Chandigarh CHD
What is an oncology PET scan?
An oncology PET scan is a diagnostic imaging test that utilizes positron emission tomography (PET) to visualize metabolic processes in the body. It is particularly useful in oncology for detecting cancer, evaluating the effectiveness of treatment, and determining the stage of the disease. By injecting a small amount of radioactive glucose (FDG), the PET scan can highlight areas of high metabolic activity, which often correspond to cancerous tumors.
Why would a doctor recommend a PET scan?
A doctor may recommend a PET scan for several reasons, including to help diagnose cancer, assess how far cancer has spread in the body, evaluate the effectiveness of ongoing treatment, and check for recurrence after treatment. PET scans can provide information that other imaging studies, like CT or MRI scans, might not be able to offer, making it a valuable tool in comprehensive cancer care.
What should I expect during a PET scan?
During a PET scan, you will first receive an injection of a radioactive tracer. After a short waiting period, where the tracer circulates in your body, you will lie on a table that slides into the PET scanner. The procedure is painless and typically lasts about 30 to 60 minutes. You must remain still during imaging to ensure high-quality images. The technician will be in contact with you throughout the process.
How should I prepare for an oncology PET scan?
Preparation for an oncology PET scan often involves fasting for a few hours prior to the test to ensure accurate results. Your doctor will provide specific instructions based on your health condition and the type of cancer you are being diagnosed or treated for. It's vital to inform your healthcare provider of any medications you are taking or if you have any allergies.
Are there any risks associated with PET scans?
While PET scans are generally safe, they involve exposure to a small amount of radiation from the radioactive tracer. Your healthcare provider will weigh the risks and benefits before recommending the scan. It is particularly important to discuss any concerns if you are pregnant or breastfeeding.
