What is PET-CT Scan?​

​

PET-CT scan, also known as positron emission tomography-computed tomography scan, is a medical imaging technique that combines two different types of scans to provide detailed information about the body’s organs and tissues. It is a non-invasive procedure that helps doctors diagnose and monitor various diseases, including cancer.

​

How does PET-CT Scan work?​

​

PET-CT scan works by using a small amount of radioactive material, called a radiotracer, which is injected into the patient’s body. This radiotracer emits positrons, which are detected by the PET scanner. The PET scanner then creates images that show the distribution of the radiotracer in the body. These images are then combined with the images from the CT scan, which provides detailed anatomical information.

​

What are the uses of PET-CT Scan?​

​

PET-CT scan is commonly used in oncology to detect and stage cancer, as well as to monitor the effectiveness of cancer treatment. It can also be used to evaluate certain neurological disorders, such as Alzheimer’s disease and epilepsy. Additionally, PET-CT scan can help identify areas of the heart that have been damaged by a heart attack or other cardiovascular conditions.

​

Is PET-CT Scan safe?​

​

PET-CT scan is generally considered safe, as the amount of radiation exposure from the procedure is minimal. However, as with any medical imaging test, there are some risks involved. The radiotracer used in the scan may cause an allergic reaction in some individuals. It is important to inform your doctor about any allergies or medical conditions you have before undergoing the scan.

​

How should I prepare for a PET-CT Scan?​

​

Prior to the PET-CT scan, you may be asked to follow certain instructions to ensure accurate results. These instructions may include avoiding food and drink for a few hours before the scan, as well as avoiding strenuous physical activity. You may also be asked to avoid certain medications or substances that could interfere with the scan. It is important to follow these instructions carefully to ensure a successful scan.

​

What can I expect during a PET-CT Scan?​

​

During the PET-CT scan, you will be asked to lie on a table that slides into the scanner. The scanner is shaped like a large donut and will move slowly around your body to capture images. You will need to remain still during the scan to ensure clear images. The scan itself is painless, but some individuals may experience claustrophobia or discomfort from lying still for an extended period of time.

​

How long does a PET-CT Scan take?​

​

The duration of a PET-CT scan can vary depending on the area of the body being scanned. Generally, the scan takes about 30-60 minutes to complete. However, additional time may be required for preparation and post-scan procedures.

​

Are there any side effects of PET-CT Scan?​

​

Most individuals do not experience any side effects from a PET-CT scan. However, some individuals may experience a mild allergic reaction to the radiotracer, such as itching or rash. In rare cases, more serious side effects, such as anaphylaxis, may occur. It is important to inform the medical staff if you experience any unusual symptoms during or after the scan.

​

Can anyone undergo a PET-CT Scan?​

​

Not everyone is a suitable candidate for a PET-CT scan. Pregnant women are generally advised to avoid the procedure, as the radiation could potentially harm the developing fetus. Individuals with certain medical conditions, such as kidney or liver problems, may also be advised against undergoing the scan. It is important to discuss your medical history with your doctor before scheduling a PET-CT scan.

​

How accurate is PET-CT Scan in detecting cancer?​

​

PET-CT scan is a highly sensitive imaging technique that can detect cancerous cells with great accuracy. It can help identify the location and extent of cancer, as well as determine if the cancer has spread to other parts of the body. However, it is important to note that PET-CT scan is not a definitive diagnostic tool. Further tests, such as biopsies, may be required to confirm a cancer diagnosis.

​

Can PET-CT Scan detect all types of cancer?​

​

PET-CT scan is effective in detecting many types of cancer, including lung, breast, colorectal, and lymphoma. However, its effectiveness may vary depending on the type and stage of cancer. Some types of cancer may not produce enough metabolic activity to be detected by the scan. It is important to consult with your doctor to determine if a PET-CT scan is the appropriate imaging test for your specific type of cancer.

​

What are the advantages of PET-CT Scan?​

​

PET-CT scan offers several advantages over other imaging techniques. It can provide detailed information about the metabolic activity of tissues, which can help differentiate between benign and malignant tumors. It can also help guide treatment decisions and monitor the response to therapy. Additionally, PET-CT scan can detect cancer at an earlier stage, when it is more treatable.

​

What are the limitations of PET-CT Scan?​

​

Although PET-CT scan is a powerful imaging tool, it does have some limitations. It may produce false-positive or false-negative results, leading to unnecessary procedures or missed diagnoses. Additionally, PET-CT scan is not suitable for individuals who are unable to lie still for an extended period of time, such as young children or individuals with severe claustrophobia. It is important to discuss the potential limitations of the scan with your doctor.

​

Does PET-CT Scan require a referral from a doctor?​

​

In most cases, a referral from a doctor is required to undergo a PET-CT scan. Your doctor will evaluate your medical history and symptoms to determine if a PET-CT scan is necessary. They will then provide you with a referral to a medical imaging center or hospital that offers PET-CT scanning services.

​

Are there any alternatives to PET-CT Scan?​

​

There are several alternative imaging techniques that can be used in place of a PET-CT scan, depending on the specific medical condition being evaluated. These alternatives include MRI (magnetic resonance imaging), CT (computed tomography), and ultrasound. Your doctor will determine the most appropriate imaging test based on your individual needs.

​

Is PET-CT Scan covered by insurance?​

​

PET-CT scan is generally covered by insurance for medically necessary purposes. However, coverage may vary depending on your insurance provider and specific policy. It is recommended to contact your insurance company prior to the scan to verify coverage and any associated costs.

​

Can I eat or drink before a PET-CT Scan?​

​

In most cases, you will be instructed to avoid eating or drinking for a certain period of time before the PET-CT scan.
