What is a PET-CT Scan?
PET-CT Scan refers to Positron Emission Tomography - Computed Tomography Scan detects the starting signs of heart disease, brain disorder, and cancer. A small amount of injectable radioactive materials called radiotracers or radiopharmaceuticals detect diseased cells.
To check the symptoms of various diseases such as cancer, including breast cancer, lung cancer,
thyroid cancer, coronary artery disease,
heart attack, and other heart problems this PET-CT scan is used. Even brain disorders like brain tumours, epilepsy, dementia, and Alzheimer's disorder will be detected through this test.
Why do I need a PET-CT scan?
PET-CT scans are commonly used for various types of cancer. They are generally considered more accurate in diagnosing
cancer compared to PET or CT scans alone. PET-CT scans have several benefits, including:
- Helping to diagnose cancer.
- Determining the size of the cancer and whether it has spread (staging).
- Assisting in the decision-making process for surgery to remove the cancer.
- Guiding the selection of the most suitable treatment for cancer.
- Monitoring whether the cancer has returned.
- Planning radiotherapy treatment.
- Assessing the effectiveness of cancer treatment.
Following cancer treatment, a scan may reveal an area that appears to still contain cancer cells. However, this could be scar tissue remaining from the cancer that was eliminated by the treatment.
PET-CT Scan Types
PET-CT scans are tailored to specific needs and may vary based on the condition being evaluated. Some common types include:
- Whole-body PET-CT for cancer detection.
- Cardiac PET-CT for heart function analysis.
- Brain PET-CT for detecting neurological disorders.
PET-CT Scan Uses
A PET-CT scan is commonly used to check for:
- Various cancers, such as breast, lung, and thyroid cancer.
- Heart diseases, including coronary heart attacks.
- Brain disorders, such as brain tumors, dementia, and Alzheimer's disease.
It is particularly helpful in diagnosing, staging, and monitoring treatment for cancer.
Risks of a PET-CT Scan
A PET-CT scan is generally safe, but there are pet ct scan side effects has some potential risks:
- Pregnancy: Inform your doctor if you're pregnant, as radiation may harm the baby. The scan is usually only recommended in emergencies.
- Breastfeeding: Let the department know if you're breastfeeding. You may need to temporarily stop and store milk after receiving the radioactive tracer.
- Radiation: Exposure to radiation is minimal but can slightly increase cancer risk.
- Bruising/Swelling: Minor bruising or swelling may occur at the injection site. Rarely, the tracer may leak, causing discomfort.
- Allergic Reaction: Very rare, but reactions to the tracer may cause symptoms like weakness or difficulty breathing. Notify the radiographer if this occurs.
Overall, risks are low, and your medical team will ensure your safety.
