PET CT scan side effects : Understanding the risks and complications.

PET CT (Positron Emission Tomography - Computed Tomography) is a medical imaging technique that combines the use of radioactive tracers with CT scans to produce detailed images of internal body structures. While PET CT scans are generally considered safe, like any medical procedure, they do come with some risks and potential side effects. In this article, we will discuss some of the possible PET CT scan side effects.

1. Allergic reactions: Some patients may experience an allergic reaction to the radioactive tracer used in PET CT scans. Symptoms may include itching, hives, and difficulty breathing. In rare cases, a severe allergic reaction known as anaphylaxis may occur, which can be life-threatening.

2. Radiation exposure: PET CT scans involve the use of radiation, which can increase the risk of cancer and other health problems over time. However, the amount of radiation used in PET CT scans is generally considered safe.

3. Nausea: Nausea is a common side effect of PET-CT scans, particularly when patients receive contrast material. Some patients may experience nausea or vomiting after a PET CT scan. This is usually mild and goes away on its own within a few hours.

4. Headache: Headaches are a common side effect of PET CT scans. They are usually mild and go away on their own within a few hours.

5. Dizziness: Some patients may experience dizziness or lightheadedness after a PET CT scan. This is usually mild and goes away on its own within a few hours.

6. Pain or discomfort: Some patients may experience pain or discomfort at the injection site or in other parts of the body during or after the PET CT scan.

Conclusion :

while PET CT scans are generally considered safe, they do come with some risks and potential side effects. It is important to discuss these risks with your doctor before undergoing a PET CT scan.

At Medipulse Hospital, our experienced medical professionals take all necessary precautions to minimize these risks and ensure that our patients receive the best possible care. If you have any concerns or questions about PET CT scan or any other medical procedure, our team is always available to provide you with the information and support you need.

Understanding PET CT Scan - How it works and what to expect

PET CT (Positron Emission Tomography - Computed Tomography) is a medical imaging technique that combines the functional information of PET and the anatomical details of CT to produce highly detailed images of the human body. During the scan, a small amount of radioactive tracer is injected into the patient's bloodstream, which is then absorbed by the organs and tissues being imaged. As the tracer decays, it emits positrons which collide with electrons and produce gamma rays. These gamma rays are detected by the PET scanner and used to create a three-dimensional image of the body's metabolic activity. The CT scanner then produces a detailed anatomical image of the same area.

Techniques used in PET CT Scan:

The following are the techniques used in PET-CT scan:

1. Radiotracer injection: Before the scan, a small amount of radioactive material known as a radiotracer is injected into the patient. The radiotracer is usually a sugar molecule tagged with a radioactive atom.

2. PET imaging: The radiotracer emits positrons, which collide with electrons in the body, producing gamma rays that are detected by a PET scanner. PET imaging produces three-dimensional images of the distribution of the radiotracer in the body, indicating areas of high metabolic activity.

3. CT imaging: A CT scan is then performed immediately after the PET scan. The CT scan uses X-rays to produce detailed images of the internal structures of the body. This provides anatomic information that helps to identify the location of abnormal metabolic activity detected by the PET scan.

4. Fusion imaging: The PET and CT images are combined using special software to create fused images. The fused images provide a more accurate and comprehensive view of the body, enabling physicians to identify and locate abnormalities.

5. Image interpretation: The fused images are interpreted by a radiologist or a nuclear medicine specialist, who looks for areas of abnormal metabolic activity that may indicate the presence of cancer or other diseases.
