In this article, we will discuss about the disadvantages of PET-CT as a diagnostic tool for the detection of cancers and also some common questions related to PET-CT.
PET-CT is the short form of Positron Emission Tomography-computed tomography, which is a technique used to look for different cancers in the body. The procedure has various advantages like early detection and gives comprehensive view of both metabolic and anatomical structure. But the procedure is having also various disadvantages like using of radioactive tracer, exposure to radiation, allergic reactions. Disadvantages will be discussed in detail in this article.
What is PET CT Scan?
PET-CT (Positron Emission Tomography-Computed Tomography) is the advanced radiological technique which is used to detect the cancers. The procedure uses both radioactive tracers and X-rays for the detection of abnormalities by creating 3D images of the area.
What are the Disadvantages of PET-CT Scan?
PET-CT is advanced non-invasive radiological procedure used for the detection of cancers in the body. This technique is popular with many advantages but the procedure has also some disadvantages like:
Radiation Exposure:
The procedure involves radiation usage for creating 3D images and too much exposure of radiation can be dangerous for the body. Some radiations can trigger the cell irritation and can lead to abnormalities in the cell.
Radioactive Tracer:
PET-CT uses radioactive tracer like FDG for the detection of diseases. This tracer sometimes can cause allergies in some patients. Sometimes allergies can be very serious leading to organ damage.
False Results:
Sometimes the PET-CT scan can create false positive and false negative results. Some cells can take more glucose in the areas of inflammation and can mimic cancer cells. Similarly cancer cells with low metabolic rate cannot be detected.
Cost and Availability of the Scan:
PET-CT scan is costly and cannot be affordable for all the patients especially from very poor background. Also availability of the scan is very rare in the rural areas.
Patient Motion During the Scan:
Patient has to be still during the scan to get clear images for the diagnosis purpose. Any movement can blur the images and can impact the diagnosis. This condition can be challenging to some patients which may be having some medical conditions, anxiety or fear of isolation during the scan.
