In this article, we will discuss about the need and purpose of PET-CT and also some common questions related to PET-CT.
Overview
PET-CT is the short form of PET-CT scan is the short form of positron emission tomography (PET) and computed tomography (CT). It is the non-invasive radiological diagnostic tool which is used to create clear 3D images of the abnormal area for diagnostic purpose. The procedure also used radioactive tracer for the detection of abnormality. PET-CT is used to detect various cancer conditions in the body at the aearliest stages and helps in early and effective treatment of the condition.
What is PET-CT Scan?
PET-CT scan is the short form of positron emission tomography (PET) and computed tomography (CT) is the diagnostic procedures used for the detection of abnormalities in the body. PET-CT uses administration of radioactive tracers for to produce clear images of the tissues organs for the early detection of abnormalities, while CT uses computerized X-rays to produce images of the diagnostic area. PET-CT scan is the combination of both these procedures to create 3D images which allows for accurate and exact diagnosis. This helps in easy and early detection of abnormality and helps in targeted effective treatment.
What is the Procedure of PET-CT Scan?
In the procedure of PET-CT scan, patient is administrated with the radioactive tracer like FDG or F-18. After administration, patient is advised to wait for at least 1 hours so that radioactive tracer reaches to whole body. Then patient is advised to lie on the table attached with the PET-CT machine, the table slides into the machine for the procedure. The machine uses motorized X-rays in the limited quantity to detect the activity of the tracer. Then clear 3D images are produced by the scanner for the diagnosis purpose.
What are the uses of PET-CT?
PET-CT (positron emission tomography -computed tomography) is a radiological imaging procedure used to detect abnormalities that can’t be detected in X rays or CT scans. The procedure uses the radioactive tracer for diagnostic purpose and has various uses like:
- Cancer diagnosis
- Stage of Cancer
- Extent of spread of cancer
- Effect of treatment on cancer
- Helps to plan the treatment of cancer
- Helps to detect heart diseases
- Helps in recognizing brain disorders
- Monitoring other abnormal conditions of the body
What is radioactive tracer used in PET-CT scan?
Radioactive tracer is the chemical compound used in the PET-CT diagnosis purpose by assessing the movement of tracer in the body. This chemical compound is tagged with small amount of radioactive material designed to mimic the natural substances and attach with the cells. The most common radioactive tracer used is FDG (fluorodeoxy glucose). This is the modified glucose that is attached with small amount of radioactive element. As the radioactive element decays, it emits positron which is detected by PET scanner. This helps in the detection of abnormality in the body.
What does PET-CT Scan Shows?
PET-CT scans produce the 3D images of the tissues, organs, muscles etc. This helps in easy detection of abnormalities in the body. Healthcare experts look for various conditions inside the body through PET-CT scan like:
- Cellular changes in the body
- Metabolic activity at the minor scale
- Reveals the functioning of organs
- Provides anatomical images of bones, tissues and organs
- Detects abnormalities in the body etc.
Conclusion
PET-CT scan is the short form of positron emission tomography (PET) and computed tomography (CT) is the diagnostic procedures used for the detection of abnormalities in the body. PET-CT uses administration of radioactive tracers for to produce clear images of the tissues organs for the early detection of abnormalities. The patient is administrated with the radioactive tracer like FDG or F-18 and advised to wait for at least 1 hours so that radioactive tracer reaches to whole body. Then patient is advised to lie on the table attached with the PET-CT machine to detect abnormality in the body. There are various uses of PET-CT scan like cancer diagnosis, stage of Cancer, extent of spread of cancer, effect of treatment on cancer, helps to plan the treatment etc.
