What is PET- CT?
PET/CT; It is an imaging method formed by the combination of PET (Positron Emission Tomography) and CT (Computerized Tomography) devices, which allows to obtain metabolic and anatomical information about organs together. PET CT method, which is used primarily in the monitoring of cancer diagnosis and treatment, is also used in the diagnosis and treatment of cancer as well as oncological diseases, heart attack, epilepsy and Alzheimer's.
What are the Advantages of PET-CT?
Not only can it show which tissues and organs the diseases affect in the body, it can also detect the vitality of the cells that cause the disease by scanning the whole body. By this way, it is possible to evaluate whether the disease is active or not. It allows to understand how much response is received to the treatment.
How PET-CT is Applied?
The most commonly used method is intravenous administration of radioactive Fluorine 18 glucose (sugar) and bound glucose and scanning the whole body. It is based on the principle of keeping sugar in areas that use high sugar such as cancerous tissue, heart muscle, brain tissue and detecting it with PET / CT device.
Where is PET-CT used in?
• Helps distinguish cancer-suspected masses from non-cancerous diseases
• It is a guide in taking parts from the active and live areas of cancer-suspected masses.
• It is useful in detecting cancers of unknown origin.
• It is the most successful method for detecting the spread of cancer after diagnosis.
• It has an important role in determining the right treatment approach to cancer patients and preventing unnecessary interventions or surgeries.
• It contributes to the determination of the effectiveness of cancer drugs.
• It is important in determining the response status after cancer treatment.
• It contributes to the correct planning of radiation therapy.
• It illuminates the suspicion of recurrence in cancer.
• Changes that occur after treatments such as radiation or surgery have an important place in distinguishing the actual disease state.
• It detects the presence of living tissue in the heart muscle.
• It predicts whether there will be benefit from cardiovascular replacement surgery (bypass) and guides the treatment decision.
• It is helpful in determining the focus of epilepsy.
• It guides the surgeon by detecting the diseased area in epileptic patients who can be operated.
• It provides early detection of dementia (Alzheimer's).
• It is useful in differentiating the diseases that cause dementia.
Diseases such as infection (microbial), inflammation, granulomatous (sarcoidosis), autoimmune (IgG-related disease), fever of unknown origin.
