About the Department


how is a ct scan done ? The first diagnosis, staging, determination of the prevalence of the cancer and the correct treatment plan for the removal of all phases of the PET/CT device is performed. With the PET/CT, the cancer map is removed and an effective struggle is provided with this disease.

Positron emission tomography (PET) technology is combined with computerized tomography (CT), a very important medical imaging method that allows the diagnosis of many diseases.


PET/CT; It is largely used in cancer patients. But other than that, it is used in the presence of an unknown fever in the absence of infection, in the determination of live tissue in cardiac patients, in the separation of Alzheimer's and dementia.

How is the PET-CT process done?


For PET/CT operation, the patient must have a minimum of 6 hours of fasting. First, the patient's blood glucose is measured. Blood sugar is injected with radioactive material from the vein at the desired limits. While there are a variety of radioactive substances, the most used is the F-18 florodeoxyglytosis. This substance is a sugar molecule linked to the radioactive substance of the Flor-18. Following the injection, the patient is suspended for the dissolution of the drug for an hour. The PET/CT device is then taken to shoot.


Other substances used in PET-CT, F-18 NAF to display the bones, GA-68 Psma in the research of the spread of prostate cancers, GA-68 Octerotiditir used for the research of neuroendocrine tumors. Furthermore, there are many radiopharmactics that are not used in the routine.


From the detection of PET-CT cancer tissue, the treatment plan increases dramatically in the battle with cancer in many stages, from evaluating treatment success to planning the treatment of radiation.

PET/CT is utilized in every phase of cancer diagnosis and treatment


The most important difference of cancer cells from normal cells is rapid and uncontrolled proliferation. The energy needs of high-functioning cells are also more than normal. When substances such as sugar, protein and certain special building blocks that are used in this process of cancerous cells are marked as radioactive, the location of cancerous tissues can be detected. The PET/CT device works on the basis of this logic.

Pet/CT, which gives direction to cancer treatment, is used in the following stages of diagnosis and treatment;


It is utilized to determine the metabolism of tissue that is suspected of cancer

It is diagnosed with PET-CT, where the masses identified by various imaging methods showed cancer metabolism. If the PET-CT is positive in the mass, this mass consumes a large amount of glucose and is likely to have cancer.

Removal of parts from the right place from the tissue that has a cancer bird


Cancerous tissue can also create damage in its structure due to uncontrolled proliferation. Not enough cells can be obtained for identification from the tissue fragments to be taken from the damaged area, the PET/CT shows the areas where the live cells are concentrated and becomes a guide to the biopsy.


Evaluation of cancer prevalence


PET/CT technology is used in the first stage after the diagnosis of cancer, with the success of many cancer types in order to evaluate the prevalence of disease (evrelization).


Determination of treatment approach


After this examination, an average treatment approach varies in one of three patients. Sometimes medication can be performed instead of a heavy surgical procedure and unnecessary surgery can be avoided. In some cases, PET/CT may lead to the decision to remove the cancerous tissue from the surgery rather than the drug treatment decision, showing that there is no spread in the patient who is thought to have distant emissions.

Early detection of the benefit of cancer medicine

The side effects of cancer medications are medications that need to be cared for. The use of the appropriate drug will save both unnecessary side effects and the chance of preventing disease with the right medication and early intervention in cancerous tissue. 1 or 2 of the treatment. The evaluation of the PET/CT after the curing is about how beneficial the drug can be.


Determination of treatment response


The response to Cancer medicine with PET/CT is evaluated by numerical measurement of both structural changes and the severity of cellular activity. After the treatment is completed, the treatment activity can be determined by researching the presence of the live cancer cell. PET-CT is the earliest imaging system that responds to treatment.


Preparation of the radiation treatment plan


Live tumor cell areas that will be given radiation in radiotherapy or light treatment can give a more accurate and effective treatment with PET/CT mapping, and prevent any unnecessary side effects by preventing the beam to be given to healthy tissues Decrease.


Early detection of recurrent disease

After completion of treatment cures, patients are followed by methods and blood tests such as ultrasound and tomography. If there is a suspicious situation in these methods, live cancer cells are re-emerged and its prevalence is determined by the PET/CT method successfully.


Our PET/CT device is located at Memorial Sisli Hospital, Memorial Diyarbakır Hospital and Memorial Health Group MedStar Antalya Hospital.
