Positron Emission Tomography (PET) is the most advanced form of controlled use of radioactive substances in the health field. F-18 deoxyglucose (FDG) is a radioactive substance labeled with glucose that is rapidly consumed by cancer cells. With this method, the locations and spread of cancer cells within the body can be easily determined in the most advanced manner. Determining the location and distribution of the disease is the most important information required for the treatment plan. Therefore, PET scintigraphy has become a frequently used method of examination for cancer patients. PET scintigraphy images can be combined with computed tomography images to obtain more precise information about the location of the disease.
However, in some cancers such as prostate cancer, FDG PET is useless and rarely used.
PET / CT scintigraphy may be used instead of FDG. One of them is PS-marked Ga-68. PSMA is a kind of antigen protein found on prostate cancer. The antibody protein corresponding to this antigen protein was produced. The antibody protein finds and sticks to the PSMA antigen protein in the body, such as the same key-lock. In this way, PSMA PET / CT can be used with high precision in the diagnosis and staging of prostate cancer. With this method, patients are not given very high radiation. The processing time will take 30-45 minutes.
Prostate cancer is the most common type of cancer in men. Various methods can be used to treat the disease. However, in order to be decided, it is necessary to know how widespread the disease is. This is called staging. A variety of methods such as CT, MRI, bone scintigraphy can be used to diagnose the disease stage. However, none of them are successful enough. The Ga 68 PSMA PET CT method can be used to monitor the whole body and the spread of diseased tissues is determined with high sensitivity. This method can still be used in very few places in the world. With Ga 68 PSMA PET CT, prostate cancer can be diagnosed in a much shorter time and with fewer procedures, with high sensitivity, and its diffusion is shown.
