Gallium 68 PSMA PET BT

Ga 68 PET/CT IMAGING with PSMA

Positron Emission Tomography (PET) is the most advanced form of the controlled use of radioactive materials in the field of health. F-18 deoxyglucose (FDG) is a radioactive substance of glucose that is rapidly consumed by cancer cells. With this method, the location and spread of cancer cells in the body can be easily determined in the most advanced way. Determining the location and distribution of the disease is the most important information necessary for the treatment plan. For this reason, PET scintigraphy has become an examination method frequently applied by cancer patients. By combining PET scintigraphy images with computed tomography images, more precise information about the location of the disease can be obtained.
However, in some types of cancer, such as prostate cancer, FDG PET is useless and is rarely used.

Other drugs can be used instead of FDG in PET/CT scintigraphy. One of them is PSMA marked with Ga-68. PSMA is a type of antigen protein found on prostate cancer. The antibody protein corresponding to this antigen protein was produced. The antibody protein finds and adheres to the PSMA antigen protein in the body, just like a key-lock. In this way, PSMA PET/CT can be used with high sensitivity in the diagnosis and staging of prostate cancer. With this method, patients are not given very high radiation. Processing time takes about 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 decide on this, it is necessary to know how widespread the disease is. This is called staging. Various methods such as CT, MRI, bone scintigraphy can be used to know the stage of the disease. However, none of these are successful enough. With the newly introduced Ga 68 PSMA PET CT method, the whole body can be imaged and the spread of diseased tissues is detected with high sensitivity. This method is still used in very few places in the world. With Ga 68 PSMA PET CT, prostate cancer can be diagnosed and spread with high sensitivity in a much shorter time and with fewer procedures.
