Universal detectors cancer does not exist
Modern research method, a total body positron emission tomography (PET) is becoming increasingly popular in science and medicine. Allowing for the diagnosis and therapy of certain types of cancer, this technology, however, is not universal, and is often wrong.
Question about the scope of the PET, were delivered by researchers from the Public health service in the U.K. (U.K. National Health Service). It is known that PET-scan is one of the most modern methods of diagnosis and determining the level of activity cancer. This technology is more accurate and efficient than other currently existing methods. With the help of radioactive elements, positron emission tomography can, with high accuracy, to identify carcinogenic cells from normal tissues, experts say.
The most typical form of pet scan, FDG-PET appeared as a result of the difficulties in the diagnosis and treatment of large-cell carcinoma and lung cancer. This form of imaging is suitable for patients with Hodgkin’s lymphoma, and allows to determine the optimal method of therapy for people suffering from cancer of the colon and rectum.
“In the case of other types of cancer, positron emission tomography allows to establish the diagnosis, i.e. to identify the tumor, however, can give erroneous results in selecting the optimal method of treatment and assessing the patient’s chances of survival,” notes Dr. Karen Pasi (Karen Facey), a member of the research project.
Thus, the researchers concluded that this type of diagnosis is not universal, and is best suited for diagnosis and choice of treatment for large-cell carcinoma and lung cancer, and in Hodgkin’s lymphoma, experts say.
