Recently, wang engaged in financial work in Beijing saw a let him move weibo: "it is strongly recommended that aged parents do at least once a year to the family's PET - CT, best done once every six months. PET - CT can detect early cancer, but often less than a year, becomes late." After consulting a doctor, however, Mr Wang dismissed the idea. 
 
        Like Mr Wang, a lot of people are concerned about the health of himself and his family. At present, in the high-end check-up packages, PET - CT become the hottest recommended options.

        "High-end medical examination, can be as simple as PET - CT examination." "A PET - CT as a high-end medical examination, has become a cancer checkup of western country will do every year, the current domestic is highly successful people preferred." This is a PET - CT inspection booking website to high-end medical explanations. 
 
        Investigative reporter learned that, the so-called PET - CT, is a high-end medical imaging diagnostic equipment, it is a combination of positron emission tomography and X-ray tomography two diagnostic ways. In the process of inspection, the need of client developer containing radioactive elements, by far the most common developer is "18 f - FDG". It is the element fluorine containing radioactive glucose analogue of 18 f. 18 f - FDG PET - CT by detecting radioactive distribution in the body, the glucose metabolism was particularly strong for malignant tumor. 
 
        In the propaganda of medical organizations, the advantages of PET - CT clearly, USES a wide range of "PET - CT can reflect the pathological physiological changes and morphology of lesions, and can detect small lesions without any clinical symptoms, more than six months earlier than conventional CT and mri to find lesions, is the new weapon of science cancer." However, the relevant medical experts are opposed. 
 
        Abuse of PET - CT is a commercial hype, causing the waste of medical resources. Of doctor of vice director of tsinghua university, chang gung memorial hospital surgery, surgical oncology expert Dr LinHongWei said: "a PET - CT number for late diagnosis and localization of tumor recurrence, or source of tumor diagnosis. Regular physical examination isn't necessary to do PET - CT examination. Many online use of PET - CT screening examination early cancer cannot be ruled out commercial hype. Lead to many people follow a medical, comparing, blindly is not reason to do so." 
 
        "Not everyone needs to do PET - CT examination, even some cancers check is not sensitive to this, this check is the main purpose of assessment of combination therapy for cancer treatment, judging curative effect before and after chemotherapy, for example, if there is a recurrence, transfer, etc. Use expensive PET - CT screening to normal tumor, is not only a waste of resources, and also have damage to the human body." LinHongWei added. 
 
        In fact, PET - CT does not screen out all of the tumor. Fuzhou general hospital of nanjing military region, director of oncology OuYangXueNong argues that the main effect of PET - CT should be on the track of tumor treatment, provide dynamic monitoring of clinical treatment. Remove price, risk factors, such as PET - CT found in cavity viscera, such as the esophagus, stomach, intestines, etc.) pathological changes there is a blind area, plus food scraps and intestinal peristalsis, PET - CT can't take the place of gastroscope and enteroscope. Can't replace the CT and MRI. Do check should follow the principle of simple to complex, namely do B ultrasonic, CT, MRI, and then do a PET - CT. 
 
        Preventing cancer, PET - CT is useless. LinHongWei believes that "the key to reject smoking and secondhand smoke, don't eat cooking oil, away from the car exhaust, resist unhealthy food. Looking for a professional doctor, targeted physical examination for high-risk groups, such as the stomach, chest CT thin layer as a routine examination items of high-risk groups, and routine abdominal, breast, gynecological, thyroid ultrasound, cervical smear, serum tumor markers, etc." 
 
        Booking website suggest PET - CT as high-end medical examination content, "to do" a year, experts say it is not necessary. In fact, the original ministry of health has issued notice requirements "strict access, standard application". 
 
        The 2011-2015 national type positron emission tomography configuration planning "asked:" medical establishment standard strictly, in order to strengthen the management of access, assessment of strengthening the training of professional and technical personnel, improve the level of business, specification to use, protecting the legal rights and interests of patients. PET - CT examination rate of not less than 70%." 
 
        So, despite the economic factors, use PET - CT as a routine examination project, itself is there side effect? With and without harm to the body? This exhibition will be open to further investigation to this issue.
