In the publicity of some physical examination institutions, PET-CT has obvious advantages and is widely used: “PET-CT can reflect the pathophysiological changes and morphological structure of lesions, and can detect no clinical symptoms. It is a new weapon for scientific cancer prevention.”
PET-CT examination is expensive, is it really necessary to use it in physical examination cancer screening?
At present, in some medical institutions, an appointment for a PET-CT examination costs 7,000 yuan -14,000 yuan. Is it really necessary to use such an expensive examination in routine physical examination for cancer screening? A doctor said: “Some PET-CT medical examination centers even have people waiting in line all year round. The so-called PET-CT is high-end medical imaging diagnostic equipment, which combines positron emission tomography and X-ray tomography. There are two diagnostic methods for scanning. During the examination, the subject is required to inject a contrast agent containing radioactive elements. The most commonly used contrast agent is 18F-FDG. This is a glucose analog containing radioactive fluorine element 18F. PET-CT By detecting the radioactive distribution of 18F-FDG in the body, we can search for malignant tumors with particularly strong glucose metabolism.”ims>width=”60X1ayw/640″ims > (picture from the Internet)
