What is the cause of specific constitution

summary

Pet, fully known as positron emission computed tomography (PET), is an imaging device that reflects the gene, molecular, metabolic and functional status of lesions. CT full name for computer X-ray tomography technology, it is the use of X-ray body layer examination of the human body. PET-CT: organically combine pet and CT, use the same examination table to share an image workstation, PET-CT has the functions of pet, CT and PET image and CT image fusion. It is the use of positron nuclide labeled glucose and other human metabolites as imaging agents, through the uptake of imaging agents to reflect the metabolic changes of lesions, so as to provide clinical biological metabolic information of diseases. Specific constitution of the people do CT disease what reason to tell you.

What is the cause of specific constitution

First: tumor high-risk groups: tumor high-risk groups are very suitable for PET-CT examination once a year. The definition of tumor high-risk groups is relative. Different tumors and different regions may have very different high-risk groups. The accuracy of PET-CT is much higher than other imaging equipment.

Second: patients diagnosed with cancer: for patients diagnosed with cancer, PET-CT examination has many functions, such as finding the primary tumor, conducting whole-body imaging to determine whether there are metastatic lesions, staging and grading the tumor, assisting doctors in formulating treatment plans, and providing biological target location for radiotherapy.

Third: sub healthy people: for people in sub-health, more attention should be paid to physical examination. Some people have no symptoms in the early stage, but the symptoms are often advanced cancer. PET-CT physical examination of normal people can find out whether there are dangerous small lesions in the body, so as to make early diagnosis and treatment.

matters needing attention

Do not drink alcohol, do not do strenuous exercise, do not exercise for a long time 24 hours before the examination, it is best to ensure a light diet. Fasting, drinking sugary drinks and intravenous infusion of glucose should be prohibited 6 hours before the examination, and a small amount of water can be used; patients with diabetes should use hypoglycemic drugs normally, so as not to affect the examination time and effect due to high blood glucose.
