The things you need to be aware of before PET is checked, it makes it easier!

PET is a very advanced image detection method in modern medicine and is often used for tumour diagnosis, heart disease assessment and neurosystem disease detection. If you or your family are going to have a PET check, knowing that some of the attention can make it more efficient and accurate! 1. Attention to the pre-test diet is more than six hours empty: a diarrhea is required before the PET is examined, because the injected visual agent (usually FDG) is a glucose-like substance. If the blood sugar level is too high, it affects the quality of the image. Avoiding high sugar diets: Try to avoid high sugar, high carbohydrates, such as desserts, bread and sugary beverages, on the day before the examination. Drink more water: White water can be consumed at appropriate quantities, but coffee, tea or other sugared drinks are avoided. 2. Are doctors informed in advance of the occurrence of diabetes? If you have diabetes mellitus, especially in cases of poor blood sugar control, please inform the doctor in advance. The doctor may adjust the examination programme to your circumstances to ensure that the results are accurate. A small amount of radiopharmaceuticals is used for pregnancy or lactation PET examinations, and pregnant and lactating women need to be careful and communicate with doctors in advance to assess risks. 3. Inspection of the day ‘ s care to wear comfortable and relaxed clothing: to avoid wearing clothing with metal fittings (e.g. zipping, buttons), which may interfere with scanning. Remove metal items: All jewellery, glasses, watches etc. must be removed before inspection. Quiet and relaxed: After injection of a visual agent, a 30-60-minute rest time is usually required to allow the drugs to be fully distributed and absorbed by metabolic active organizations. To avoid as much activity and tension as possible. Some drugs may need to be discontinued (e.g., those affecting blood sugar levels or anti-inflammatory drugs) and may interfere with PET visual effects. Before the examination, it is recalled that the list of drugs being taken is given to the doctor for appropriate adjustment. 5. Post-inspection PET inspections of radioactive substances used are natural metabolisms in the body, which are generally not harmful to the body, but in order to release residual radioactive material in the body more quickly, the examination recommends that: drink more water: promote urine and accelerate metabolic. Avoiding long-term contact with pregnant women and children: Although the radiation dose is low, every effort is made to avoid direct contact with pregnant women or children at a close distance of more than two hours after the examination. While the PET examination is efficient, the accuracy of the results depends on the patient ‘ s cooperation. Doing this is not only helping the doctors to diagnose better, but also making your examination experience better!
