Lei Xiao: What preparations do patients and their families need before PET/CT examination?

In my country, PET/CT examinations are widely used in the diagnosis of tumors, neurological diseases, cardiovascular diseases and other fields. In order to ensure the accuracy and safety of the examination, in addition to the rigorous preparation of medical staff, patients and their families also need to make corresponding preparations. The following is a detailed explanation of the preparations that patients and their families need to make before the PET/CT examination.

First of all, it is very important for patients to adjust their diet before the examination. Patients need to fast before the examination because glucose and drugs will compete with each other after eating, which will affect the intake and metabolism of drugs. At the same time, drugs containing ingredients such as glucose and energy milk should be avoided to avoid affecting the effect of the drugs. Fortunately, fasting does not mean abstaining from water. Patients can drink plain water normally to ensure the body's water needs.

Secondly, patients should try to avoid strenuous exercise before the examination. This is because strenuous exercise may cause changes in metabolites in the body, thus affecting the accuracy of the diagnosis results. For this reason, patients should keep their bodies calm before the examination and avoid physiological fluctuations caused by exercise.

Finally, patients need to avoid fatigue before PET/CT examination to ensure that their bodies are in the best condition during the examination. In addition, they should avoid some examinations that produce metal components in the body, such as magnetic resonance imaging, before the examination, because these examinations may affect the effect of PET/CT examination.

Here, we want to emphasize the importance of preparation before PET/CT examination. Patients and their families need to strictly follow the requirements of medical staff to ensure the smooth progress of the entire examination process. Only in this way can PET/CT examination play the greatest diagnostic value.

In short, the preparations before PET/CT examination involve many aspects. Patients and their families need to actively cooperate with the guidance of medical staff and make all preparations. Through everyone's joint efforts, we can ensure the accuracy and safety of the examination and provide strong support for the diagnosis and treatment of patients. At the same time, it also allows patients and their families to have more confidence in the face of the disease, actively cooperate with treatment, and create a better future together.
