What is the significance of PET-CT examination for tumor disease?

PET is called positron emission computed tomography (PET), which is a imaging device that reflects the genetic, molecular, metabolic and functional status of lesions.It uses positron nuclide labeled glucose and other human metabolites as imaging agents, and reflects its metabolic changes through the uptake of imaging agents in lesions, so as to provide biological metabolic information for clinical diseases.Do PET-CT examination what effect and significance are there?1, the differentiation of benign and malignant tumors or lesions is very important, not only related to the treatment plan, but also directly affect the prognosis of patients.If the patient has a single pulmonary nodule, peT-CT examination shows that the metabolic activity of the nodule is not high, indicating a high possibility of benign lesions, the choice of surgery should be cautious.Conversely, if the nodule’s metabolic activity is elevated, suggesting malignancy, aggressive treatment, including surgery, may be required.2. Efficacy evaluation Due to the high sensitivity and functional metabolic imaging characteristics of PET-CT, the judgment of radiotherapy and chemotherapy efficacy is more accurate and sensitive, which is conducive to guiding clinicians to adjust treatment plan in time.Pet-ct can distinguish tumor necrosis, fibrosis and residual or recurrence after chemotherapy, radiotherapy and surgery, while other imaging methods are difficult to do.Pet-ct can help the radiation therapist to delineate a more reasonable biological target and help to plan radiation therapy.5. Search for primary tumor foci For patients with confirmed tumor metastasis, peT-CT examination can further search for primary tumor foci.Statement: This article copyright belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through email, we will promptly deal with.Email address: jpbl@jp.jiupainews.com
