SUV value, known as standard uptake value (SUV), is a semi-quantitative index commonly used by PET in the diagnosis of tumors, which refers to the activity of the local tissue uptake of the contrast medium versus the systemic average injected activity.SUV=radioactivity concentration of the lesion (kBq/ml)/injected dose (MBq)/body weight (kg). Currently SUV has been widely used in the identification of benign and malignant tumors and evaluation of efficacy, and prognosis prediction.
In addition to factors such as blood glucose level, physical condition of the subject, size of the lesion, outlining of the region of interest (ROI), post-injection imaging time, and clearance of 18F-FDG in the blood circulation, SUV is also affected by factors such as equipment performance, imaging conditions, acquisition modes, reconstruction algorithms, operating methods (e.g., size of the ROI for outlining), and attenuation corrections, all of which can have a certain effect on SUV.
Extended information:
PET check is suitable for the crowd:
1, the social elite Life stress, physical overdraft
The top civil servants, business executives, entertainment stars and other elite class as the pillar of society and family, the responsibility of the work of the pressure, living without regularity, coupled with the more entertainment, the body is in a long-term state of overdraft.

2, long-term history of disease
Because of the disease has been a long time, such as suffering from hepatitis B, chronic atrophic gastritis, etc., most of the weekdays to medication to control, this kind of people need to pay attention to the body check, especially when the symptoms of the degree of gradual aggravation, we must pay attention to.
3, tumor family history of the population
Tumor family history of the population, refers to several generations of the family have a history of cancer. After scientific research, cancer has a certain heredity, especially esophageal cancer, lung cancer, breast cancer, stomach cancer, intestinal cancer and other common malignant tumors, such as parents have such a history, the probability of children suffering from the disease is high.
