What is normal suv on pet scan?

A normal SUV (Standardized Uptake Value) on PET scan refers to the level of radioactivity detected in a certain area of the body after the injection of a radiopharmaceutical tracer. The SUV is a measurement of how much radiotracer has been taken up by the tissues being scanned.

A normal SUV value varies depending on the type of radiopharmaceutical used, the patient's body weight, and the area of the body being scanned. However, in general, an SUV value of less than 2.5 is considered normal.

In cancer imaging, SUV values are used to assess the metabolic activity of tumors. Higher SUV values can indicate greater metabolic activity and thus, potentially more aggressive or advanced tumors. However, it is important to note that a high SUV does not necessarily mean that the tumor is cancerous, as there are many other factors that can affect SUV values.

Overall, SUV values are just one piece of information used by doctors to interpret PET scan results and make treatment decisions.
