Hi @louiset65, The SUV on a PET scan report refers to the standardized uptake value (SUV). This value is a standardized way to compare across scans how much metabolic activity there appears to be in an area of the body. Cancer, infection, inflammation are all metabolically active. So, the value can help to determine just how active the area may be. They can use this information to determine next steps in the investigation. The PET scan is just one piece of the puzzle that your husband's doctor will use to assess what's happening in your husband's lung.
Are they still looking at doing a biopsy, or did he have one already?
