Yes: Pet scans pick up cancer or inflammation. Many acute infections will light up pet, but the suv characteristics and the appearance of the nodule help the radiologists. Still.. Pet is not a perfect test and there may be uncertainty. Sometimes a biopsy is required to make a diagnosis.

Yes: Pet scan identifies increased cellular metabolism. The suv is a measure of how metabolically active the nodule is. It does not diagnose the cause of the increased metabolism. Inflammation from any cause, including infection stimulates increased metabolism. It is important any lung nodule be thoroughly investigated and closely followed by a comprehensive thoracic team.

Yes: Infectious, inflammatory, and malignant conditions can all light up on PET scan. There is overlap between SUV's in these conditions so there is no exact number where one can have a threshold between benign and malignant. If PET is negative, this usually means the nodule can be watched closely and no immediate biopsy is usually needed. CT characteristics of the nodule can also be helpful.
