Don't know: Importance of pet scan is to show activity or glucose metabolism of lesions. This is usually expressed as numbers reflecting units of suv. Ct or radiographs demonstrate sclerosis or increased density of bone lesions.

PET: Do you have any history of cancer? Did the lesions have any FDG uptake on pet? Lesions that size may be below the resolution of pet imaging. It is hard to know without having your history and seeing the images. Fdg is a nonspecific tracer and can be taken up in tumor, infection, and inflammation.
