    Abstract: A novel technique of quantifying nuclear medicine data is provided. The novel technique is characterized in that information acquired from nuclear medicine image data is normalized with bone mineral content (BMC) or bone mineral density (BMD). Some embodiments use, instead of the conventional SUV, the SUVbone that has been invented by the inventors of the present application such as the following: SUVbone={Amount of attenuation-corrected radioactivity in region of interest (kBq)÷Volume of region of interest (ml)}/{Administered radioactivity dose (kBq)÷Bone mineral content (g)} or SUVbone={Amount of attenuation-corrected radioactivity in region of interest (kBq)÷Volume of region of interest (ml)}/{Administered radioactivity dose (kBq)÷Bone mineral density (g/m2)}. BMC or BMD may be estimated from sex, age, height, or weight of a subject.
