FIGURE 2. 18F bone scan MIP images without and with attenuation correction for small and very large patients. (A and B) Emission-only and attenuation-corrected anterior view of small-framed patient. (C and D) Emission-only and attenuation-corrected anterior view of obese patient. Attenuation correction is vital for detection of small lesions and provides excellent imaging of very large patients. PET is more sensitive than single-photon imaging to attenuation effects.
