PET/SPECT

• Functional information • Help in defining targets(?) • Must be used in conjunction with another imaging modality

• Flood-field uniformity, • Spatial resolution and linearity • Uncertainty: 

Reconstruction method, attenuation correction, calibrations, noise, scatter, random and dead-time corrections  i l d d i i h i i i i d pat ent re ate : ose, mot on, we g t, pat ent act v ty pr or an during uptake, blood glucose level  Radiotracer: uptake period, injection vs calibration, residual activity in syringe, injection method  Image analysis: partial volume correction, analysis software, ROI d fi iti SUV d fi iti e n on, e n on
