These glitches commonly decrease with improved lesion size and/or decreased respiratory motion14. Respiratory results can introduce additional problems in the form of picture artifacts crop up from positional mismatch of the PET knowledge plus the CT visuals employed for attenuation correction38. As for many of the things that affect SUV accuracy, improvements in client respiratory patterns involving serial scans as a consequence of changes in the acquisition protocol (for example, patient anxiousness, respiration sample coaching because of the technologist, or space ambiance) will confound the ability to measure real adjustments in SUV.
