Artifacts in AC-map and AC-PET caused by foreign bodies. Foreign bodies such as sternal wires and artificial heart valves may cause artifacts in the AC-map, which translates into AC-PET (a overlay of original AC-map and resulting AC-PET). Corrections of the AC-map (b correction of susceptibility artifact by artificial aortic valve, c correction of both artifacts caused by artificial aortic valve and sternal wires) may have a significant effect of about 20% on subsequently calculated AC-PET (relative differences of the corrected AC-PET vs. non-corrected AC-PET, d artificial aortic valve, e artificial aortic valve and sternal wires). AC attenuation correction, ATN attenuation. (Reprinted with permission from Lassen, M.L., Rasul, S., Beitzke, D. et al. J. Nucl. Cardiol. (2017). https://doi.org/10.1007/s12350-017-1118-2)
