Axial PET images after attenuation correction without and with artifact. (A) Axial image of the used MR atlas image for attenuation correction. (B) The same image with the inserted artifact over the second left molar. (C) Base line axial PET image after attenuation correction using the original MR atlas. (D) Corresponding axial PET image after attenuation correction with signal void.
