Material that strongly scatters radiation rather than attenuating it, violates the assumptions made for the reconstruction.
Metal exhibits strong scattering, so for example teeth with metallic insets produce strong reconstruction artifacts:
As another artifact, patient movement during 180 degree exposure is also a main source of image degradation:
