Figure 10: The occurrence of artifacts depends on the primary acquisition plane of the CT.
a) 32-year-old female patient; CT of the paranasal sinuses acquired in primary coronal plane. Reduced image quality and diagnostic accuracy due to severe artifacts.
b) 37-year-old patient with chronic rhinosinusits. CT acquired in primary axial plane is degraded by severe artifacts due to dental implants.
c) Secondary reconstructed coronal plane of the same patient as in b. The artifacts are limited to the acquisition plane. Therefore, image quality and diagnostic accuracy of the paranasal sinuses are not reduced.
