case_images: Non-contrast CT of neck in axial (a and c) and coronal (b and d) reformats showed the capsule endoscope at the left lower neck. The metal aliasing artefacts obscure the adjacent soft tissues (a and b). The endoscope in Zenker's diverticulum was better depicted after the artefacts were markedly reduced with metal artefact reduction.
