Computed tomography of the skull and facial structures: preliminary evaluation of direct coronal sections

Skull and facial structures may be evaluated on computed tomography (CT), as well as the brain. A valuable new dimension to the study has been added with the feasibility of obtaining direct coronal sections using a wide gantry aperture. The patho-anatomical details of bone and soft tissues including the orbit and paranasal sinuses are well demonstrated. Direct viewing on a display console of an enlarged quadrant of the scan is of prime importance in diagnosing fine changes involving the thin facial bones.
