The base of the skull: a comparison of computed and conventional tomography.
The diagnostic information obtained from 35 examinations of the skull base by computed tomography (CT) was compared with the findings furnished by conventional or blurring tomography (BT). Computed tomography yielded diagnostically valuable information not only on the soft tissues but also on the bony structures. Compared with BT, CT was superior in 40%, equivalent in 40%, and inferior in 20% of the cases in assessing pathological findings involving the bony structures of the skull base. Obviously, CT's additional capability of accurate display of soft tissue changes represents a fundamental diagnostic advantage.
