EVALUATION OF THE INTERNAL AUDITORY MEATUS WITH ACOUSTIC NEUROMAS USING COMPUTED-TOMOGRAPHY

Forty-seven patients with 48 unoperated acoustic neuromas have been studied by computed tomography (CT) with respect to bone changes. CT and conventional X-ray examination of the skull were compared. The importance of using a small collimator, proper selection of the plane of the CT section and changing of the window level is stressed. CT detects porus changes as accurately as conventional X-ray methods. © 1979 Springer-Verlag.
