Abstract:
:CT and MR imaging increasingly are being used for the evaluation of the skull base. New innovative techniques have revolutionized radiologic understanding of normal skull base anatomy. Thus, normal anatomic relationships with radiographic correlation are vital for accurate pathologic assessment.
