High resolution CT scan of the temporal bone.
With the new high resolution CT scanners with target reconstruction, detailed radiological anatomy can be assessed. Hence, very small structures within the petrous portion of the temporal bone are accessible owing to better density resolution. Not only bony structures but also soft tissue elements are directly visible, which represents an advantage over multidirectional conventional tomography. This technique is described and examples of the normal anatomy of the temporal bone are presented.
