Temporal Bone Imaging Techniques
摘要
Cross-sectional imaging is the current investigation of choice for a noninvasive detailed assessment of both anatomy and pathology in the temporal bone. Computed tomography (CT) and magnetic resonance imaging (MRI) are both complimentary in this aspect, each having its own merits and demerits. CT provides better spatial resolution and is the modality of choice to assess bony anatomy, fractures, calcifications, cortical erosions, air and fat. MRI offers better characterization of soft tissue lesions, cranial nerve involvement, membranous labyrinth and bone marrow signal changes.
