Small chemodectomas in the middle ear cavity can be recognised by otoscopy, but only radiology will show if the jugular bulb is involved. This assessment can be difficult, but largely governs the surgical approach. Magnetic resonance is a valuable adjunct to CT, providing some tissue characterisation. The relative value of various imaging techniques is discussed.
中耳腔内的小化学感受器瘤可通过耳镜检查识别，但只有放射学检查才能显示颈静脉球是否受累。这种评估可能很困难，但很大程度上决定了手术方式。磁共振成像（MRI）是CT的重要辅助手段，可提供一些组织特征。本文讨论了各种成像技术的相对价值。
