Abstract

Because of the inherent complex anatomy and functional arrangement of the cranial nerves (CNs), neuroimaging of cranial neuropathy is challenging. With recent advances in magnetic resonance imaging (MRI) techniques, the cause of cranial neuropathy can now be detected in many cases. As an active multidisciplinary team member of cranial neuropathy, it is essential for the neuroradiologist to be familiar with the detailed anatomy of the CNs on MRI. This review contains the basic MRI anatomy of CNs III-XII according to a segmental classification from the brain stem to the extracranial region. The optimal imaging options to best evaluate the specific segment of the CNs will also be discussed briefly.

복잡한 해부학적 구조와 기능 때문에 뇌신경 질환의 신경영상검사는 항상 어려운 과제이다. 최근 자기공명영상(이하 MRI) 기법의 발달로 많은 경우에서 뇌신경 질환의 원인이 규명되고 있으며, 신경영상의학 의사들은 다학제 팀의 핵심적 팀원으로서 다양한 뇌신경 질환의 원활한 진단을 위하여 MRI에서 관찰되는 뇌신경의 세밀한 해부학적 구조를 잘 알아야 한다. 이 종설에서는 말초성 뇌신경 III-XII에 대해 뇌간으로부터 두개 밖까지 해부학적으로 비슷한 구조를 가지는 구역별로 분류하여 각 구역에서 보이는 뇌신경의 정상 해부학 및 MRI 소견을 설명하고자 한다. 또한 각 구역에서 가장 적합한 MRI 기법에 관하여도 기술하고자 한다.
