Multiplanar MR and anatomic study of the mandibular canal
Abstract
Purpose: To evaluate the MR appearance of the mandibular canal and its contents.
Methods: Cadaveric mandibles were imaged at 1.5 T and 3 T, then sectioned with a cryomicrotome. The size, shape, signal intensity, and pattern of structures in the mandibular canal were identified on MR images by comparing them with corresponding anatomic sections.
Results: The inferior alveolar nerve and connective tissue were identified on the 1.5-T and 3-T images in the mandibular canal. Within the nerve the axon bundles were distinguished from the nerve sheath on the 3-T images.
Conclusion: This study suggests that MR images can show excellent anatomic detail in the mandibular canal.
