Abstract
This study investigated the feasibility of a 3D black-blood STIR TSE sequence with a pseudo steady-state sweep and motion-sensitized driven equilibrium pulse for extraforaminal cranial nerve imaging on a 3T system. Assessments of healthy volunteers showed near-perfect agreement in nerve visualization with excellent to good visualization of the extraforaminal trigeminal, greater occipital, and facial nerves. Suppression of surrounding tissues was excellent to good. 3D cranial nerve imaging can produce nerve selective imaging of extraforaminal cranial and spinal nerve branches.
Highlights
Being the largest cranial nerve, the trigeminal nerve—its inferior alveolar and lingual branches—is frequently damaged during dental, oral, and maxillofacial surgical procedures.[1]
MR imaging has been widely applied to the visualization of cranial nerves.[2]
We developed a novel black-blood 3D STIR TSE sequence for extraforaminal cranial nerve imaging (3D CRANI) on a 3T system and here describe its assessment
