Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Up to now, multiplanar reconstruction (MPR) has been widely used to detect the neurovascular compressions (NVC) on the patients with idiopathic trigeminal neuralgia (ITN). However, due to lack of stereoscopic vision, this traditional method sometimes cannot meet the requirement on identifying the existence and details of NVC, especially when the aberrant vessels turn out to be delicate veins. The three-dimensional analytic techniques, such as curved planar reconstruction (CPR) and magnetic resonance virtual endoscopy (MRVE), may be helpful to improve the sensitivity and specificity on the demonstration of NVC with stereo and dynamic views, so as to assist to design the surgical plan.

Furthermore, the frequent finding of NVC on MRI studies of asymptomatic patients incited the creation of several strict criteria for the imaging diagnosis of NVC: the vessel must cross perpendicular to the long axis of the nerve, the nerve must be deviated or indented at the root entry zoon (REZ) by the vessel. Alternatively, morphological measurement of the nerve may correlate with the severity of facial pain due to atrophy of the nerve in most cases of ITN, and is likely secondary to the micro-structural abnormalities, such as axonal loss, demyelination, collagen deposition, etc. In this study, cross-sectional area (CSA) and volume (V) of the cisternal trigeminal nerve will be assessed to determine whether it can be a useful biomarker for predicting the degree of ITN.
